Using
What We Learn To Develop More Free Online Fiber U Courses
Last
month, we ran an article about "What
We Learn From FOA Certification Tests" that
showed the questions that CFOT candidates missed most on the
certification exam were about testing. The three largest
categories included OTDRs and information in the traces, the
meaning of dB and dBm, loss budgets and insertion loss
testing. Last was the units of measurement we use in fiber
optics.
FOA is working its way down that list to create new free
Fiber U MiniCourses on those very topics. We've already done
dB/dBm
and loss
budgets, just created a new one on Reading
OTDR Traces. Insertion loss and units of
measurements come next.
If you have ideas for more free Fiber U courses, send
us an email and let us know.
Two
More New Free Fiber U MiniCourses
Reading OTDR Traces And Midspan
Access
FOA has
created two more free Fiber U MiniCourses this month.
Reading
OTDR Traces
The second course this month covers one of the topics most
missed on CFOT certification exams - Reading
OTDR Traces. It's all about what elements are
displayed in an OTDR trace and what they represent. It's a
very different format from other Fiber U courses. OTDR
traces are visual, so it's a visual course where you learn
by "pointing and clicking" on a simulated OTDR trace, like
this:

Midspan
Access
As promised last month in our tech article on midspan
access, we took the new material created about Midspan
Access in fiber optic cable installation and
made that into a minicourse. This technique is fairly
widely used because it saves much time and cost in adding
drops to a fiber optic cable, but we've been surprised how
many techs are not familiar with it. The MiniCourse takes
only a little time, about right for a coffee break.

That makes 10 Fiber U MiniCourses, 5 Basics courses, 4
Skills courses, 1 Design course and 6 Applications courses -
26 free online self-study courses for everyone. And we have
lots more planned for the near future.
Here is a list of current Fiber U MiniCourses:
All Fiber U courses are free but there is a
nominal charge for the tests for a Certificate of Completion
to cover the cost of the online testing site we use. Most
online courses cost hundreds or thousands of $US, so we are
sometimes asked how FOA can offer free courses. The answer
is we have very low course development costs since we use
the FOA Guide's pages (almost 1,000 of them) and Videos
(over 100 on YouTube) and the courses are completely
self-study - no instructor to guide you and provide feedback
on your work. (And we do not track you.)
The Fiber U course method has been around for over two
decades and used by tens of thousands of people to
learn more about aspects of fiber optics or prepare for
their FOA certification exams. Since the reference material
for Fiber U is the same as used for training for FOA
certifications and for the certification exams themselves, Fiber
U courses are the ideal study guide for FOA
certifications.
Recruiting
Young Workers - You Can Help!
Our
friend Patrick McLaughlin, editor of Cabling Installation
& Maintenance magazine has an interesting editorial
in the December issue of the magazine. The magazine
has an annual survey of the workers in the information and
communications technology business, what we generally call
premises cabling as opposed to telecommunications or OSP
cabling. In his editorial, he revealed some surprising
statistics:
"More than half the professionals who completed our
survey last year are over the age of 50. Looking again at
our survey results, about 20% of respondents are 60 or
older. ...many may be looking forward to retirement
soon. What I don’t want, though, is for their expertise to
retire with them. I’ve written in this space about the
importance of recruiting a new generation of professionals
to our trade. Pandemic notwithstanding, many construction
trades face the same challenge—convincing young
professionals that this profession provides a promising
career path, and recruiting them into it."
Patrick, that is a very good point and something we at FOA
have been concerned about also. The older practitioners of
our trade have something immensely vital to the industry -
wisdom. Wisdom was once defined to us as "knowledge tempered
by experience, learned over time." For centuries, crafts
have been transferred down generations by apprenticeships
and mentoring, some through formal programs and some through
informal relationships.
Most of us have learned by some training and lots of OJT,
on-the-job-training. Our OJT mentors showed us how to do
things and watched over us to ensure we could do it on our
own. We also learned on our own, often learning from our
mistakes how to do it right, but had someone to call on for
advice.
Our industry's problem is not unique. All trades have
similar problems, caused by the aging of the workforce that
joined the trades 20 to 40 years ago and the mistaken
assumption of young people that they must have a college
degree. All you have to do is read articles how the young
people who believed them are now saddled with college debt
they may never be able to pay off and realize they need
training in a trade to get meaningful employment - just read
the next article!
What can we do? We can all be recruiters to the young people
we know, encouraging them to join our industry where you can
learn a trade while you get paid! Invite them to come to
FOA's Fiber U website and sample all the free online courses
available, starting with the ones that introduce you to
fiber optics like "Fiber
Optics In Communications" and our YouTube Video "Careers
in Fiber Optics."
And please don't forget that fiber optics is a great
opportunity to both sexes. While female fiber techs are only
a small percentage of the workforce, they are some of our
most skillful workers and some of our best instructors.
If you know any guidance counselors, make sure they know our
story too. And FOA has programs that are aimed at high
school and technical college levels where students can learn
fiber optics and premises cabling (remember FOA has a
premises cabling certification that includes copper and
fiber cabling and wireless) and may qualify for
certification by taking the course or by joining the
workforce and gaining experience that is acceptable for
certification.
If you are a contractor interested in recruiting and
training you people through OJT, FOA can help with a
program we are developing. Contact us for more information.
And, thank you Patrick for the nice mention in your editorial
in the December issue of CI&M magazine.
"Thankfully, efforts are underway on many fronts, from
many individuals, to do just this. By naming just a few
I know I’ll miss many, but I want to take this
opportunity to give kudos to people like .... Jim Hayes
and everyone at The Fiber Optic Association..... They
all do praiseworthy work for the industry by educating a
new generation of ICT professional.

