DIY (Do It Yourself) FTTH Has Become The "Norm"
Eight years ago, when real estate developer Greg Turton contacted FOA
asking if he could built his own FTTH network since no traditional service provider was
interested, FOA already knew enough to help him get started. Not long
afterwards, Kevin Short of the Anza Electrical Co-op asked a similar
question, we were even better prepared. Since then, we've lost count of
the hundreds of people and organizations who have contacted FOA with similar requests.
We even added DIY FTTH to the FOA Guide to help people understand that they can "do it themselves."
Southern Fiberworx, Greg's FTTH ISP, and Connect ANZA were not the first
DIY FTTH networks. The beginnings of DIY FTTH were in cities where the
incumbent service providers were offering unsatisfactory service and
were unwilling to provide upgrades.
The level of Internet service that was expected had moved upwards after
Verizon began FiOS service and the Electricity Power Board of
Chattanooga built the first FTTH network to offer subscribers 1G -
gigabit Internet. Google came along about the same time, promising
gigabit FTTH and over 1,000 cities responded to Google's offer of
building the network for one lucky city.
Municipalities and utilities in the US which were willing to step up and
build their own networks encountered considerable roadblocks -
especially from the incumbents. The lobbyists for the major service
providers got many states to pass laws preventing public organizations
from building broadband networks to challenge the incumbents monopolies
and 19 states still have those laws on the books. Those that took the
option to the voting public for approval often encountered high-priced
opposition campaigns from the incumbents, often based on misinformation,
and most lost the votes needed to proceed with their own networks.
Private organizations like real estate developers, homeowners
associations and rural coops did not encounter those issues. For them it
was more a matter of finding the money and vendors to partner with
them. And avoiding consultants who were either incompetent or
unscrupulous. One group had a consultant take a large payment only to
come back and tell them they could not help them, but kept their money.
Several provided potential system designs that were inappropriate and
unnecessarily costly. We sat through a presentation by one group in a
small town that obviously had something to sell.
But many of the hundreds of contacts FOA has had in the last decade have
gone ahead and built very successful DIY FTTH networks, not only in the
US but all around the world. Many tell us they have used the FTTH Section of the FOA Guide and the free FTTH online training at Fiber U to get started properly, train their people and successfully complete their projects.
We expect to see many more DIY FTTH projects in the future. The events
of the last few years have shown the importance of broadband and the
FTTH networks needed to deliver it. In the US massive government funding
is going to be made available for building networks in unserved and
underserved areas.
Along with the money will come plenty of consultants
to help you get and spend it. It is well known that we lack sufficient
numbers of qualified fiber optic techs to build these networks, but we
also lack qualified consultants who can design networks and oversee
their construction. At least with techs, we have FOA CFOT certification
to qualify them. For consultants, perhaps they should be expected to have the FOA
CFOS/D Design certification. Read on....
Did You Know The FOA Has A Fiber Optic Network Design Certification?
CFOS/D –
Certified Fiber Optic Specialist in Network Design - is the FOA certification appropriate for
designers of fiber optic communications systems. This is a specialist certification covering the
planning, design and management of installation of fiber networks. The KSAs for CFOS/D cover fiber optic network design from concept to completion.
This is a conceptual course, not a course on using CAD or GIS to do the
actual design. It covers the process of designing a fiber optic network
from concept to operation, including what communications are needed, the
routing of the links, the processes of physical design including
choosing components, choosing contractors, supervising the building of
the project, documentation - a project from start to finish.
The CFOS/D certification can be very useful for network
owners, IT personnel, facilities managers, supervisors, network
designers, estimators or technicians involved in the design or
installation of fiber networks. This course is especially recommended
for network owners and planners who may not be familiar with the process
of fiber optic network design as it can make their jobs easier and
their projects better - and help them when working with consultants and contractors.
The FOA Design certification course is often taught along with a CFOS/H FTTH course when network owners are building their first FTTH networks.
A CFOT or equivalent basic knowledge of fiber optics and communications
networks is helpful for taking this course but not required. A review of
the basics of fiber optics is included in the course for those with no
background in fiber
optics.
The online design course is on Fiber U and like all the online courses, free.
Example Of Rural Broadband Confirms FOA Article
Back in the March FOA Newsletter,
we ran an article "More Thoughts On Broadband For Rural Areas" where we
showed a map on the state of Missouri showing how many unserved and
underserved areas are in a typical state. This month,
Telecompetitor ran a news item "Gateway Fiber Awarded $10 Million Grant to Expand Missouri Broadband."
