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.
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.
