Fiber
U "Specialist" Skills-Based Courses and Certifications
Outside
Plant (OSP) Construction
FOA
has extensive training programs and certifications on all
aspects of fiber optic cable plant design, installation, testing
and operation, but most of the outside plant (OSP) programs like
the one below begin at the point of preparing the cable for
splicing, termination or testing. This program takes a step back
and looks at the process of construction of the cable plant up
to the point of installing the cable for underground, direct
buried and aerial installations. The Fiber U Outside
Plant Fiber Optics
self-study
program below takes over for the next steps in installation. Complete
the course and you can take the Fiber
U Certificate of Completion
exam.
Outside

Fiber
Optic Network Design
May be used as preparation for the CFOS/D Exam
This 8-part series of self-study lessons is aimed at designers
and managers needing to know how to design, install and
operate a fiber optic network. It's not how to create drawings -
that's another part of design but specific to the software or
method used to create drawings! It's about how to evaluate
customer needs for communications links, choose equipment, design
the cable plant, choose components, create a plan, choose
contractors, pick components, manage the install and finish the
paperwork. The final lesson is 9 case studies of various networks
where you have to make the right choices.
This course assumes you have a basic knowledge of fiber optics at
the CFOT/CPCT level. If not, take the Basic
Fiber Optics or Outside
Plant Fiber Optics course above.

Fiber
U Applications-Based Courses
Fiber
For Wireless
May be used as preparation for the CFOS/W Exam
Wireless communications is growing at an incomprehensible pace.
Cellular wireless is looking at upgrades to 5G technology, small
cells and video streaming. WiFi is reaching gigabit speeds for
enterprise LANs, being deployed in many metro areas and even being
used for line-of-sight links in rural areas. All these
applications depend on fiber optics for backbones. This new Fiber
U self-study program combines the current programs on FTTA (fiber
to the antenna) and DAS (distributed antenna systems) and adds
lessons on Small Cells, the hottest topic in cellular wireless and
WiFi applications. This course is aimed at communications managers
and fiber optic contractors who want an overview of how wireless
technologies depend on fiber optics and how to implement these
systems. Complete the course and case study and you can take the Fiber
U Certificate of Completion exam.
Distributed
Antenna Systems (DAS)
May be
used as preparation for the CFOS/DAS Exam
Cellular data traffic growth has been phenomenal - over 500 times
in the first seven years of smartphones. While most antennas are
outdoors, most call originate from indoors. While everyone expects
cellular connections everywhere, signals have trouble getting
inside large buildings, mass transit tunnesl, etc. and regular
cellular systems are overloaded in facilities where large groups
gather, such as sports facilities or convention centers. The
solution to both problems is to install distributed antenna
systems that provide adequate coverage no matter how big the crowd
or where they are. This Fiber U course covers how a DAS works, its
cabling requirements and how they are installed. Complete the
course and case study and you can take the Fiber
U Certificate of Completion exam.
Fiber
To The Antenna
May be used as preparation for the CFOS/A Exam
Similar to DAS (above), cell towers have been changing to adapt to
the large growth in volume of data traffic over cellular networks.
Towers that one had 3 antennas now have a dozen or more.
Connecting to those antennas from the base of the tower with
traditional coax cables required too much weight and wind
resistance for the tower, not to mention cost, so digital systems
using fiber optic cables have been replacing the coax. This Fiber
U course covers the equipment mounted on cell towers,how cabling
connects them and how those cables are installed and tested.
Complete the course and case study and you can take the Fiber
U Certificate of Completion exam.
Data
Center Cabling
May
be used as preparation for the CFOS/DC Exam
Data
centers are one of the fastest growing areas in information
technology and communications, leading to many large
applications for cabling. There are many different
viewpoints on how data center cabling should be designed and
installed, depending on the point of view. Fiber U takes a
unbiased viewpoint to try to understand how users are
actually building data centers and creates a short
self-study program that can provide a better basis for
understanding this important cabling application. Complete
the course and case study and you can take the Fiber U
Certificate of Completion exam.
FTTx
Fiber To The Home, Premises, Business, Curb, etc.
May
be used as preparation for the CFOS/H Exam
This 6-part series will
introduce you to the varieties of ways that fiber optics is moving
closer or all the way to the subscriber. While some refer to it as
FTTH (fiber to the home), we also have FTTC (curb), FTTP
(premises) and even a new acronym, FTTW (wireless), and this
self-study program will cover all the varieties. While all
varieties of FTTx are covered, most of the course focuses on FTTH
PON networks. Take this course and you will learn about all the
options for FTTx, what network architectures look like, what
standards exist, and get an overview of how they are installed and
tested. A final session will cover design of FTTx and give you a
design exercise to complete. This course is designed for everyone
interested in FTTx. Those new to fiber optics or in management
roles can use this course to familiarize themselves with FTTx
technologies, while those with fiber backgrounds will learn how to
implement FTTx from this course.
Complete the course and
case study and you can take the Fiber U Certificate of
Completion exam.
Optical
LANs (OLANs)
May
be used as preparation for the CFOS/L Exam
Optical LANs or OLANs, are a new
way to build LANs using an all optical fiber cable plant and
electronics derived from fiber to the home (FTTH). Sometimes also
referred to as fiber to the desk or FTTD, POLs, POLANs, passive
optical LANs or FTTO, fiber to the office, these are LANs (local
area networks) that are based on optical fiber cabling, not
copper, and are of great interest to many contractors, installers
and end users. OLANs have been covered extensively in the trade
press and are being promoted by many vendors, so there is plenty
of interest in learning more about them. This course will provide
an overview of the three types of optical LANs, their advantages
over traditional LANs and how to design, install and test them. Complete
the course and case study and you can take the Fiber
U Certificate of Completion exam.

or CPCT certified just by taking online courses at Fiber U because
you can't develop hands-on skills needed for fiber optics on a
computer! But using these self-study courses, you can prepare
yourself for training at one of our hundreds of FOA-Approved
schools around the world, refresh your knowledge from your own
CFOT training or study for FOA exams if you are experienced in
fiber optics and want to apply for direct certification.
If you do
have field experience, you may qualify for the FOA "Work to Cert"
direct certification program.

Fiber U
History
Fiber U
began as a training conference run by Fotec, the fiber optic test
equipment company started by Jim Hayes, now FOA President. Fiber U
combined lectures by many highly knowledgeable instructors and had
participating manufacturers to provide hands-on training on their
equipment. During the 1990s, dozens of Fiber U conferences were
held as a standalone conference and as part of major trade shows
and meetings. Conferences had up to 250 students and 40
vendors, taking over complete hotels and filling conference areas
- even parking lots - with training sessions.
After
the 1994 conference, the Fiber U instructors decided that the
fiber optic industry was ready to have its own professional
society and the FOA was born.
Fiber U also pioneered online training, starting in 1997 using
techniques just like we use today which we learned from a teacher
who was a summer intern at Fotec.
Photos
from the original Fiber U conferences.
Lennie Lightwave was the cartoon mascot created for the original
Fiber U conference in 1993. Lennie has been called the most famous
guy in fiber optics. Lennie Lightwave's Guide to Fiber
Optics was published 20 years ago as a simple, easy to understand
introduction to fiber optics. The web version of Lennie
Lightwave's Guide to Fiber Optics
was one of the first commercial web pages ever and introduced many
people to fiber optic technology. Now Lennie's Guide and Uncle
Ted's Guide to Communications Cabling,
the premises cabling equivalent, are still two of the most popular
sites for getting started in the fiber optics and premises cabling
business.