people with bachelor’s degrees go back to school to learn
skilled trades
From
Washington Post, November 20, 2020
A lot
of other people also have invested time and money getting
four-year degrees only to return for career and technical
education in fields ranging from firefighting to automation
to nursing, in which jobs are relatively plentiful and
salaries and benefits comparatively good, but which require
faster and far less costly certificates and associate
degrees.
One in 12 students now at community colleges — or more than
940,000 — previously earned a bachelor’s degree, according
to the American Association of Community Colleges. And even
as college and university enrollment overall declines, some
career and technical education programs are reporting growth
— and anticipating more of it.
In some cases, bachelor’s degree holders are obtaining
supplementary skills — computer science majors adding
certificates in cloud technology, for example.
But the trend is also exposing how many high school
graduates almost reflexively go to college without entirely
knowing why, pushed by parents and counselors, only to be
disappointed with the way things turn out — and then having
to start over.
FOA has run several other articles like this in the
last year including the February
issue where we reported about an article in
Fortune Magazine in January 2020
by Jamie Dimon, Chairman and CEO of JPMorgan
Chase Bank. "In the next decade, companies will stop
relying on the outdated notion that you need a four-year
degree to be qualified for a decent job"
The
Value Of Certification
FOA is
defined as a "certifying body." an organization that is
industry-focused to offer certification that attests to an
individual's KSAs, knowledge, skills and abilities. As we
detailed in our July Newsletter the
FOA history, the FOA was founded by industry
leaders and trainers in 1995 to "promote professionalism in
fiber optics through education, certification and
standards." To date, we have certified over 82,234
individuals, most of whom started with our CFOT(tm)
Certified Fiber Optic Technician certification. Also, these
individuals
hold over 110,000 certifications including FOA specialist
certifications.
Certifications are mainly used by individuals to show they
have reached a level of competence in a field. by
employers to evaluate current and prospective employees
and customers to evaluate the competence of a potential
contractor.

There is a new publication, Understanding
Certifications, written by George Washington
University, Corporation for a Skilled Workforce and
WorkCred that thoroughly documents the value of
certifications for all three - workers, employers and
everybody.
Here are some highlights from this extensive report.
Certifications are credentials awarded by certification
bodies—typically nonprofit organizations, professional
associations, industry/trade organizations, or
businesses—based on an individual demonstrating, through
an examination process, that she or he has acquired the
knowledge, skills, and abilities required to perform a
specific occupation or job.
Certifications can offer short-term pathways to
employment. Many certifications can be earned in less time
than a degree, making them a relatively “fast” credential
to earn and a valuable option for working adults and
low-income populations.
Certifications are tuned to rapidly changing labor market
needs. Because many certifications use regularly updated
competency standards based on job analyses, they are able
to stay current in a highly dynamic labor market.
Those who earn certifications and licenses fare better in
the labor market. Two recent studies by Gallup and the
U.S. Bureau of Labor Statistics (BLS) find that someone
who holds a certification and/or a license is more likely
to be employed, earn more, and believe they have a good
job or career compared with someone who does not—at every
educational level. BLS research concludes that a
certification or license carries as much as a 33 percent
wage premium over a high school diploma alone.
Certifications offer employers a tool for skills-based
hiring. At a time when employers will have many choices of
job candidates, use of quality certifications with
transparent competencies as a way of identifying qualified
applicants can provide a means for increasing the pool of
qualified applicants and ensuring a good fit between job
candidates and available positions, as opposed to relying
solely on degrees.
Monthly earnings of individuals with a professional
certification or a license were, on average, $1,057 more
than those with neither type of credential, equivalent to
a 6.2 percent earnings premium associated specifically
with certification
Quality certifications must be well designed, reflect
actual competencies, and let employers and educational
institutions know the holder has a particular, valued set
of skills that can be rewarded with educational credit,
employment, and/or increased earnings.
Ideally, the competencies and standards used for
assessment should be based on an on-going, systematic job
or practice analysis for the occupation. This ensures that
the competencies assessed by the certification and
recertification examinations are updated in a timely basis
and reflect current practice, which ultimately strengthens
the relevance of the certification.
Many of the certifications listing eligibility
requirements have multiple pathways to attain the
requirements, which typically include different
combinations of educational attainment, work experience,
and/or another certification. (FOA: training at an
approved school or Work-To-Cert)
Individuals considering certifications need clear and
easily accessible information about certification
requirements, processes, and outcomes. This transparency
will also increase the likelihood that a certification
will be trusted by employers, a quality which is critical
for individuals looking to improve their economic status.
Many certification bodies offer support for individuals
pursuing their certifications, which can take the form of
online access to reference manuals and/or practice tests.
In some cases, certification bodies approve related
training provided by other organizations. In addition,
certification bodies may form partnerships with
educational institutions or other organizations to provide
training content, study materials, equipment, and other
resources for stand- alone classes as well as classes that
are a part of programs of study and articulated career
pathways. (FOA's Fiber U and online Reference Guide.)

Certifications
For
Colleges and Universities Interested In Certifications
A new
framework to support the development and scaling of
certification-degree pathways has been published by
Workcred – an affiliate of the American National Standards
Institute (ANSI) – in partnership with the Association of
Public and Land-grant Universities (APLU), the Coalition of
Urban Serving Universities (USU), and the University
Professional and Continuing Education Association (UPCEA).
This collaborative, nationwide initiative that culminated in
the development of the framework was made possible by a
grant from Lumina Foundation.
The framework identifies examples, opportunities, benefits,
and challenges associated with integrating industry
certifications into bachelor’s degrees. The framework can be
used by certification bodies and universities to test
different strategies and practices to better align
certification and degree programs.

