We were going to cover several more topics this month, the
future for 10G PONs for FTTH, 5G indoors, cabling for data

downloaded or received in the mail literature on all these
topics during the month.

ORIGINAL Article: March 2019
FOA has recently gotten several inquires about these new high
fiber count cables - 1728, 3456 or even 6,912 fibers. Like
this one from Prysmian with 1728 fibers:
We've been looking for directions on how to deal with high fiber
count cables. Several contractors tell us ribbon splicing is the
way to go, and most of these cables now use a version of the new
ribbon types that are flexible. We've put together this
table from some articles on splicing ribbons:
Is that realistic? We've heard the flexible ribbons may take
twice as long as the conventional ribbons.

Guide Adds And Updates More Pages
Jargon, Restoration, Fiber Characterization And Management
Guide is a living thing, growing bigger and better
continuously, updated for new technology and techniques, aimed
at keeping the world up to date on fiber optics and cabling. In
the last month alone, the Guide has added three new sections you
should find interesting, informative and helpful and updated a
Optic Jargon - Illustrated
always believed that jargon is important - it's the language we
use - and fiber optics has a lot of its own language. As you
have probably noticed, Chapter 2 in all our textbooks is
"Jargon." That chapter gives an introduction to the language and
helps get the reader familiar with the terminology before they
delve into the rest of the book. This month, we updated all the
jargon pages to include dozens more photos and drawings -
animations too - that make it even easier to understand fiber
optic jargon. Take a look at Basic
Fiber Optic Jargon, OSP

networks are susceptible to problems that affect
communications. A consequence of fiber optic systems’ high
bandwidth, long distance capability and security is the
extreme dependence of users on the non-stop operation of
these systems. They can transmit large amounts of data long
distances with immunity from signal degradation and
extremely high reliability, so these systems usually carry
the most critical data. If something happens, it’s important
to not panic. You should have a plan, components set aside
for repair and knowledgeable people on stall or a contractor
on call. When you design the network, restoration planning
should be part of the design. If you did not do that, now is
the time to do it before something happens. FOA
has a new page on Restoration in the FOA Guide that
provides advice for everyone - contractors/installers,
network owners and managers - everybody who gets involved
when the network goes down.
get faster and link spans get longer, fiber characterization
becomes more important to he network owner and
contractor/installer. Chromatic dispersion, the dispersion
caused by light of different wavelengths, and polarization mode
dispersion, caused by the polarization of the light in the
fiber, become factors limiting the bandwidth capacity of fiber
links. Pulse broadening due to dispersion and the variation of
fiber attenuation with wavelength can become issues with DWDM.
All these factors need testing on long distance networks to
ensure proper link performance. Tests are performed on new
installations to ensure the fiber being installed is capable of
future upgrades. Older cable plants are tested to evaluate
fibers for upgrades of legacy communications systems at slower
speeds. We've created a certification program for fiber
characterization, CFOS/FC, but not many FOA schools have the
equipment to teach the course. In addition, we've had requests
for a course for managers, not technicians, who don't need to
know how to perform all the tests but do need to know what the
problems are, what fiber links need testing and how to find
competent contractors to do the work. The updated Fiber
Characterization page in the FOA Guide goes in to more
depth on why fiber
characterization is important, what tests need performing and
how to interpret results.
every page in the section of the FOA Guide on Fiber Optic
Testing has been reviewed and updated, much of it based on the
new FOA textbook on testing. This includes pages on measuring
power, fiber attenuation, connector or splice loss and cable
plant loss. Browse
through the testing section and see what's new.
Optics For Managers
the FOA, as part of the fiber optic industry and especially in
our role as educators, most of our focus has been training the
designers and installers of fiber optic cable plants and
networks. But what about the people for whom they work or
build the networks? What do network managers, project
network owners, IT personnel, facilities managers, network
designers, estimators, inspectors, etc. need to know about
fiber optics to ensure the success of their project?
has been working with several groups to develop educational
programs for managers. We've started with a page in the FOA
Guide on Fiber
Optic Network Management that describes what our advisors
think is important and created a page to introduce them to the
language and technology of fiber optics which we call "Fiber
Optic Jargon - Illustrated." Over time, we'll be expanding
this section and create a Fiber U self-study course also.
FOA Guide to OSP Construction
created a new section of the FOA
Guide on OSP
Construction. We've expanded some sections to
include more on cable pulling, blowing and aerial construction
with lashed and ADSS cables. The FOA has extensive material
available in our textbooks and online FOA Guide on what is
involved in the fiber installation process (cable installation,
preparation, splicing, termination and testing), so consider
this the textbook for the construction processes that occur
before the typical FOA CFOT-certified techs begin their work.
Included in this new Guide is comprehensive information on new
techniques like air-blown cables using microcables and
microducts. It also covers aerial cable installation more
thoroughly than is typically found in websites or literature.
The audience for this new section of the FOA Guide includes the
management of organizations owning or installing fiber optic
cable plants, designers or estimators of the cable plant, as
well as the actual CFOT certified techs doing the installation
work. It is intended to provide background information on the
entire project and in conjunction with the other FOA information
on basic fiber, OSP fiber, design and testing, provide complete
information on all stages of a fiber optic communications

