Fiber Testing and Maintenance Exam Questions and
Answers 100% Pass
What topology do most fiber-to-the-user (FTTx) networks use, which requires greater
fiber color code management in its documentation? - ANSWER- Point to multipoint
(P2MP)
Improper use of nylon tie wraps can induce this problem. - ANSWER- Microbends
What are potential sources of problems in aerial installations? - ANSWER- Falling
branches, pole attachment problems, and improper sag and loading considerations.
During installation of fiber-optic cable, what does damage to the cable jacket cause? -
ANSWER- Moisture migration into the cable.
In a fiber-optic network, - ANSWER- 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? - ANSWER- The task of compiling the physical document must become the
responsibility of an indentifiable position or organization.
What is the best way to prevent problems in outside fiber-optic splice enclosures? -
ANSWER- The outer jacket and the internal cable structures must be secured
individually to protect the closure and splice trays from the effects of expansion and
contraction.
The troubleshooting process - ANSWER- Should include steps that identify, analyze,
and locate the problem as well as diagnose its source, repair the problem, and test to
ensure the problem is resolved.
, When testing the fiber-optic plant, - ANSWER- An optical power meter is used to
measure the strength of light signals anywhere in a fiber system where a connection
can be made.
As changes are introduced to a fiber-optic network, - ANSWER- Documentation must
be updated to reflect the new configuration and performance data.
Besides RS-232 ports, what type of interface is common on an optical power meter? -
ANSWER- A USB interface can provide easy download of information to a PC
Optical power meters used for testing fiber-to-the-user (FTTx) installations operating
downstream from the headend should be calibrated for which wavelengths? -
ANSWER- 1,490 nm, 1,550 nm, and 1,577nm
A wavelength-isolating power meter is most commonly used in - ANSWER- Point-to-
multipoint FTTx installations
Optical loss test sets perform multiple functions because they include the features of
multiple pieces of test sets. The features of which other test sets are combined into an
optical loss test set? - ANSWER- A stabilized light source, an optical return loss meter,
an enhanced optical power meter, and an optical talk set.
regarding various optical power meter types, - ANSWER- Enhanced power meters
evolved for roles where measurements need to be easily stored, recalled, transmitted,
and downloaded.
When measuring transmit and receive power with an optical power meter, - ANSWER-
The meter's calibration must be traceable to the National Institute of Standards
Technology.