Will
2021 Be A Year Of Shortages?
Doug
Dawson of CCG Consulting believes that 2021 may be a year
of shortages. He sees the industry as being very busy
right now and expects 2021 to be much busier. As a result,
he sees shortages developing in construction crews,
engineers, components, permitting, funding and more.
"
All
of these potential resource shortages portend problems for
anybody building fiber. It’s hard to imagine a fiber
project of any size that isn’t going to hit by at least a
few of these delays. I’m sure I’ll hear of a few cases
where these delays will be crippling. I think anybody
planning to build fiber needs to anticipate delays and
build them into their schedule because delays cost time,
and time costs money."

BELGIUM’S
FLANDERS IS SECOND EUROPEAN GOVERNMENT TO INTEGRATE VIDEO
GAMES INTO MAINSTREAM EDUCATION
Brussels
- 20 November 2020 -- The Flemish Department of Education
and Training has become the second European government
ministry (after Poland ) to recognise the value of
integrating video games into the classroom, by commissioning
the Game.Learn.Grow toolbox, developed by
Arteveldehogeschool and Mediawijs.
The toolbox serves as a practical guide for both elementary
and high school teachers with over 30 ready-to-use
activities for different age groups, including exploring
ancient Greece in “Assassin’s Creed”, rebuilding their
school in “Minecraft”, lesson sheets and tools for teachers
to create their own video-game-based activities.
Spokesman for the Flemish/Belgian video game sector David
Verbruggen said: “We’re delighted with the
Game.Learn.Grow toolbox and want to thank the Flemish
Department of Education and Training, Arteveldehogeschool,
and Mediawijs for making this possible. Here’s hoping the
tools lead to an ever-expanding database of quality,
game-driven content that prove that games in the classroom
are here to stay.”
ISFE CEO Simon Little said: “It is extremely exciting
to see another European government recognise the value of
video games to education in this way. We know from our Games
in Schools project that video games have an exciting
role to play in the classroom, inspiring an interest in
STEM, equipping students with digital skills, increasing
student engagement and learning outcomes, developing
team-building, problem-solving and mental agility.”
ISFE’s
Games in Schools teachers’ handbook has now been added
to Klascement, the official teachers’ platform in Flanders.
The Flemish Government has also just announced a €100,000
fund to support the Flemish video games sector during the
pandemic. Whilst the sales of video games already on
the market skyrocketed during lockdown – used by players for
education, fitness, entertainment and to stay connected with
friends and family - companies with games still in
development have been impacted by remote working, employee
sickness and much-delayed launches. Flemish Media
Minister Benjamin Dalle referred to the thriving and
innovative games sector in Flanders and the importance of
investing in its video games companies.
This is something FOA is looking at for online and
remote training. The new interactive Fiber U Course Reading
OTDR Traces uses rudimentary interactive game
techniques and we believe more can be done in this
field.
Poor
Net speeds contributing to UK ‘digital divide’
Global
Wireless Solutions (GWS) has released the results of its
latest major study into real-life consumer experiences of
home Internet connections, which uncovers evidence of a
stark ‘digital divide’ in the UK.
As more people come to rely on video for working and
communicating with family, friends and colleagues, nearly a
third (30 per cent) are suffering from inadequate
throughputs – download speeds lower than 2 Mbps or upload
speeds lower than 1 Mbps. Furthermore, according to Ofcom,
speeds higher than 10 Mbps for download and 1 Mbps for
upload is considered a “decent” broadband service; using
this criterion only 64 per cent of homes have “decent”
service.
The extensive study involved GWS testing the speeds of home
Internet connections in over 2,000 households along with
conducting in-depth consumer research into how home Internet
performance has impacted people over the course of the
pandemic. The study primarily involves ISPs, as almost all
(89 per cent) of the homes tested and surveyed use their
home broadband network to connect to the Internet, as
opposed to their mobile network.
The findings from the study suggest that there is a
noticeable ‘digital divide’ in the UK, with inequalities of
home Internet performance impeding some consumers’ abilities
to work and stay ‘connected’ during the ongoing pandemic and
lockdown periods. When connected to their home Internet, 62
per cent of all respondents reported experiencing a range of
issues from being unable to load websites, stream videos or
connect to video conferences. As a result of these problems,
over half (52 per cent) of the respondents claimed they felt
isolated at some point during the first national lockdown.
As the country’s reliance on video conferencing has grown,
people are most likely to worry about network performance on
video or voice calls, as 34 per cent have had problems with
video calling and conferencing over the last few months. But
the data shows that video calling is here to stay, as the
majority of the people in the UK (65 per cent) intend to
continue using video calling platforms after the
technology’s prolific rise this year.

Cost
Of Utility Damages From Excavation in 2019 Around $30
billion
A
recently published report estimates the total cost of
utility damages from excavation in 2019 to around $30
billion. Billion. The DIRT report, published by the
Common Ground Alliance, estimates around 532,000 excavation
damages occurred in the U.S. in 2019, and increase of 4.5%
from 2018.
The report determined failure to notify the one-call center
as the single largest individual root cause, contributing to
29% of damages. Excavating issues made up 29% of damage root
causes, locating issues were responsible for 28% of damages,
and the invalid use of locate requests drove 14% of damages
in 2019.

Fiber
Optic Sources For Transmitters

FOA has
added a new page to its online
reference Guide on laser
and LED sources for fiber optic transmitters. The
types of sources used in fiber optic transmitters are
determined by a number of factors including the speed of
transmission and the distance needed over the link. It's
also tied to the types of fiber being used, affecting
coupling to the fiber and the preferred wavelengths of
transmission. This page in the FOA Guide covers the types of
sources and their characteristics that make them appropriate
for each application.