killed, nine injured, and three buildings destroyed in
downtown Sun Prairie, Wis.
A hole punched into a 4-in.-dia gas pipeline during
fiber-optic line laying is blamed for an explosion that killed a
34-year-old fire captain and injured nine other people,
including four firefighters, in downtown Sun Prairie, Wis., on
July 10. The injured were treated at nearby hospitals and have
since been released. The blast destroyed three buildings,
including the Barr House, a tavern at 100 Main St. that was
owned by the deceased fire captain, Cory Barr.
Sun Prairie Fire Chief Chris Garrison said at a news conference
that after the leak was initially reported at 6:20 PM CDT, first
responders established a 300-ft-dia "hot zone" in the area and
evacuated about 65 people before the explosion occurred. "The
rapid response of firefighters, EMS and police saved a lot of
lives," Garrison said. "This could have been a lot more tragic
than it was."
The owner of the fiber-optics network is Verizon Wireless, which
confirmed in a statement that it had contracted with Bear
Communications "to provide a fiber backhaul for our networks."
It added that no Verizon employees were present at the job site.
"Verizon does contract with local providers in various markets
to provide fiber backhaul for our networks," the Verizon
statement said. "While we have not been contacted about the
investigation, both we and Bear are prepared to work with law
enforcement, public safety and public officials as they

FOA is a
non-profit professional society chartered to promote
professionalism in fiber optics through education, certification
and standards. FOA is mostly known for certifying techs -
-Certified Fiber Optic Technicians - but also may be CPCTs -
Certified Premises Cabling Technicians or corporate
members involved in fiber optics.
FOA is a "virtual organization" - we have no "brick and mortar"
presence. We operate over the Internet with operations centered
in California, with active workers and volunteers in locations
as diverse as Texas, Ohio, Canada, Singapore, Malaysia, Denmark,
South Africa, the Middle East and many more.
Being a virtual organization, FOA has very low overhead,
allowing us to offer cost-effective certifications and many free
programs to support our industry.
As of today, FOA has certified this many techs. About 90% come
from our schools but many experienced techs have become FOA
CFOT-certified directly through our "Work-to-Cert"
FOA has almost 200 approved training organizations in about 40
countries around the world around the world.
Certifications Now Last For 3-Years
in 2019, all FOA certifications issued or renewed will be for a
period of 3 years. Most certification bodies worldwide have
standardized on 3 year certifications. FOA has been working with
a number of organizations that use our programs but have
standardized on 3 year certifications. FOA has decided that it
is time to change our policies to align with the majority of
Remember that FOA certification renewals include all the
certifications one individual has for one price. FOA does not
charge for any additional certifications, so, for example, if a
CFOT also has specialist certifications like the CFOS/T or
CFOS/S, they are included at no additional cost when the basic
certification is renewed.
FOA has 14
fiber optic certification programs covering every aspect
of fiber optic network design, installation and operation.
Certifications: CFOT (basic fiber), CPCT (premises cabling),
CFOS/O (outside plant, taught with CFOT included) and CFOS/D
(fiber optic network design).
Skills Certifications (for installers and techs, requires
CFOT): CFOS/S (splicing), CFOS/C (connectors/termination),
CFOS/T (testing), CFOS/FC (fiber characterization).
Applications Certifications (for techs or anyone, including
managers and supervisors): FTTH (fiber to the home), CFOS/L
(optical LANs), CFOS/DC (data centers), CFOS/A (fiber to the
antenna), CFOS/DAS (distributed antenna systems) and CFOS/W
(fiber for wireless)
(what you are reading)
FOA monitors the trade press, websites and other
resources continually to look at what's happening in many
technologies that affect fiber optics. We're tracing
technologies as diverse as wireless, IoT, autonomous vehicles,
smart cities, energy, or anywhere fiber is used to bring news to
FOA continually updates our technical materials, online and
printed, and our curriculum to ensure our readers have access to
the latest technical information and our schools teach the
latest technology and applications. Our printed books are being
updated right now.
FOA created the
FOA Online Guide as a non-commercial trustworthy technical
reference almost a decade ago so the industry would have a
reliable technical reference. In the last year, over 1million
visitors downloaded about 4 million pages of technical
FOA offers free online self-study programs at Fiber
U. In 2017, the number of online sessions doubled to
200,000. Many of those 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.
FOA offers over 100 educational YouTube
videos that have been viewed 2.4 million times.
FOA offers its training programs to other organizations at no
cost to help them train their members properly in fiber optics.
For example, FOA has been working with the Electrical Training
Alliance (IBEW/NECA) for over 20 years, training their
instructors for their apprenticeship programs. We work with many
other organizations and companies to provide the materials they
FOA has about 300 corporate
members - companies in various aspects of the fiber optic
industry worldwide that we list online and offer discounts on
certifications and renewals.
FOA provides speakers for many conferences and even
presentations for use by other organizations to educate people
on the aspects of fiber optic communications.
FOA has a program to provide classroom
materials for STEM
teachers (science, technology, engineering and math)
introducing K-12 students to fiber optics and creating science
FOA provides forums for discussion on various social media. Our
LinkedIn groups have about 5,000 members each. If you are not

