Example: FTTH Is A Good Investment
This
announcement shows that some investors believe that FTTH
is a good investment. We hope more investors get
involved in helping connect areas that are unserved or
underserved.
Race
Communications Announces Partnership with Oak Hill
Capital
Oak Hill Capital has entered into a definitive agreement
to make a majority investment in Race Communications. Bank
Street served as exclusive financial advisor to Race in
connection with the transaction, marking our 16th
announced deal in the Communications Infrastructure &
Services sector year-to-date in 2020.
· Race
Communications is a fiber-to-the-premises (FTTP) operator
serving homes and small businesses as well as enterprise
and institutional customers across the state of
California.
· The company's
all-fiber network passes ~22,000 locations and serves
~10,000 customers in the Sacramento, Bay Area, Sierra,
Central Valley, Los Angeles and San Diego regions.
· Race focuses
on unserved and underserved communities in secondary,
tertiary and rural markets in which it can address unmet
customer needs for gigabit broadband internet access.
· The company's
partnership with Oak Hill will enable Race to accelerate
the expansion of its fiber network throughout the region
as it looks to address the digital divide.
· Oak Hill's
partners are highly experienced in the FTTP sector and
will add value to the Race team based on their experience
with other platforms such as MetroNet and Vexus Fiber.
· The investment
in Race is the 10th financial sponsor investment in a U.S.
FTTP provider announced year-to-date in 2020 across a
number of different deployment strategies.
The Race transaction amid all of the other recent activity
underscores the strong investor enthusiasm for the FTTP
asset class that is increasingly being viewed as a
generational opportunity to address the ~100 million U.S.
homes that do not have a fiber connection today.
Race

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.

New Fiber U MiniCourse - Media Conversion

Got
An Hour Or Less? Learn Something New About Fiber Optics.

Fiber Optic Media Conversion

Electronic
devices communicate internally using electrons on
conductors and communicate with other devices using copper
cables. radio waves (wireless) or fiber optics. These
often require connections into fiber optic networks since
fiber optics is the backbone of the world's
communications. This
course describes these converters and how to use
them. You

Installation
Tech
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.

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

Tight
Fit: 6912 Fiber Cable Pulled in 1.25 inch Conduit
(September 2020)
Furukawa
Electric Co., Ltd. (FEC) conducted an experiment in its Mie,
Japan facility to demonstrate the installation of a
6912-fiber optic cable with an outer diameter of 1.14 inches
(29 mm) in a 696 foot (200m) long conduit with three 90
degree curves and an inner diameter of 32mm. The conduit
used was a standard product installed in conventional data
center campuses. Engineers confirmed a maximum pulling
tension of 84 pounds (372N), well below the maximum pulling
tension of 600 pounds (2700N) specified for the cable.

The cable was installed in a 1.25 inch (32mm) conduit with a
maximum length of 1,411 feet (430m) in a North American data
center campus in 2020 to support live traffic. The high fill
ratio in this application is not typically recommended for
Outside Plant (OSP) cable installation. However, in this
application, the end-user was willing to accept the
installation risk in return for maximum fiber density. The
installation demonstrated that FEC’s 6912 fiber optic cable
can be successfully installed into 1.25 inch (32mm) conduit
using appropriate tools, work procedures, and optimum
installation conditions.
“The FEC 6912 fiber optic cable at least doubled the fiber
count possible in a 1.25 inch conduit, compared to competing
available designs,” said Ichiro Kobayashi, General Manager
of optical fiber & cable engineering department, FEC.

New
Study Shows State Barriers to Community Networks Decrease
Broadband Availability - Community
Networks. (September 2020)
That
community networks act as a positive force in the broadband
market is something we’ve covered for the better part of a
decade, but a new study out in the journal
Telecommunications Policy adds additional weight (along with
lots of graphs and tables) which shows that states which
enact barriers to entry for municipalities and cooperatives
do their residents a serious disservice.
“State
Broadband Policy: Impacts on Availability” by Brian
Whitacre (Oklahoma State University) and Robert Gallardo
(Purdue University), out in the most recent issue of the
journal, demonstrates that enacting effective state policies
have a significant and undeniable impact on the pace of
basic broadband expansion in both rural and urban areas, as
well as speed investment in fiber across the United States.
The authors zero in on three particular policies that they
say have among the most significant impact on whether a
community has broadband or not: whether or not the state has
passed laws restricting municipalities and cooperatives from
building and operating broadband networks; whether or not
the state has a broadband office devoted to expansion and
staffed by full-time employees; and whether or not the state
has a funding program dedicated to expanding broadband
networks. Each of the above is considered against general
broadband availability at the national level, but also for
counties classified as rural.