Standards
Make Us Crazy
FOA
monitors standards activity worldwide and attends
many TIA standards meetings (now virtual) to keep
up with the committees' shenanigans (for non-US
peoples, that word means (according to the
Merriam-Webster Dictionary) a devious trick
used especially for an underhand purpose, tricky
or questionable practices or conduct —usually used
in plural, or high-spirited or mischievous
activity —usually used in plural.) Your editor
(JH) has been involved with US fiber optic
standards since 1983, so we understand the
history, processes and, yes, shenanigans.
We've written extensively in this newsletter about
the games played with dB, changing the definition
so it would be a positive number on an OLTS or
OTDR display, ignoring that this change means that
gain becomes a negative number, going against more
than a century's conventions in technical
measurements of sound, voltage, RF
power
(wireless), etc.
An email from TIA this month included a meeting
report from the last meetings that had this in its
summary of meeting business from the committee
that covers terms and definitions:
TR425-2020-10-14 was reviewed resulting in the
following definitions being accepted without
opposition.
- hybrid
cable: cable that contains both optical
fiber and current carrying members.
- composite
cable: A cable with two or more cable units,
of the same or different media.
In standards, the distinction between hybrid and
composite cables has flipped several times in the
history of fiber optics and differed among
standards bodies. A
hybrid cable originally meant a cable
with two types of fibers, usually MM
and SM, or a hybrid patchcord with,
for example, a SC connector on one end
and LC on the other end. In
the beginning a composite cable was defined per
the US National Electrical Code:
NEC Article 500.8(F) “Optical fiber cable
contains conductors that are capable of carrying
current (composite optical fiber cable)"
More recent standards like the ones
from IECA
(Insulated Cable Engineers
Association) use the term hybrid
for cables with fiber and conductors.
Two examples:
Hybrid Cables and FTTA
cables
The usually reliable Merriam-Webster
Dictionary is no help here, with
several definitions for each word
including:
- Hybrid:
having two different types of
components performing essentially
the same function
- Composite:
made up of distinct parts or
elements
Essentially this is a moot argument -
standards can, and often do, define
things arbitrarily, like dB, and
sometimes don't understand the
confusion they cause. We bring this up
because in the numerous pages of the
FOA Guide, Fiber U and other sections
of the FOA websites, we have generally
stuck by the original definitions
(composite has conductors, hybrid has
two or more types of components) but
note the different definitions used in
some standards. We've been trying for
years now to purge our quizzes, tests
and exams of questions on these terms
because of these inconsistencies.
Please inform us if you find where
we've missed a mention of this issue
in discussing types of cables.
Do any of you call a cable with
SCs on one end and LCs on the
other a "composite cable"???
Midspan
Access - Simplifying Installation Of Drops
Technical
questions we get here at FOA often remind us of things many
of us take for granted that are not known by many installers
and particularly network owners and users. Recently we
received an email like this from a network owner working
with a contractor on a 15mile (25km) cable plant with
roughly 17 locations where cable drops were needed:
"Can the quantity of fiber optic fusion splices and splice
enclosures please be confirmed? For 192F cable, there should
be 194 splices per splice case at each site where a 4F drop
cable is installed."
Neither the user nor his contractor knew about midspan
access. We figured that probably meant that lots of other
people don't know about it either, so we decided to cover it
in this newsletter, add a page to the FOA Guide and maybe
even make a Fiber U MiniCourse about it.
Here is an example:
Many installations involve dropping a small fiber count
cable from a large backbone cable. Backbone cables of
144-288 fibers are common and larger ones are becoming more
common too. Drop cables are often only 2-14 fibers, meaning
most fibers are continuing straight through the drop point.
Midspan access involves opening the cable by removing the
jacket and strength members, opening the buffer tube and
splicing only the fibers being dropped at that point. The
untouched buffer tubes from the opened cable are carefully
rolled up and stored in the same splice closure as the
fibers that will be separated and spliced to a drop cable.

If there is a method of splicing only the 4 drop fibers
instead of the 144 fibers, we will only have 4 splices
instead of 144 or 146 depending on the architecture of our
system. The difference is according to how the drop is
configured.

If you are building a star network where every drop links
back to the origin of the network, you will splice 4 fibers
in the cable to the drop cable, leaving 4 splices on 4
fibers (instead of 144 splices if the backbone cable is cut
and respliced.

If you are building a ring network, you may only be splicing
two fibers going to the drop and two others that are
continuing along the ring network.
All this may seem obvious but in actual practice requires
some knowledge, skills and careful workmanship. To do a
proper job. Fortunately, manufacturers of cables and tools
have good information available online on how to do it, and
FOA Master Instructor Joe Botha has provided FOA with a application
note on how midspan access is done in his classes
also.
The basic process is simple. We will look at a loose tube
cable but processes exist for ribbon cables also. You remove
the jacket of the cable for a specified length according to
the cable type and splice closures used. After removing the
cable jacket, you remove unnecessary strength members,
leaving enough of the stiff central member on both ends to
attach to the splice closure. Identify the tube with the
fibers to be spliced to the drop cable and set aside while
carefully coiling the other tubes for storage in the
closure.
To open the buffer tube, you need a midspan access tube that
shaves off a section of the tube to allow removal of the
fibers without damaging them. Here two types of Miller tools
that shave the tube:

After
shaving the tube and removing the fibers - count carefully
to ensure you remove all the fibers! - you can cut the tube
off to have bare fibers only for the length you need to
splice on the drop cable. All these fibers will be placed in
a splice tray for safe storage but only the fibers being
dropped will be cut and spliced to the drop cable. This is
what the closure will look like, ready for splicing the drop
cable.