Wright City, MO — Wright City-based Gateway Fiber has been awarded $10 million
as part of a $42 million grant to the State of Missouri from the
National Telecommunications Information Administration (NTIA) to expand
broadband internet coverage in underserved communities. Gateway received
the largest share of this funding state-wide.
The US Department of Commerce (DOC) announced in late February that
Missouri will receive the grant money to expand broadband coverage in
several communities where residents do not currently have access to
high-speed internet.
Locally, the grant funds will allow Gateway Fiber to reach nearly 5,000 homes and businesses in underserved communities in Lincoln and St. Charles County, including areas surrounding St. Paul, Josephville, Winfield, Moscow Mills, and Old Monroe.
Through Gateway’s future-proof fiber optic network, these areas will be
able to access the internet with hyper-fast symmetrical speeds up to 1
Gig, the same fast speeds available in major metropolitan areas.
Here is a map of those 5 communities:
While these communities were in the unserved or
underserved areas, they are only ~50 miles (~80km) from the major city
of St. Louis.
Here are their populations (2010):
St. Paul 1,829
Josephville 376
Winfield 1,404
Moscow Mills 2,509
Old Monroe 265
These are exactly the kinds of towns we are referring
to as "rural;" small towns are where the bulk of the rural population
lives, not on farms.
The Cost
And the numbers are right in line with what we expect: $10 million for
connecting 5,000 homes and businesses is $2,000 per subscriber, what we
expect for rural broadband networks and, almost the same cost that was
quoted for AT&T to connect up homes in Oldham County, KY Kentucky as
reported in theNews section of the May FOA Newsletter.
Interesting Reading:
The NTIA Notice of Funding Opportunity (NOFO) - ONLY FTTH Projects Need Apply
You are going to see the term "NTIA NOFO" a lot now. It will refer to
the document describing the NTIA $43billion fund for broadband. If you
are at all interested in the program, we suggest you download a copy and
read it yourself. We did and found it extremely interesting.
The first thing we did was to search the PDF file for "fiber" to see if
fiber optics was called out specifically. We found 10 locations where
fiber was mentioned and we found these most interesting reading:
Page 7:
With respect to the deployment of last-mile broadband infrastructure,
the Program prioritizes projects designed to provide fiber connectivity
directly to the end user.
Page 14:
The term “Priority Broadband Project” means a project that will
provision service via end-to-end fiber-optic facilities to each end-user
premises.(Footnote 9)
Footnote 9: A project that will rely entirely on fiber-optic technology
to each end-user premises will ensure that the network built by the
project can easily scale speeds over time to meet the evolving
connectivity needs of households and businesses and support the
deployment of 5G, successor wireless technologies, and other advanced
services.
Page 42:
NTIA has determined that “Priority Broadband Projects” are those that
use end-to-end fiber-optic architecture. Only end-to-end fiber will
“ensure that the network built by the project can easily scale speeds
over time to ... meet the evolving connectivity needs of households and
businesses” and “support the deployment of 5G, successor wireless
technologies, and other advanced services.
There will be fiber: that's very important to those seeking grants and to organizations like
the FOA who will be involved in OJT and workforce development for these
projects.
Page 66: (Dig Once is called out also)
Any Funded Network deployment project that involves laying
fiber-optic cables or conduit underground or along a roadway must
include interspersed conduit access points at regular and short
intervals for interconnection by unaffiliated entities. Where a project
proposes to lay conduit, Eligible Entities shall require prospective
subgrantees to propose to deploy a reasonable amount of excess conduit
capacity and to propose a conduit access point interval as part of the
grant application process and shall consider the adequacy of the
prospective subgrantee’s proposed excess conduit capacity and access
points when evaluating the application.
Download your copy here: NTIA Notice of Funding Opportunity
Another NTIA page that is very useful is the NTIA "Broadband USA" page. It has a comprehensive listing of all the state broadband offices and a very good FAQs page.
Should You Trust A Website Called "broadband.money" ?
Almost immediately after the IIJA broadband program was announced, a website called "broadband.money"
popped up. Yes there is a higher level domain like "com," "net" and
"org" called "money" and you can guess what this is all about - money.
The home page with the photo of $100 bills just screams "GREED!!!"
Broadband.money describes itself on its home page as "The fastest way to
discover and win broadband grants." Then they invite you to "Enroll
today to find and win funding in your territory." To participate in this
- whatever it is - requires a very trusting - or perhaps gullible -
person. There is no indication of what or who is behind the website or
what they are peddling. The domain of the website,
"broadband.money" is registered privately, so there is no information on
the backers.
