Fiber Testing & Maintenance
Conventional Exam Questions and
Answers 100% Pass
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.