In the
case of the particular user who contacted us, not every drop
would use midspan access. His cable plant was 15miles (25km)
long with roughly 17 locations where cable drops were
needed. The cable he was using could only be made in 5km
lengths, so there would have to be several locations where
the cable would be spliced in the 25km run.
The design would need to carefully determine how much cable
was needed along each section of the route, including
lengths for service loops and midspan access or splicing, to
determine which drop points would be using midspan access
ans which would be used as splice points for the entire
cable.
That's why fiber optic network design is important but
sometimes complicated.
Search online for "midspan access" to find lots of
application notes and videos on the subject. Or talk to your
fiber optic cable vendors.

Questions
From FOA Newsletter Readers
December 2020
Are FOA Videos and Web Up To Date?
Q:
Are the videos on YouTube still relevant by today's
standards are are they out of date?
A: Excellent question. We’ve discussed this within
the FOA many times.
For example the live action videos on cable preparation,
termination, mechanical and fusion splicing and testing are
quite old by tech standards but the processes have not
changed in two decades. Preparing loose tube, armored or
tight buffer cables has not changed in over 20 years, nor
has adhesive/polish connector termination.
Prepolished/splice connector and SOC process are different
and those processes have been updated. Testing processes are
the same with the main difference being the automating of
OTDR testing. Manufacturers have dumbed-down OTDRs so well
that it seems few techs know how they work or how to read a
trace, evidenced by the results of the FOA CFOT
Certification exam where questions on OTDRs are the most
often missed.
We just did a review of the copper installation for the
Premises cabling (CPCT Certification) and that has not
really changed in three decades - since the introduction of
Cat 5 cable!
We review and update the technical pages in the FOA Guide
all the time. Look at the Table of Contents (FOA Guide-https://foa.org/tech/ref/contents.html)
and see how many pages have the NEW symbol, indicating
updates in the last couple of months.
Also FOA is adding YouTube videos (https://foa.org/tech/ref/contents.html#YT
) and Fiber U MiniCourses (https://fiberu.org) on many
topics regularly - monthly this year, covering new tech and
the topics we know are lesser-known or new to most techs.
And let us know if there are topics you think we should
focus on in the future.
Microscope Power For Connector Inspection
Q: What
power microscope do you recommend to inspect
singlemode/multimode in 1.25/2.5 format (ST, SC, LC)?
A: Microscopes
in the range of 100-400 power are available. Many people
assume higher power is best - and it is for examining
polishing results in the center of the ferrule - but lower
power helps inspect more of the ferrule for dirt when used
in the field before connecting or testing cables. We prefer
the lower power.
So for patchcord manufacturers, 400, field techs 100.
Patchcord manufacturers will undoubtedly use video
microscopes, most field tech the optical ones.
November 2020
Loss For APC vs UPC Connectors
Q:
I was wondering if there will be a standard connector loss
for a UPC connector and a different lower value for an APC
connector.. ex. upc has 0.5dB while APC is 0.3dB.
I would like to make all connectors uniform on a new network
infra to avoid mismatch and causing any possible damage on
the equipment when APC will be plugged into to a flat.
A: There is really no statistical difference between
APC and UPC connector loss. The lower reflectance of the APC
actually reduces loss since the reflectance represents a
factor in connection loss, This issue of connector grades
has been discussed at international standards committees for
years. ISO/IEC wants to have grades of connectors, rated for
connector loss in ranges from 0.1 to 1dB, but I do not think
it’s standardized. I recommend using 0.3-0.5dB for loss
budgets, where in OSP networks it matters little, since
there are only a few connections and fiber and splice loss
is a larger factor.
Keeping UPC and APC connectors straight is easy - APCs are
Green, UPCs are blue. Everybody just needs to be taught
that!
OTDRs - Launch Cables And Range
Q:
I have a question about OTDR launch cables. In
all readings about OTDR testing, it states that the launch
cable "needs to be of sufficient length ...". What
length is sufficient? How long should a launch cable
be? What is the maximum length of cable plant that can
be tested at one time?
A: OTDR launch cables need to be long enough to allow
the OTDR to settle down after the test pulse leaves the
instrument and reflectance at the output connector overloads
the receiver. The dead zone is a function of the OTDR test
pulse and the condition of the output connector. If you are
testing short cables (<1km) with very short test pulses,
a launch cable can be 20-50m long. If you are testing a very
long cable with very wide pulses (some OTDRs have pulses
~4microseconds long, equivalent to ~1km) you would need a
2-5km launch cable. So the answer to that question is it
depends on how long the fibers are you are testing.
As to how far a OTDR can reach, the answer is generally not
specified in km but in dB. The best OTDRs have a reach of
~40dB at 1550nm which corresponds to ~150-200km, spending on
how good the splices are. That length of fiber would have
~30 splices for say 3dB splice loss.
Here’s the FOA
Guide page on OTDR testing and the FAQs
page Frequently Asked Questions about OTDRs.
October 2020
Last month's article about the installation
of a 6912 fiber cable in small conduit prompted a
number of this month's questions on social media. And there
were more too.
Re: Installation
of a 6912 fiber cable
Q: For this post, "Tight Fit: 6912 Fiber Cable
Pulled in 1.25 inch Conduit”, he asks if they can see one
end completely terminated?
A: It takes about 2 full racks of patch panels or one
rack of splice trays. Sumitomo shows the splicing rack here
https://global-sei.com/data-center-solutions/splicing-rack.html.
Most systems using these cables will buy fully populated
patch panel racks with a splice rack for the cable to splice
to 6912 fibers terminated in the rack.
Q: And a second question:: How long does it take to
terminate? And over how many panels?
A: A very experienced tech can splice one of these
cables in ~75-100 hours using ribbon splicing.
Q: I assume that's smaller fiber like 80 micron
cladding
A: All the fibers in the high fiber count cables are
made with regular singlemode fiber - 9/125micron. TO make
the cables smaller, the buffer coating diameter is reduced
to ~200microns to make the fibers smaller.
Q: How was it prepared with the splice tray and ODF?
It might require a dedicated panel and splice tray.
A: It takes about 2 full racks of patch panels or one
rack of splice trays. Most systems using these cables will
buy fully populated patch panel racks with a splice rack for
the cable to splice to 6912 fibers terminated in the rack.
Q: Is this an actual photo or was the cable installed
in a different type conduit.
A: We were told that is the actual size of the cable
and conduit although not of the actual installation
discussed.
Q: What is the minimum bend radius of that cable?
What procedures did they use to maintain that bend radius
through those 90 degree curves?
A: The minimum bend radius is 15X the cable diameter
for that cable (diameter 1.14” or 29mm), about 17” or
435mm. The conduit bends had to be controlled to be larger
than that radius.
Jobs In The Movie Industry
Q: Does anyone know if there are job positions in the
film industry that involve fiber optics? I started out
working in film with audio work with some camera as well. I
eventually transitioned into fiber optics installation and
testing. I've been trying to find out if there's a way to
find work that combines the two.
A: There are certainly jobs for fiber techs at the
film studios. We worked with a group 20 years ago to find
dark fiber in LA to connect studios to sound stages and
other facilities. Every studio now has fiber connections
everywhere, like this one at Paramount (below). I don’t know
where to look for jobs, but I’d guess it would be through
the unions - who represents the techs for the cameras,
monitors, etc.?