There is an email contact given, so we contacted them for more
information and they responded. It turns out to be the creation of a
Silicon valley software company called Ready.net
which sells software to ISPs but has a division that is a venture
capital organization. It is unclear what expertise they bring to the
process they are offering, although one of the people involved is
familiar with Tribal affairs.
In our contacts with them, we have encouraged then to be more open about their
motives. In the meantime, you can use the website to find the contacts
for each state's broadband office: https://broadband.money/state-broadband-offices (but the NTIA "Broadband USA" page
looks more comprehensive.
If you are looking for trustworthy information, we suggest you contact the Pew Charitable Trusts group.
Another startup organization, American Association For Public Broadband,
is comprised of actual municipal broadband organizations aiming to
build their own DIY broadband systems. According to an article in Community Networks,
"AAPB will have a more focused role by helping to facilitate better
communication between local, state, and federal officials as,
historically, lawmakers have almost exclusively been advised by the
lobbyists and trade associations who represent the monopoly interests of
Big Telecom." “Our
board is comprised of municipal officials. There are no vendors on our
board or incumbents. This is an organization for public officials
responsible for broadband projects.”
Help In Remembering Color Codes (More Free Stuff From FOA)
Recently FOA was asked if we knew of a pocket guide
to fiber optic color codes. We did not but recommended the page on color
codes in the FOA Online Guide, easily read on your smart phone of
tablet. But the idea of a pocket guide seemed to make good sense, so we
made one ourselves, as you can see here.
The FOA Guide To Fiber Optic Color Codes covers the basic color codes
for fibers and buffer tubes plus connectors and cables. On the back, we
added QR codes to link you to the FOA Online Guide for technical
information and Fiber U for free online learning.
FOA is sending these free to every new CFOT and every CFOT renewal in the US and Canada.
So when you get your FOA ID card, you get a FOA Color Code pocket
guide. Sorry we can't mail these outside the US, but we will share the
design with our schools around the world so they can make them locally
for their students too.
Print Your Own:
Go to the Color Codes page in the FOA Guide.
Follow the links to download the PDF files for either a pocket size
version you can print on a color printer, cut out and fit in a pocket or
a full page version you can save to your smartphone, tablet or
computer.
Underground Construction Can Be Extremely Disruptive
Sometimes we write about how several methods of underground
construction like microtrenching and directional boring can be done with
minimal disruption. But when things go wrong, they can be very
disruptive - and dangerous. We've run photos of directional boring
being done in downtown Santa Monica before, noting how it can be done
with precision, the driller following a tech with underground locating
equipment to ensure avoiding buried utilities.
But sometimes things go wrong. On May 3rd, a fiber optic construction
crew boring in he same area as the work we reported on in the FOA Newsletter in October 2019
hit a 2 inch (50mm) gas line causing a leak that took more than two
hours to shut off. The Santa Monica Fiber Department required all
businesses in the area - the primary shopping area in downtown Santa
Monica - to close for the afternoon. Santa Monica Daily Press.
Directional boring punctured 2" gas line in downtown Santa Monica (Photo by Emily Sawicki, Santa Monica Daily Press)
This is not the only time Santa Monica has been shut down by fiber optic
construction crews hitting gas lines. A year ago in the May 2021 FOA Newsletter
we reported that a fiber contractor made an even bigger mistake - they
hit a 16 inch (400mm) high pressure gas main. Quick action by the Santa
Monica Fire Department closed the area off and shut down electrical
service to prevent a major fire or explosion. FOA was unable to get any
details on how such a serious hit could occur.
The fact that two such events could happen in a major city like Santa
Monica shows how big a problem urban construction can be. Prevention
requires vigilance, careful understanding of documented underground
utilities and continuous active location during the boring process.
Who Can Use Fiber U? Everybody Can Use Fiber U!
Last month in the FOA Newsletter we had an article discussing the free Fiber U
online courses and how they can be used to help learn more about fiber
optics. We want to emphasize one point - FOA is free to anyone and
everyone. You don't need to be Certified by the FOA or be an FOA
Approved school to use Fiber U.
When the FOA was founded in 1995, our charter was "to promote
professionalism in fiber optics through education, certification and
standards." The founders wanted to provide educational resources for the
industry that would benefit everyone. Many of the founders were
manufacturers who recognized the need for an umbrella certification that
would help them in offering their own installer certifications for
their warranty programs. It would help educate their customers to
simplify the process of working with them to design, procure components
and install their networks.