Questions
From FOA Newsletter Readers
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.

Fiber Optic Regulations for Cable Markers
Q: I
wanted to inquire on any federal regulations there may be on
Cable Markers to alert citizens of fiber optic conduit
underneath the ground. We have had conflicts with installers
placing vertical white and orange markers in right-of-way in
residential areas
A: (Fron
Scott Landes, Rhino
Markers and
dp-PRO magazine) There are no regulations on
communications markers. Gas/Oil pipelines must be marked and
there are specifications for those markers. Curb markers can
be effective in residential areas. However they often do not
have a warning message telling people to call 811. They are
not as effective as marker posts, but if they are used along
with soil markers, which can be mowed over, you can create
an effective system.
Replace Coax With FIber
Q: I
read some of your interesting articles on network upgrades
and I was wondering if you can spare some suggestions.
I might be able to purchase an old non-pressurized
underground coaxial network, basically an old coaxial cable
inside a conduit. Is there any ‘cheap’ way to replace the
old coaxial cable with a new optic fiber cable, perhaps
simultaneously pulling out the old coaxial cable and pulling
a new fiber tube inside the old conduit?
A: If you own the conduit, it should be relatively
easy to remove the coax and replace it with fiber optics.
Our advice would be to pull the coax, pulling in a pull tape
as it is pulled out, clear the conduit and pull in the
largest microduct assembly you can - 6-7 12mm ducts is
usually only 40-50mm in diameter. Then you can blow in a
number of microcables. A 288 fiber cable in each duct adds
up to a lot of fiber or a lot of leasing to service
providers.
We also ran an article in a FOA
Newsletter "New Way To Install Fiber In Old Coax” that
describes how to replace the center conductor and dielectric
of the coax with fiber.
Testing Bare Fiber
Q:
I was wondering if there’s an equipment for a visual
fault locator but on a bare fiber cable. I know there’s a
bunch of VFL that needs an ST connector or LC connector to
use. I’m just wondering if there’s one for bare.
A: You can get a gadget called a “bare fiber adapter”
that allows you to strip the fiber, cleave it and clamp it
in a connector - then attach to a VFL or other source. If
you only have short lengths of fiber, you can probably get
by without cleaving the fiber as enough light will be
captured with a broken fiber.

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.

For Training Classes - Outdoors (11/2020)

Tom

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.
For more information, contact Tom or Donna Collins at Techtricians.
New
Fiber U MiniCourses (September 2020)
Got
An Hour? Learn Something New About Fiber Optics.
Online
learning has been growing even more popular during the
pandemic, and FOA's Fiber U free online courses have
certainly been popular. We've just introduced a new type of
short course, one you can finish in an hour or less, that
covers a specific topic. The topics were easy to pick; they
are ones we're asked about often.
The courses have two components, video lectures and
readings, that are complementary. As usual there is a
self-test to allow you to check your comprehension. As with
other Fiber U courses if you desire, you can take a short
test for a Fiber U Certificate of Completion that costs
only $10.
The three new courses now available are "Fiber Optic
Restoration,' Connector Identification" and "The
Mysterious dB of Fiber Optics."

Fiber
Optic Network Restoration MiniCourse.
Every
fiber optic network is susceptible to outages, either by
damage to the cable plant or problems with the
communications equipment. This Fiber U MiniCourse covers
what kinds of damage occurs to a fiber optic
communications network, how to plan for outages and
restoration and how to troubleshoot and repair problems.
This course is aimed at managers and network owners as
well as contractors and installers.
If you are interested in restoration - aren't we all?
- you should also read this article in dpPro magazine

Fiber
Optic Connector Identification MiniCourse
Over
the history of fiber optics, there have been more than 100
unique designs for fiber optic connectors. Fortunately
only a few have become widely used, but field techs often
encounter connectors they are not familiar with and call
FOA for help. This Fiber U MiniCourse covers the most
popular connectors today and some that have been widely
used in the past that techs often contact FOA asking for
help in identifying them.