Preparing Cable For Splicing
Q: Is there any standard on the preparation length of
strip jacket upto the splice tray. Ideally its better to
have a loop of buffer before getting into the tray if ever
the closure has enough space for slack.. its also nice to
put some hose to the buffer to add on protection. So far, i
don't see any standard and can't support the remarks on what
to follow. The practice was to take note on macrobend and
have enough length of fiber to reach the machine.
A: There is a lot of variation in the size, shape
and design of splice closures, so the length varies
according to the closure and trays. For loose tube cable,
the length of buffer tube from the entrance to the splice
tray and the length of fiber needed in the tray are given in
the directions for that splice tray. Similarly for ribbon
cable, but the variations in ribbon cable designs often
requires special handling and sleeving for the ribbons. Most
manufacturers have specs available online.
Fusion Splice-On Connectors (SOCs) (From an FOA
Instructor)
Q: A question came up from one of our students
regarding splice on connectors. Is there a TIA or
other standards body that addresses this issue? We are used
to the 0.75 dB loss for a mated pair, however, when this
mated pair has two fusion splices that terminate the
connector, is there a recommendation?
One could make the argument that it does not make any
difference as the other alternative is splicing a pigtail
for termination of a cable. This pigtail splice is
normally included in the link loss budget
calculation. So similarly, with a splice on
connector it is the same as splicing on a pigtail.
A: There are no specific TIA or IEC specs that
address these splice-on connectors or pigtails. If you used
TIA numbers and included the splice and connector it would
be 1.05dB - 0.75dB for the connection and 0.3dB for the
splice, that’s mated to a factory adhesive/polish
connector. Or if it were two similar connectors,
1.35dB.
Everybody, including the people in TIA standards groups,
know those numbers are too high for most single ferrule
connectors. They keep them at 0.75dB for prepolished/splice
connectors (w/ mechanical splices) and array connectors
(MPOs) which have somewhat unpredictable performance.
Internationally, IEC has created grades of connectors from
~0.3 to over 1dB. The newer mechanical splice connector kits
now use the Chinese copied cleavers which are super - at
least the few we have tested - and the connectors are now
much lower loss and consistent.
SOCs (fusion splice-on connectors) are spec’ed as the total
termination and are generally just as good as the typical
adhesive polish connector - 0.5dB is plenty of margin for a
those mated to a factory adhesive/polish connector.
Spliced on pigtails are generally considered a termination
and the splice is not broken out - like a long SOC. But I
cannot guarantee everybody thinks that way. But a fusion
splice is typically <0.1dB anyway.

The
word on the "Dig Once" program is getting out - FOA is
getting calls from cities asking us for information and
advice. Here are some links:

Fiber Optic Cable Plant - The Finished Product 4/2020
In
April, FOA received inquiries from several sources that all
deal with the same subject - what is involved in the
specification and acceptance of a cable plant at the end of
a installation project. And what are reasonable
specifications for a cable plant.
FOA has a lot of documentation on a project involving
designing and installing a cable plant in the
FOA Online Guide and our Textbooks, but the acceptance
process has usually been relegated to a few paragraphs. We
decided to add a page
on project "Deliverables" in the FOA Guide that covers
this topic in more depth. This page looks at a project, goes
into some depth on loss budgets and includes links to FOA
tech documents to help you investigate further.
Correction: In the article, the original list of fiber
specs for G.652 was wrong. It should be 0.4dB/km @ 1310nm.

Is
There A Standard For Fiber Optic Installation?
Another
question we get often is "Is there a standard for fiber
optic installation." The answer is yes, but not from the
usual standards groups you might expect. Over 20 years ago,
the National Electrical Contractors Association (NECA) asked
FOA to help create a standard for installation. That
standard, ANSI/NECA/FOA-301 has been updated three times
already and is about ready for another update.
Unlike most of those groups who charge you a fortune for
standards, FOA covers the cost so ANSI/NECA/FOA-301
is available free from FOA.