Fiber U is a major part of the FOA's commitment to the fiber optic
industry. It's one of the services we provide free to the industry and
is often credited as a major contributor to the growth of the workforce
that is essential to our industry.
FOA also makes available a "Certificate of Completion" for those wanting
or needing evidence they have completed the course successfully. The
Certificate of Completion test uses our online testing service and has a
nominal cost for the test.
FOA welcomes everyone to use the free courses at Fiber U.
- We strongly encourage fiber installers who are
learning by OJT to use Fiber U to help their technical knowledge and
abilities to grow.
- All schools are welcome to use Fiber U, even if
you do not offer certification with your courses; right down to the
high school level.
- Employers, you can use Fiber U to build your
workforce and make them more productive. In today's world, hiring
experienced fiber techs is hard - they are all busy right now - but
hiring novices and training them by OJT using FOA's "OJT to Cert"
program can help solve your personnel problems.
Everybody's welcome to use Fiber U.
The FOA Guide To Fiber Optic Projects includes this timeline and comments on project planning and implementation.
FOA Broadband Planning Page. The FOA has a page devoted to
understanding the IIJA and how to obtain help in planning and funding
broadband projects.

The California Department of Technology (CDT) released its draft map and
design recommendations for the proposed statewide broadband middle mile
network. The map outlines nearly 9,000 miles of infrastructure intended
to serve as a backbone for last-mile connection projects to underserved
and unserved communities throughout the state.
The link will take you to a very complete description of the network
which should be of interest to contractors in CA (obviously) but others
may learn a lot about how complex networks are designed.

Fiber Optic Sensor Monitors Volcanic Activity At Mt. Etna In Sicliy
Dr. Philippe Jousset, a scientist and researcher with
the GFZ German Research Centre for Geosciences (Potsdam, Germany), and
Gilda Currenti, a researcher at Italy’s National Institute of Geophysics
and Volcanology developed a method for monitoring seismic activity
around volcanoes using fiber-optic cables as sensors analyzing the light
backscattered in the cables when deformed by vibrations. The
technique—distributed acoustic sensing (DAS) with optical fibers—allows
for more accurate identification of volcanic events remotely and image
hidden near-surface volcanic structural features.
Putting their research into
practice, the team is monitoring one of the world’s most active
volcanos, Mount Etna in Sicily, Italy. They have been able to detect and
characterize strain signals associated with explosions in Mount Etna
and locate their origin with a 2D template matching picked and
theoretical wave arrival times. Wavefield separation has enabled
researchers to “incrementally investigate the ground response to various
excitation mechanisms,” and “identify very small volcanic events”
related to fluid migration and degassing.

Wired Magazine also had a good overview of using fiber optic cables as sensors.

Useful Gadget For Installing Patchcords Indoors
Sometimes completing a FTTH home install or even a commercial project
requires running patchcords through walls or conduit. The problem is how
to do this without damaging the connector. Here is a gadget that was
designed to protect the connector on a patchcord in that kind of
install.
It's a plastic cover for a SC connector that provides
protection and connection to pulling rods or ropes/tapes. It's very
small so a small hole is all that's necessary to pull the cable. For
FTTH PON installs where only one fiber is needed, this seems to be a
really useful tool.

FTTH Update In South Africa
Joe Botha of Triple Play Fiber Optics in South Africa
sent us a note to update us on what their FTTH network providers are
at-present doing in SA, using Nokia OLT’s and ONT’s.
Equipment has a 38 dB power budget: Tx +6 dBm & Rx -32dBm.
They do a cascaded split consisting of:
x2 at the OLT.
x4 at the distribution cabinet.
x16 at distribution points close to the homes = 128.
The obtainable distance: for a x64 fiber split = 27km and a x128 fiber split = 10km.
That's impressive and certainly expands the reach of a FTTH PON.
Joe and his instructors are teaching courses in SA regularly now using
basic guidelines for pandemic safety. Here's a recent course classroom:

The Polarity Of Loss
Readers know we've been investigating the strange
reversal of polarity for optical loss measured in dB for some time. Here
is an interesting pair of definitions from a new international standard
adopted in the US.
The thing to note is attenuation or loss is referenced by
P(in)/P(out) - e.g. reference to the output signal, not the incoming
signal - in the basic equation The alternate equation used
P(out)/P(in) which which follows scientific and technical convention but
adds a negative sign to get the result to be a positive number.