In A Career In Fiber Optics?
FOA has created a new YouTube video to introduce students to
careers in fiber optics. It was made for showing to high school
and junior high students interested in tech careers but anyone
interested in a possible career in this field will find it
interesting. If you have kids in school or know teachers, let
them know about this too. Watch the FOA

Optic Education For Students At Any Age
about fiber optics all the time - it's in the news whenever we
hear articles about high tech, the Internet and communications,
and many communities are getting "fiber to the home." But few
people really understand fiber optics or how it works. FOA is
focused on educating the workforce that installs and operates
these fiber optic networks but we're always getting inquiries
from STEM (science, technology, engineering and math) teachers
who want to introduce fiber optics to younger students in K-12

fiber optics. The first FOA video is titled "Fiber
Optics For Teachers." With this video, we show teachers
how fiber works and carries signals and then explains simple
experiments to demonstrate how fiber optics works in the
classroom using some plastic fiber and a laser pointer. Since
many teachers do not know where to get the fiber, the FOA offers
to send them a sample for use in demonstrations in their

we've been contacted by manufacturers, contractors, consultants,
and other types of organizations who ask about becoming members.
We don't certify companies or organizations, we told them, so we
were not sure what we could offer as a benefit of membership.
But then, companies asked about using our educational programs
to train employees, how they could get listed on the FOA website
as service providers or if they could get a quantity discount on
membership or certification for all the FOA members working for
them. That began to sound like a benefit for being an FOA
corporate member. And providing a list of useful suppliers to
the market could be a benefit to the industry as a whole.
So FOA has quietly been letting companies and other
organizations join the FOA to take advantage of those benefits
so we now have several hundred corporate members. We've put then
into a database and listed them on the FOA website in map
form. Here's the map.