What
Fiber Techs Don't Know -
What
We Learn From FOA Certification Tests
As FOA
moves more testing over to our digital online testing system
at ClassMarker, we have access to more data about our
testing, including what questions and topics on the tests
are answered incorrectly most often. Having this data gives
us an opportunity to evaluate the questions and how they are
stated, but more importantly it allow us to help our
instructors teach the subjects and us to change our
curriculum and online courses to emphasize these particular
topics. These are some of the topics that we have noticed
are answered incorrectly more often in FOA and Fiber U
tests.
Most of the questions missed are on testing.
1. OTDRs - particularly what information is in the OTDR
trace.
2. The difference between dB and dBm
3. Loss budgets - both the concepts and doing the math
4. Insertion loss testing - single-ended or double ended for
testing patchcords or cable plants, how to set 0dB
references
5. Units of measure - fiber is measured in microns,
wavelengths in nanometers, etc.
At FOA, we're working to add Fiber U
MiniCourses on these topics and working with our
schools to emphasize these topics in their classes.
If you are going to be taking a FOA certification course or
test in the near future, these topics should be on your
final exam study list.
What We Learn From Hands On Labs
We learn about students performance in hands-on labs from
the feedback of our instructors and our own experiences too.
One big problem is the use of hand tools. Growing up today,
you learn how to use keyboards, mouses and touch screens,
but decades ago, you also learned how to use basic hand
tools. This is big enough of a problem that we're
considering adding some video lessons on basic hand tools to
prepare students for cable prep, termination and splicing
that require the use of hand tools.
FOA
"Work-To-Cert" Program
Experience
Plus Online Study At Fiber U = FOA Certification
This
year, more techs have become comfortable with online
conferences, webinars and training. Many have discovered
that they can become FOA Certified using their experience in
fiber optics and study for the FOA certification exams
online at Fiber U.
Thousands
of industry professionals have applied to the FOA directly
for certification without the need for classroom training,
based on their knowledge and skills developed working the
field. Since FOA certifications are based on KSAs
(knowledge, skills and abilities), current techs already
show the skills and abilities required through their field
experience. FOA provides free online self-study
courses at Fiber U
for the knowledge part to prepare you for FOA certification
exams which you can also take online.
If you are an experienced field tech interested in
certification, and FOA is the internationally
recognized certifying body for fiber optics, you can find
out more about the FOA
"Work to Cert" program here.
If you are already a CFOT, FOA also offers many specialist
certifications you can obtain based on your experience as a
field tech. See what's available at Fiber
U.

For Training Classes - Outdoors (11/2020)

Tom
Collins, Techtricians, FOA Director, keeps exploring new
ideas for training. This time, the course moved outdoors in
Daytona Beach, Florida. This solution works well as long as
it's warm and dry!
New
Approach To Fiber Optic Labs - Sharing Test Equipment
(10/2020)
Tom
Collins, Techtricians, FOA Director
Techtricians,
a FOA approved school, has taken a new approach in
how we provide lab training. Fifteen years ago, we developed
a hybrid training model had the participants complete online
(remote) lessons with face to face labs. Over the past 12
years trade organizations, colleges, vocational, vendor
training, and trade apprenticeships have adopted this model.
At the beginning of the pandemic we spent a lot of time,
energy, and money developing remote labs. We have
incorporated lessons learned from that process to restart
safe face to face labs.
First, we provide disposable materials and PPE’s for all
learning. Every student has their own work space with 8-9
feet of separation and their own set of hand tools only used
by the student. All of the classroom information is accessed
online or with USB drives. Our biggest challenge was how to
safely share testing equipment so every student could have
the practical hands on experience.
We believe we have found that solution with the help of “ezremote”.
The ezremote allows a multitude of students to have
practical exposure and experience with using a video
microscope, OLTS and OTDR testers. Every student can access
the remote via their own iPad or their smart phone, see
below picture and movie.

The VeEX OTDR set up for remote access in class
Recently, we contacted PCS, Inc. which is a premiere
manufacturer’s representative firm serving the Southeastern
US since 1974. Headquartered in Roswell, GA, Marc
Wright a sales representative spent a lot of time and
energy helping Techtricians to purchase the VeEX
FX150+ device. It is a full featured Mini OTDR with
high resolution sampling and intelligent link mapping for
Metro, Access and FTTx networks remote application. The
compact, lightweight platform incorporates built in WiFi,
power meter, light source, fiber inspection probe and VFL
test options which add exceptional versatility to the unit.

The remote OTDR displayed on an iPad (L) and on 4
smartphones and 2 laptops
In September we completed our first trial in a face to face
lab session in Lake Mary, Florida. The OTDR unit uses a WIFI
connection. The students went to the VeEX website with their
iPad or their smart phone and connected the to the base
unit. The lab module used one OTDR setup for the entire
class for testing the cable plant.

The instructor's laptop is connected to the OTDR and
projecting the display for everyone to see
The students when logged-in had control over the OTDR. Each
student saw the same screen which made the various events
much easier to explain. The module is very safe as the OTDR
is not touched by any student. The feedback we received from
the students was very positive. They provided suggestions
for future training modules. Even after the pandemic is
over, we will continue to use this new training method. Our
best teachers are our students and our hats are off to all
of our students.