But reflectance and return loss are referenced in relation to the
incoming signal, with does follow scientific and technical convention.
No consistency indicates a lack of knowledge of scientific and technical convention - just a desire to get rid of that pesky negative sign in the meter display.
Warning For Techs Doing OSP Restoration
FOA recently received an inquiry that was a new one; whether techs
working on restoring OSP links should be concerned about eye safety if
the link used fiber amplifiers. To answer this question, we had to do some research on fiber amplifiers.
The short answer is YES, you should be concerned. The long answer is
more technical and includes details that every OSP tech needs to know.

Questions/Comments From FOA Newsletter Readers
June 2022
Differences in OTDR Traces
Q: What causes the differences in otdr traces for fibre cores that are in the same cable?
A: Several things can cause the fibers in a cable to have differences in their OTDR traces:
Differences in fiber from different production batches including fiber that may come from different preforms.
Differences in stress on the fiber caused by inconsistent cable design and manufacture
Of course differences in splices including stress on fibers in a splice
closure and terminations including stress on fibers in racks and panels.
"Mining" Cables In Data Centers
Q: Is there any documentation out there on best practices for DC cable mining? Any help would be greatly appreciated.
A: This has been a topic in premises cabling since first
proposed by NFPA for the NEC twenty years ago. FOA has gotten this
kind of question before for many different circumstances, but I must
admit that I know of no recommended procedures or standards for the
removal of abandoned cable.
Cable “mining” often refers to the removal of
underfloor cable, may apply to cables in trays and is hard to get
information online - search for “Cable mining” and you get links to
sellers of cables designed to be installed in mines (coal, salt,
minerals, etc.) underground!
The biggest problem with removing unused cables is
identifying the cables to remove. Underlloor cables are particularly
bad, it seems, since you have generations of abandoned cables, often
poorly marked, sometimes mixed with power cables. With metallic cables,
you can sometimes use an ancient telephone tool, a “toner” to trace
cables, With fiber you just have to be careful that you identify the
cable before you cut.
It’s always better to remove small sections, especially if you can tug
on the cable and verify it each time before cutting. We’ve seen photos
of an early data center with cable trays 2 feet deep by 4 feet wide full
of about 4,000 fiber optic cables. After seeing that you understand why
the new high fiber count cables (1728, 34456 and 6912 fibers) are
desirable!
Calibration of Fiber Optic Power Meters
Q: Why does this tester sold so cheap show the same value for 1310 and 1550?
A: We’ve purchased and tested several
of these inexpensive meters based on questions from our instructors and
readers. They have a similar “feature” - they are not calibrated to
international standards of optical power, so when you measure dBm, the
result at any wavelength may vary considerably from a meter by a major
manufacturer who does calibrate properly.
However, these meters have a menu item that allows you to calibrate them
yourself. We've calibrated all the ones we tested to match our
calibrated instruments and after that they work OK.
Interestingly, they show loss as negative dB, which is how we think it
should be. Some large, famous manufacturers manipulated the standards to
make loss a positive number, so if you measure gain, it is considered a
fault.
May 2022
Designations For Fibers
Q: I'm currently working on a project involving optical fiber
with VMS signs, CCTV cameras and other ITS equipment. I was wondering if
there is a standard or a good practice which describe the typical
assignation for each optical fiber on a 6 fibers cable for
example? By that, I mean :
- fibers number 1 and 2 : VMS;
- fibers number 3 and 4 : CCTV;
- fibers number 5 and 6 : spares
A: There are several ways people assign polarity on duplex links.
The way you suggest is the most common I believe. Use the odd number
fibers to transmit in one direction, even number fibers to transmit in
the other direction and document the color codes.
Storing Fiber Optic Cable On Reels
Q: is there a "standard" for how to store a fiber optic cable reel?
A: This is another detail that has not in my knowledge ever been
included in a standard. However manufacturers usually put a note on the
reel to keep it upright - standing on the edges of the spool sides, not
flat on one side of the spool. If the fiber is to be stored for a
period of time, it should be stored in a cool dry place and the ends
sealed with electrical tape.
(Photo storing cable on reel)
Optical Power Of FTTH Signals
Q: I wanted to know on a fiber to home what is the optimal signal
strength I should receve at? I have a leg that is 21 km long I
receive at 1490 at -22 dBm is that to low, everything looks good on my
traces
A: The specifications for GPON are here. https://foa.org/tech/ref/appln/FTTH-PON.html
The standard for GPON calls for receiver power at -13dBm max to -28dBm minimum, so -22 dBm is OK.