Fiber U Self-Study Programs
"Fiber U" free online self-study programs help you learn about
fiber optics, study for FOA certifications or use them to help
create "blended learning" classes. There are two new free online
self-study programs on Fiber
U. Fiber Optic Network Design is for those interested in
learning more about how to design fiber optic networks or
studying for the CFOS/D certification. FTTx is for those wanting
to know more about fiber to the "x" - curb, home, wireless, etc.
- or studying for the CFOS/H certification.
Got to Fiber U
for more information.
Online Self-Study Programs Offer Certificates of Completion
been offering quite a few free online self-study programs on Fiber
U, our online learning site. We are always getting
questions about getting a certificate for completing the course
online, so we have setup an option to take a test online and get
a certificate of completion for these online courses.
While it's not FOA certification, FOA will recognize a Fiber
U Certificate of Completion as background experience to
qualify for applying for FOA certifications. We also intend to
expand the program to more specialized topics as preparation
for FOA specialist certifications.
If you have associates that want to get started in fiber,
have them take this course online to get started. Go to Fiber
U and get started.
Books And Publications
Many textbooks are behind the technology because they are
rarely updated. FOA really keeps our textbooks up to date. We
did a major update a year ago and another was just completed.
The The FOA
Reference Guide To Fiber Optics has been updated
to reflect new components like OM5 fiber, testing for fiber
characterization and more information on installation.
Reference Guide To Outside Plant FIber Optics
has been expanded to include an extensive section on outside
plant construction taken from Joe Botha's
OSP Construction Guide textbook. This additional
material is being added to support the new FOA CFOS/O OSP
tech certification program which now includes of OSP
Basic Fiber Optic Textbook Available in French and Spanish

Design Book Available In Spanish Online
FOA has translated the FOA Guide To Fiber
Optic Network Design book and made it available online to
those studying for the CFOS/D Certification but whose native
language is Spanish. You
can access the Spanish translation of the Design book here.
A printed version will be available in the near future.

Ted's Guides have moved to the FOA website.
Lennie is the place where many if not most fiber techs
begin their education. FOA has just updated the two
guides to ensure they stay relevant - more than 20 years
after they were first written.
Lennie goes all the way back to 1993 when he was created
as the mascot of the original "Fiber U" conference - the
same Fiber U that is now the FOA's web-based training
Lightwave's Guide To Fiber Optics was created
as a beginner's introduction to fiber optics. Over
60,000 printed version of Lennie's Guide were given away
and it became one of the first commercial web pages in
1994. Uncle Ted's
Guide To Communications Cabling was written a
few years later to introduce techs to "Cat 5" - UTP
wiring - that had only recently been standardized in
Lennie and Ted's Guides are used in the current Fiber U
online self-study programs and are still the best place
to start learning about fiber optics.
Ted's Guides are online at the links here, can be
downloaded as printable PDFs and are now also available
as free iBooks on iTunes.
Lightwave's Guide to Fiber Optics and
Ted's Guide To Communications Cabling
are now available free to iPad users who can download them from
the Apple iTunes store. Of course they are still available
online or for download.

LossCalc estimates the optical loss of a fiber optic link. This
will save time for the installer of a fiber optic link needing
to know whether test results are reasonable and/or make a
"pass/fail" determination. It can also help the designer of a
link to determine if communications equipment will operate over
By choosing the type of link (singlemode or multimode) and
specifying the length of the fiber and numbers of connections
and splices, it will calculate the end to end loss of the link.

me or what school offers the certifications I need. The FOA has
about 200 training organizations we have approved worldwide so
finding the right one can be difficult! We've been looking at
ways to make it easier, and we think we've got a good solution.

enjoy feedback, especially when it shows how great some FOA
instructors are. These came from students of Tom Rauch, an
instructor at BDI
"I took your fiber optics certification courses this past March.
I just wanted to let you know that in two weeks I start working
as a fiber optic technician with ___ up in ___. You mentioned on
the first day of the course that there is always one guy in
class who had rubbed his last two nickels together to be there
and, in that instance, I was that guy. Now I'm going to be able
to provide for my family like never before and I owe it to the
certification that I received from you and BDI Datalynk. I just
wanted to thank you again."
"Thanks to our tremendously knowledgeable and patient instructor
Thomas Rauch, who was not only generous in sharing his wealth of
information, but he did so with ease, humor and in a way that
invited curiosity and participation. He was encouraging and
proud of our accomplishments and helped us learn from our
mistakes in a way that did not break our confidence, rather it
pushed us to better results the next go around. The hands on
labs were just AWESOME!" Just thought you should know what a
class act you have representing you in his travels..... but then
again you probably already knew that! : )
In almost 19 years at Verizon and having held numerous
positions, I have gone through many training sessions. I cannot
remember ever having been actually looking forward to coming
back to class quickly after lunch, to get back to the hands on
activities, and walking away with the sense of empowerment that
the information presented was not only relevant but dead on
point accurate! I will be signing up for the Outside Plant class
on March! I can't say enough good things about Tom and his
impact! Feel free to quote me, I can only imagine that he will
open so many doors and change so many lives in the years to
come, with his style of teaching! Great experience, awesome job!"
and FOA Partner on Fiber Optic Training
International Brotherhood of Electrical Workers (IBEW) and the
National Electrical Contractors Association(NECA) through the
National Joint Apprenticeship and Training Committee
a partnership with the FOA has published a new textbook for
training IBEW apprentices and journeymen in fiber optics. The
new textbook uses the material from the FOA Reference Guide To
Fiber Optics with new material and photos from other NJATC
from one of our certified instructors: I want to thank
you and your organization for all the resources you provide for
the students and the opportunity to offer the certification to
the students. The fact that you published the book yourself to
get the cost down and the unlimited free resources on your
website shows a commitment to the public that is second to none.
I let it be known to the students that the FOA is the best in
the industry at supplying knowledge and resources related to the
communication industry. I look forward to passing on the
information that you provide for the industry.