DIY (Do-It-Yourself) Labs (6/20)
Knowledge
is easy to get online, but learning skills requires
"hands-on" practice and that requires tools and
components to practice with. Here at FOA, we've been
working on an online course that could help many
techs learn new skills or improve others using an
online self-study course and their own equipment. Recently,
we have updated the materials in the Fiber
U Fiber Optics Basic
Skills Labs which includes cable
preparation, splicing, termination and testing.
And we have created a Basic
Skills Labs - Copper Premises Cabling to
cover UTP (Cat 5) and coax copper cable
processes. As with all Fiber U courses, these
are free.
Several times in the FOA Newsletter we've discussed
the Fiber
U Basic Skills Lab. This online DIY lab course
assumes you have your own equipment to use for the
labs, but most novices, unless they work for a larger
company already in fiber optics, will not have
equipment. FOA instructors have found a solution:
purchase inexpensive equipment online. What they have
found are many low cost tools and components that are
perfectly suited to training.
If
you do not have tools or equipment and want to
purchase them, there is a new
Fiber U DIY Basic Skills Lab lesson with
directions on how to purchase inexpensive tools
online and use them to learn basic fiber optic
skills. Those tools and components are what we
describe here.
For example, you need a fiber cleaver
for splices and prepolished/splice connectors. A good
cleave is essential for a good splice or termination
with a splice-type connection. Good cleavers are now
available online at prices in the US starting at
$20US.
Besides the cleaver, another really good tool for
learning or teaching is a visual fault locator. These
devices used to be very expensive, but now are
available online for $10-20.
Many online sellers offer sets of fiber optic tools in
a kit for very low cost.
With plenty of tools available online, the next things
you need are components to practice on. No problem
here either. You need a patchcord, some mechanical
splices and some prepolished/splice connectors. The
connectors and splices are available from online
sellers for ~$1 each, easy to afford plenty to
practice on.
FOA has used all these available parts together into a
do-it-yourself
hands-on lab as part of the Fiber U Basic Skills
Lab. You can do this yourself at a very low
cost. We
even provide directions on how to search for
suppliers of these tools and components.
Caution!
FOA has not exhaustively tested these tools or
components enough to recommend them for field use. The
work we did with them to create teaching labs shows
they are certainly good enough to use for teaching the
installation processes in a training lab. We suggest
read the buyers reviews and do some of your own
testing before using them for anything other than
training and practice.
FOA
Guide "Basics Of Fiber Optics" Now Available Online in
Portuguese (6/2020)

FOA has
now translated the Basics of Fiber Optics textbook in our
Online Guide into Portuguese, joining Spanish and French
translations. For those speaking Portuguese, we have the
technical information and for schools we also have
curriculum available.
Here
is the FOA
Guide in Portuguese,
Spanish and
French
translations.
Time
To Learn - Online - (Update 4/5/6/8 2020)
Schools
have generally been closed during the pandemic lock-downs,
so FOA has been working with some of them to create new
online learning experiences that can in some cases lead to
certification online. FOA certifications are still based on
the KSAs - knowledge from the classroom, skills from the
labs and abilities judged by instructors or proven by actual
experience.
ZOOMing
Much of what we're doing benefits from the capabilities of
"Zoom." Others have created videoconferencing apps, but none
work so well, especially with limited bandwidth. We've seen
remote labs that have an instructor showing students how to
use the tools they were sent then watching them duplicate
their actions. We have worked out methods to use Zoom to
proctor FOA's online certification exams.
Blended
Learning
While most FOA schools have suspended in-person training
during this period, some are offering a "blended
learning" option. That means that students sign up for a
FOA certification course, take the classroom sessions on
Fiber U with the assistance of a FOA certified
instructor. Now online instruction can include reviewing
the labs using the Fiber
U Basic Skills Labs, then when it's possible to attend
classes at the school, complete the hands-on labs and
take the FOA certification exam.
Online Remote Labs
Alternatively, some schools are experimenting with
"remote labs," where the students get sent tool kits
and components and labs are conducted by
videoconferencing. Before the labs, the students may
watch demos by their instructor on videoconferencing
and/or review the relevant "virtual hands-on" lessons
in the Fiber U Fiber
Optics Basic
Skills Labs so they will already know
the steps in the exercises. And
Fiber U has the new
Fiber U DIY Basic Skills Lab lesson
with directions on how to purchase
inexpensive tools online and use them
to learn basic fiber optic skills. Videoconferencing
allows the instructor to remotely monitor their
work and provide help as needed. Contact
the FOA for more information.

FOA Zoom Exam Proctoring
Online
Certification Testing
FOA has all its certification tests available
online, both for use by our schools and by our
direct "Work
to Cert" applicants. All FOA certification
tests require a proctor to oversee the applicant
taking the exam. In this time of social
distancing, getting a proctor can be difficult, so
FOA now has procedures for online proctors
administering the exam. Contact
the FOA for more information.
OJT - On-The-Job-Training
Many novices get a job and learn on the job. They
usually have an experienced tech who helps them gain the
knowledge and learn the skills they need to
perform their job. Thinking about this in relation to
the
FOA KSAs, the knowledge, skills and
abilities needed by a fiber optic tech, the tech
will learn skills but not the basic knowledge that helps
them understand the processes involved. FOA can offer
help here, using our Fiber
U online self-study programs. While the tech
learns on the job, they become a Fiber
U trainee, getting the knowledge they need,
while working under their "mentor" at work. This is
particularly good for contracting companies who need
techs but do not have the usual training courses
available. Interested in OJT programs? Contact FOA
for more information.
Can
You Learn Hands-On Skills Online?

Knowledge is easy to learn online, but learning skills
requires "hands-on" practice and that requires tools and
components to practice with. Here at FOA, we've been working
on an online course that could help many techs learn new
skills or improve others using an online self-study course
and their own equipment. Recently,
we have updated the materials in the Fiber
U Fiber Optics Basic
Skills Labs which includes cable preparation,
splicing, termination and testing. And we have created a
Basic
Skills Labs - Copper Premises Cabling to cover
UTP (Cat 5) and coax copper cable processes. As with
all Fiber U courses, these are free.

FOA offers free online self-study programs at Fiber
U. Many users are preparing for FOA certification
programs - taking courses at our schools or using the "Work-to-Cert"
program. Some of our schools are requiring Fiber U programs
as prerequisites for their classroom courses so they can
spend more time on hands-on activities.