April 2022
850 LED Test Source
Q: I need to test multimode fiber at 850 nm but sources are hard to find and expensive. Can I use a laser?
A: Multimode
fibers should be tested with an LED. Lasers have several problems in
multimode fiber that may cause untrustworthy readings. The problem is
that LEDs are no longer used for transmission systems; every MM system
now uses VCSEL transmitters, a surface emitting laser. As a result most
LEDs at 850nm for MM have gone out of production. Two engineers I know
who have been looking for them say there is now only a few sources and
the price is much higher that of a few years ago. We've been buying used
test sources on eBay for training.
105 Micron Fiber?
Q: I have a customer asking about 105um fiber. Does it exist? What is it basically used for? After FOA suggested a clarifying question to the customer: The
fiber is for Power over Fiber(PoF). The construction is 105um fiber
with 125um cladding. The question or assumption would be – The
termination would be the same as 50,62.5 or 8.3um with a 125um cladding?
A: The people who do laser surgery and power over fiber
use special step index fibers and SMA connectors. The power density can
be very high so the heat can build up in the cable. SMA connectors or
the metal ferrule swaged-on connectors are often used for their
all-metal construction with the ability to withstand heat and sometimes
the need to be drilled for special fiber diameters. Because of the high
power, the polish needs to be low reflectance, so we’d recommend using a
wet polish and end with a very fine polishing film - 0.3 microns or so.
Like polishing SM for DWDM.
Cleanliness is very important for these applications. I remember a call
from a doctor doing laser surgery who kept ruining cables because they
were dirty and the high power literally exploded the dirt and pitted the
ends. When that happens, sometimes they can be polished out but often
they are ruined. The same thing happened to the 120 inch telescope at
Lick Observatory when Joe Wampler tried using it to laser range to the
retroreflector Apollo 11 left on the moon. Exploding dust pitted the
aluminization on the mirror.
Gel Leaking From cables
Q: We have several instances where gel from inside
the fiber optic cable has leaked into the splice closure. I have seen
some information about sealing the ends of cables so that this doesn’t
happen but cannot find a specific method or procedure for this or what
to use for a sealant. Is this something that is common practice for
outside plant cables? The gel creates a mess and definitely makes
reentry for additional splicing more difficult. If there is a way to
prevent or minimize this I would like our technicians to start
implementing it.
A: When you install the cable, after inserting the cable
in the splice closure and/or the budder tubes in the splice trays, seal
the end with silicone RTV adhesive. It needs some time to cure but that
should prevent the gel leakage. Or next time, order dry water blocked
cable which will not have this problem.
Single Fiber DWDM
Q: Can you do bidirectional links on a single fiber with DWDM? (Dense Wavelength Division Multiplexing)?
A: A company Called Edge Optical Solutions sells
multiplexers for bi-directional DWDM on one fiber by using
adjacent wavelength channels for each direction. It is good to ~400km
with coherent transceivers but cannot use fiber amplifiers for
repeaters.
March 2022
Maximum Fusion Splice Loss
Q: We have set 0.4 dB as our max for all losses per splice
and my counterparts argue that customer quality will not suffer with a
1.0db-1.5db loss at a splice. What do you think?
A: We would argue that the issue with high loss splices is more
one of reliability. Most fusion splices of singlemode fiber are 0.05 to
0.1 dB A splice that has more than ~0.2dB loss probably has some
inclusion (dirt that got on the fiber after cleaving) or an air bubble
with means the splice is deficient in strength and may fail over time.
If the network is operating at high power with WDM and fiber amplifiers,
the inclusions or bubbles may produce heat which can cause failures. At
very high speeds or using coherent communications over long lengths, it
might affect dispersion.
Another Way Of Expressing dB?
Q: Just wondering what to
think about presenting dBm as a percentage of power, using either a
linear measurement or quadratic equation ?
I recently came across this article : [https://lnkd.in/eYkfpHzD] I
realise it's Wi-Fi signals here, but can you compare this to anything
concerning optical loss or gain , given we're still using dB and dBm ?
A: I had to read this 3 or 4 times to get the idea. Basically
he suggests converting dB, a nonlinear log scale, to a linear scale
expressed in %. Following his steps (assuming I understand his system) ,
100% = 0 dBm (1mw), 90% = -10dBm = 1/10mw = 10% of the original
signal, 80% = -20 dBm = 1/100 mW = 1% of the original signal.. So 80% =
1% of the original signal. And that’s where it seems a bit nonsensical.