Questions From FOA Newsletter Readers
Testing Cable Before Installation
Does the FOA publish a standard for assessing single-mode
fiber optic cables, prior to use on a specific project?
A: The ANSI/NECA/FOA-301 fiber optic installation
standard covers this in Section 4.1. It recommends visual
inspection and testing if there is any suspicion of damage to
the cable. Many contractors will test a couple of fibers with an
OTDR before installing any cable, just for assurance. It
requires an OTDR with a pigtail launch cable and a mechanical
Cable Bend Radius
We are working on project where we need to know difference
between short term and long term bend radius for fiber optic
A: The bend radius for cables is generally specified
under two conditions - under stress, e. g. when being pulled, it
is a radius 20 times the cable diameter. Relaxed, after
installation, it is a radius 10 times the cable diameter. The
relaxed specification, 10X, is considered a long term
specification. Some of the new high fiber count cables have
different specifications, sometimes 15X or 20X under either
condition. Check with the manufacturer for their specific cable.
Q: If testing a 40KM link with 1KM launch and
receive cords should I be able to see the connector and cassette
splice on each side? My OTDR setup is at 64KM, 300ns pulse and
10 second test at 1310/1550/1625. It shows as a single event so
far but with the pulse width at 300ns won’t that combine the
events into one event during analysis?
A: You will not be able to resolve a connector and splice
close together, especially on a long link like that. 300ns is
almost 60m pulse width! You will see an even of the splice and
Q: We are looking at the specs for two devices, A
and B. The spec sheet of Device A lists it is capable of MM in
850nm wavelength. The spec sheet of Device B lists it can do MM
at 1300nm. If I connect these devices via MM patch cord, what is
the impact due to different wavelengths? Will the transmission
suffer significant loss or since both are multimode, wavelength
A: Fiber works at either wavelength, but transceivers do
not. The attenuation rate for MM fiber is ~3dB/km at 850nm but
only ~1dB/km at 1300nm. But 850nm receivers use silicon
photodiodes while 1300 nm receivers use InGaAs. The 1300
detectors are not sensitive at 850nm and vice versa. So while
the fiber works fine, the electronics do not. They should only
be used with like devices.
questions are now available here on the FOA Guide.
continuing quest to help people understand how to test fiber
optic cable plants and communications systems, we've created two
more "QuickStart Guides to Fiber Optic Testing." They are
simple, step-by-step guides on how to test fiber optic cable
plants, patchcords or single cables using insertion loss or OTDR
techniques and optical power from transceivers. It's as
straightforward as it can get - what equipment do you need, what
are the procedures for testing, options in implementing the
test, measurement errors and documenting the results.
It can't get much simpler.

YOKOGAWA OTDR Has Extended range, High Resolution And Multitasking
One OTDR manufacturer you don't hear as much about is YOKOGAWA
(formerly ANDO) which is too bad - they make some of the best
OTDRs, exemplified by this new model AQ7280. Need long range -
how about 50dB. High resolution - 0.6m dead zone. Like touch
screens, but for some functions want hard buttons, it's got
that. Options for VFL, microscope, light source and power meter,
etc. - it has that too.
But the unique aspect of the YOKOGAWA AQ7280 is it offers
multitasking - you can let do a trace with long averages while
you inspect connectors, make power readings, use the VFL or
info on the YOKOGAWA AQ7280.
thanks Yokogawa for a gift of an OTDR to use for R&D and
