What topology do most fiber-to-the-user (FTTx) networks use which
requires greater fiber color code management in its documentation? -
ANSWERS-Point to multipoint (P2MP).
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? -ANSWERS-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, -ANSWERS-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, -
ANSWERS-The meter's calibration must be traceable to the National
Institute of Standards Technology (NIST).
When measuring end-to-end attenuation, -ANSWERS-The light source and
optical power meter must be referenced together prior to making any field
measurement.
A light source -ANSWERS-Is crucial for accurately measuring optical fiber
power and attenuation.
, When a laser light source is used to test fibers, -ANSWERS-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 -ANSWERS-Detect live traffic signals or modulated
test signals on an individual optical fiber.
The most common single-mode wavelengths used by OTDRs are: -
ANSWERS-1,310 nm and 1,550 nm.
Which class of optical transmitter is the safest to the human eye? -
ANSWERS-Class 1.
Improper use of nylon tie wraps can induce this problem: -ANSWERS-
Microbends.
What are potential sources of problems in aerial installations? -ANSWERS-
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? -ANSWERS-Moisture migration into the cable.
In a fiber-optic network, -ANSWERS-The role of maintenance is to
proactively maintain network tolerances and recognize, locate, and remedy
potential problems.