70% would be 0.1% of the original signal,,,
We fail to see what this “new math” accomplishes.
OTDR AutoTest
Q: Would we say that OTDR 'Smart' test capabilities are commonplace on newer models or only on some manufacturers meters ?
Maybe it's additional software that can be thought of as an upgrade ?
A: Some form of “auto test” has been available on most OTDRs
for 20 years or more. Early versions were not very good; they usually
just made a test under some average test conditions and reported the
results. Modern OTDRs use more powerful computing power to make several
tests and determine which conditions are best for the fiber being
tested. By optimizing the range, pulse width, number of averages, etc.
it can usually produce fairly good results. We don’t think the cost of
the OTDR is an issue for new ones because users expect all of them to
have a good auto test function. As to whether an older unit could be
upgraded, that would depend on the manufacturer and if they still
support that product. An OTDR less than 5 years old should probably be
able to be upgraded.
February 2022
MM Splice-on Connector On Singlemode Cable
Q: I encountered a situation where a MM
mechanical connector was used on a SM fiber and passed on an OTDR test.
The client and I are interested in understanding how these connectors
could have passed?
A: The joint between a multimode and
singlemode fiber should have vrey high loss, ~17-20 dB, depending on the
mode fill of the MM fiber. However the short length of the MM fiber,
~10mm, might not be enough to cause the modes to fill in the short fiber
in the connector, resulting in relatively low loss.
Eric Pearson, one of the most knowledgeable people on connectors
expressed this idea then tested it with 100m singlemode connected to a
second singlemode cable. The second singlemode cable has an OM3 LC
unicam connector, An EXFO ftb-400 OTDR indicates a 2.09 dB drop. That is
way too much to pass a test but nowhere near the loss that could be
expected from the MM/SM joint. See the OTDR trace above.
November/December 2021
Fiber Optic Color Codes Reference Chart
Q: Has anyone made a fiber optic pocket reference chart that has cable
color orders, frequencies, or other commonly used info on it?
A: The FOA has a page on its Online Guide that covers color codes
(https://foa.org/tech/ColCodes.htm). It is the most popular page in the
FOA Guide! It works great with a smartphone.
Underground Utilities Location
Q: From an OSP engineer: Is there a resource for
underground utilities that we could use on our engineering designs? I
know some counties offer this info but is there a single resource for
all?
A: If you are in the US, the Common Ground Alliance (https://commongroundalliance.com , https://commongroundalliance.com/Tools-Resources/Resources-Library/Toolkits)
is a resource for designers and contractors looking for information on
underground utilities. Their “CGA Best Practices”
(https://bestpractices.commongroundalliance.com) is the best reference
for damage prevention.
Otherwise, the local authorities and utilities are the best source. The
department that issues permits is usually the place to start.
Even with that information, it is recommended that the contractor do
their own search using underground locating equipment before digging.
You may find this page in the FOA Guide on underground cable construction useful. ( https://www.foa.org/tech/ref/OSP_Construction/Underground_Construction.html )
Reflectance
Q: What is the importance of reflectance and all the other numbers in installing and trouble shooting a fiber circuit?
A: Reflectance has always been a secondary issue to connection
loss but has some important issues that need consideration. There are
two basic issues with reflectance, affecting with the output of laser
transmitters and creating background “noise” in a fiber link.
Reflectance can interact with the laser chip itself, causing laser
transmitters nonlinearities or random fluctuations in the output. The
background noise is a secondary issue, but can be seen in ghosts in an
OTDR trace. The light bouncing back and forth in the fiber that causes
ghosts will be added to the signal at the receiver end, adding noise to
the actual signal. Both these effects are more significant on shorter
links, for example FTTH or LANs using PONs (passive optical networks).
We always recommend using APC (angled physical contact) connectors on
short SM links. And most short SM networks do use APC connectors.
FOA tries to stick to the definition that reflectance is the light
reflected from a connection but some others call it “return loss.”
Return loss has been defined generally as the combination of reflectance
and backscatter from the fiber, and that’s how OTDRs measure return
loss. Standards vary in the definition sometimes.
Here is a FOA Guide page on reflectance that gives the basics and
explains how it is tested.

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.

FOA Network Of
Approved Schools Continues To Grow
The
need for more fiber optic networks to support
broadband and wireless/5G networks has led to a
strong demand for more trained and FOA-certified
techs, and that has led to a demand for more
training organizations. FOA has been adding new
schools and certifying new instructors to meet the
demand. Here are two new schools this month and more
added recently.