The
Mysterious dB of Fiber Optics MiniCourse
Fiber optic measurements of power
and loss are made in dB, a mysterious unit of
measurement that confuses many people. This
MiniCourse helps you understand what dB and dBm are,
how they are defined and measured. The course also
explains how small change in an international
standard created confusion and misunderstanding of
dB. Even if you aren't a math whiz, this FOA
MiniCourse can help you understand dB.

Director and instructor Tom Collins sent photos of his
recent IMSA/FOA CFOT class held in Florida. It shows how Tom
dresses for the job and how his students are social
distancing. More FOA classes are being held now using
techniques like these.

Training
Is Back - Made Safer (6/2020)
FOA
schools are starting to offer classes at their facilities
again to provide the personal interaction with an instructor
and hands-on labs, but some things have changed to provide
social distancing. Serge Rodrigue at Fibre
Zone in Quebec, Canada sent photos of his new lab
setup that includes individual lab stations with plexiglass
barriers.

Students are following safe working protocols - masks and
gloves - to make classes safe and meet local government
requirements for social distancing.

Contact Fibre
Zone in Quebec, Canada for
more information on their classes.
FiberNext in New Hampshire has also rearranged classrooms
for safer classes and has begun training in their facilities
in Concord, NH.

Contact FiberNext
in Concord, NH, USA or
more information on their classes. Also ask about joining
their CFOT
Club for savings on products and training.
Fiber
Optic Training Online - Simulations and Do-It-Yourself
Hands-On Training (6/20)
Simulating
Optical Loss Testing
FOA has been experimenting with simulations,
especially for testing since test equipment is
generally not inexpensive and requires a selection of
cables for reference test cables and cables to test.
We have had an OTDR Simulator based on the software
for an OTDR and a selection of traces for analysis.
Now we've created an optical loss simulator that uses
some web programming to allow stepping through the
process of setting up and testing a cable with a light
source and power meter.

The simulation provides virtual meter and source,
inspection microscope, cleaners and a selection of
cables needed for testing. In the animation above you
can see one of the user interactions - the student
must use the proper button to set the "0dB" reference.
The loss simulator also requires the student use the FOA
Loss Budget Calculator to calculate the expected
loss of a cable under test, compare it to the measured
loss and make a Go/NoGo decision.
We even provide two versions of the simulator -
singlemode and multimode. The singlemode version tests
an OSP cable and then has the student compare OTDR
traces to troubleshoot problems. The multimode version
shows the effects of modal conditioning on multimode
measurements.
At the end, we've even added a wrap-up of the
techniques of loss testing and a quiz.
We added the loss simulator in the new Fiber
U DIY Basic Skills Lab for a virtual hands-on
testing lab.
Check out the FOA
Insertion Loss Simulator here.
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 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.

finally troubleshooting and repairing a network
outage. Lecture 54 is a short history of the
development of fiber optic connectors and a
overview of the ones most used today. Lecture 55
will teach you about dB, it's origin, an
explanation of the math behind it and why
standards can make it confusing. Lecture 56
explains fiber optic cable bend radius limits and
reduces the confusion over radius and diameter.
Lecture 57 is a quick tutorial on cleaning and
inspecting connectors. Lecture 58 is about
converting fiber to copper or multimode to
singlemode fiber.

and easy to understand.
FOA
Loss Budget Calculator On A Web Page 5/2020
FOA has
written many articles about loss budgets, something everyone
involved in fiber optics needs to know and needs to know how
to calculate. We recently discovered how to get a
spreadsheet ported to a Web page, so we created this web
page that calculates loss budgets. We have an iOS loss
budget app, but with this web page, you can calculate loss
budgets from any device, smart phone, tablet, laptop, or
desktop computer that has web browsing capability.
