What topology do most fiber-to-the-user (FTTx) networks use which requires greater fiber color code
management in its documentation? - Correct Answer Point to multipoint (P2MP).
Improper use of nylon tie wraps can induce this problem: - Correct Answer Microbends.
What are potential sources of problems in aerial installations? - Correct 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? - Correct Answer
Moisture migration into the cable.
In a fiber-optic network, - Correct 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? -
Correct Answer 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? - Correct 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 - Correct 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, - Correct 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, - Correct 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? - Correct 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? - Correct Answer 1,490 nm, 1,550 nm, and
1,577 nm.
A wavelength-isolating power meter is most commonly used in - Correct 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? - Correct
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, - Correct 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, - Correct Answer The
meter's calibration must be traceable to the National Institute of Standards Technology (NIST).
When measuring end-to-end attenuation, - Correct Answer The light source and optical power meter
must be referenced together prior to making any field measurement.
A light source - Correct Answer Is crucial for accurately measuring optical fiber power and attenuation.
When a laser light source is used to test fibers, - Correct Answer A 2 kHz modulation provides a test
signal that allows the fiber under test to be detected by an optical fiber identifier.
Optical fiber identifiers - Correct Answer Detect live traffic signals or modulated test signals on an
individual optical fiber.