New this month:
Western Wyoming Community College, FOA Approved School #401

Need A Fiber Optic Course Onsite? Invite an FOA School To Come To You
FOA often gets inquiries from an organization that
has personnel that needs training in fiber optics. Recent inquiries have
included contractors, a manufacturer of high-reliability products using
fiber optics and a cable manufacturer. In many cases, where there are
several people needing training, FOA can recommend a FOA Approved School
and Certified Instructor who will come to their location to teach a
class. The advantage is of course the savings in travel costs if
the class comes to you, but it also offers the opportunity to customize
the course to fit your needs, even use your equipment or work on your
components, so the training is more relevant to those taking the class.
Contact FOA to discuss the idea of a custom, on-site class to see if it will better meet your needs.
FOA/Fiber U
On-The-Job Training (OJT) Program
The
FOA Fiber U OJT program combines online study at
Fiber U with OJT with mentoring by experienced
co-workers and their supervisor to help new employees
develop into FOA-certified technicians in only
one year. Upon completion
of this program, the trainee will be prepared to
take the exam for the FOA CFOT (Certified Fiber
Optic Technician) and/or CPCT (Certified Premises
Cabling Technician), the most widely recognized
fiber optic and premises cabling certifications in
the industry.
The FOA Fiber U “OJT-To-Cert”
program includes both fiber optics
and premises cabling (copper, fiber & wireless),
so it covers techs working in both outside plant and
premises jobs.
Like other FOA
programs, the OJT-To-Cert program is free. If you
and/or your company is interested in the FOA
OJT-To-Cert program,
contact FOA.
To explain how OJT
works and FOA's OJT-To-Cert program, FOA created a
short 10 minute YouTube video that explains what
OJT is, who uses it and how to use Fiber U to
organize and enhance OJT for new employees and
experienced workers too. Lecture 62: On

"Work-To-Cert" Program
Experience Plus
Online Study At Fiber U = FOA Certification
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

New Fiber U Course: Fiber Characterization
FOA has added a new course at Fiber U on Fiber Characterization. Fiber
characterization is the process for testing long fiber cable plants for
its ability for carrying high speed communications. With so many
networks now operating at 100, 200, 400 or even 800 Gb/s, fiber
characterization is important, especially on older fiber optic cable
plants.The free Fiber U Fiber Characterization course is available in two forms, as a standalone Fiber U fiber Characterization Course with its own Fiber U Certificate of Completion and as a separate Lesson in the Fiber U Fiber Optic Testing course. This course is recommended for those studying for the FOA CFOS/FC Fiber Characterization certification.
Fiber U MiniCourses: Got An Hour Or Less?
Learn Something New About Fiber Optics.
FOA
has introduced a new type of Fiber U
course, the MiniCourse, a free online course you
could take in a short time, perhaps as you ate lunch
at your desk or took a coffee break. The
topics of these courses should explain what they are
about, and these are all very important topics to
fiber optic techs.
Fiber Optics In Communications
How Optical Fiber Works
Fiber Optic Network
Restoration
Fiber
Optic Connector Identification
Fiber U Color Codes
The Mysterious
dB of Fiber Optics
Fiber Optic Cable Bend Radius
Fiber Optic Link Loss And Power
Budgets
Fiber Optic Connector
Inspection And Cleaning
Fiber Optic Media Conversion
Fiber Optic Cable Midspan Access
Reading An OTDR Trace
Reference Cables For Testing
Fiber Optic Attenuators
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.
All these free courses and many more
are available at Fiber U.
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 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
Some
schools have been closed during the pandemic, so FOA
has been working with 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.
Offline Fiber U
FOA has also created offline Fiber U modules
to allow students with poor or limited
Internet access to use the Fiber U Basic Fiber
Optics and Premises Cabling programs without
Internet access. Contact FOA for information
on using this option.
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 with our FOA's
OJT-to-Cert Program,
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? Click
on the link below or contact FOA for
more information.
FOA's OJT-to-Cert
Program
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.
FOA School Offers
Toolkit With Online Training
Slayton Solutions
(FOA Approved School #156) is offering a simple
fiber optic tool kit that includes a 29-piece set
of fiber optic tools and a power meter along with
training videos and online instruction for only
$499. 29 Piece Kit includes all tools and devices
a technician needs to install fiber optic
connectors and test optical power. Information on the kit is

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
