Fiber
Optic Loss and Power Budgets MiniCourse
Fiber
U MiniCourses are courses on a specific topic that you can
take in about an hour or less. They are based on questions
people ask FOA all the time, so the topics are recommended
by our readers.
Level: Intermediate
Intended For:
Designers
of fiber optic communications networks
Users
of fiber optic communications networks
Contractors and techs who install, operate test and
maintain them.
Objectives:
From this self-study program you should learn:
What
is a link loss budget
What
is a network power budget
How
to calculate both link loss and power budgets
How
to use link loss and power budgets in design and testing
the cable plant
- Prerequisites
When
you finish, you can take an online test on this course to
qualify for a "Fiber U Certificate of Completion." The
test cost for a Fiber U MiniCourse is $10US.
Introduction
Fiber optic link loss budgets and power budgets
are very important for designing and testing fiber optic
networks. During the design phase, the power budget of a
network intended to be used on the cable plant being
designed is necessary to compare to the link loss budget
of the cable plant to ensure the cable plant and the
network are compatible and there is sufficient loss margin
for operation of the network. After the cable plant is
installed, the link loss budget is used as the criteria
for testing the loss of all the fibers in the cable plant,
all of which should be within the loss budget.
This course will introduce the concepts of link loss and
power budgets and show how they are used in designing and
testing fiber optic networks. It is intended for designers
of fiber optics networks and techs who will be testing
these networks.
Note: This course will require you use simple math to
calculate loss budgets, but you may use the FOA
Loss Budget Calculator Online.
Assignments
For
this lesson plan you will be instructed to watch the
video, read
the references
and take a quiz (Test Your Knowledge) to complete the
course.
Lesson
Plans
Watch
the videos, read the section in the FOA Guide and take
the quiz. For this course, we recommend watching the
videos first and then reading the FOA Guide page on
Restoration. There is a short quiz you can use to check
your comprehension. The Certificate of Completion test
is based on those materials.
