FIBER TESTING &
MAINTENANCE CONVENTIONAL
EXAM QUESTIONS AND THEIR
COMPLETE SOLUTIONS
Which of the following is true regarding maintenance
of the optical network? choose all that apply.
ITU-T designation encompasses all things voice, data, and
video.
FTTx networks incorporate a point-to-multipoint (P2MP)
optical topology that requires greater fiber color code
management.
What is the purpose of good maintenance practices?
Good maintenance practices minimize failures that might
have otherwise occurred with ongoing neglect and identify
potential performance issues before they become
problems.
What is essential for efficient fiber-optic network
troubleshooting?
Network documentation is essential for efficient fiber-optic
network troubleshooting.
What are some best practices when maintaining the
outside plant? Choose all that apply.
Check aerial spans for obstructions, lashing integrity,
lashing clamps, suspension clamps, physical damage,
snowshoe clamps, radius, cable sag, and dressing.
,Always use riser guards at aerial to underground transition
points.
What are the two most common problems around
patch panels?
The two most common problems around patch panels are
microbends and macrobends.
When might an organization choose to open and
inspect splice closures for moisture and improper
sealing?
For splice closures in underground vaults where the
potential for freezing exists, the cable operator should
open and inspect the closures for standing water; the
operator may choose not to inspect in areas when freezing
is not a problem.
If the network consists of multiple links, the first task
is to identify which link is experiencing trouble. Once
the fault is isolated to a specific link or links, only
three test procedures are required to isolate the fault
within the link. Performing the tests in this order will
quickly locate the most common cause(s) of trouble.
What is the correct order?
test receive, test transmitter, testopticla path between
transmitter and receiver
What are the three elements of an outside plant fiber-
optic network?
The three elements of an outside plant fiber-optic network
are the transmitter, receiver, and the outside plant (the
fiber segments)
Which instrument can be used to find faults within an
optical time domain reflectometer's dead zone?
, A visual laser can be used to find faults within an OTDR's
dead zone.
When changes are made to any network, what is
needed to keep a maintenance plan current?
Whenever changes are made to any network, its
documentation must be updated to keep maintenance
plans current.
What must be replaced periodically in a maintenance
posture?
Date-coded products used for maintenance or restoration
must be replaced periodically in a maintenance posture.
What topology do most fiber-to-the-user (FTTx)
networks use, which requires greater fiver color code
management in its documentation?
Point-to-multipoint (P2MP)
Improper use of nylon tie wraps can induce this
problem:
Microbends
Which of the following statements is true regarding
optimum performance in the fiber-optic network?
The role of maintenance is to proactively maintain network
tolerances and recognize, locate, and remedy potential
problems.
A fiber-optic network maintenance plan should be
developed with which of the following in mind?
The task of compiling the physical document must become
the responsibility of an identifiable position or organization.
What is the best way to prevent problems in outside
fiber-optic splice enclosures?
