ANSWERS | VERIFIED ANSWERS (100% CORRECT) | LATEST EXAM
UPDATE
What topology do most fiber-to-the-user (FTTx) networks use, which requires
greater fiver 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.
As-built - CORRECT ANSWER - Drawings, route maps, and notes that provide
an accurate representation of a network and its key points in order to simplify
maintenance and restoration tasks.
System margin - CORRECT ANSWER - The amount of attenuation, in dB, that
the system can absorb before the system fails.
Definition of Point-to-multipoint (P2MP) - CORRECT ANSWER - A network
topology that specifies a direct connection from a central or common location to
multiple network locations.
, Optoelectronics - CORRECT ANSWER - any technology that responds to light
waves or is used in a fiber plant, such as a laser, photodiode, optical coupler or
amplifier, etc.
Patch Panel - CORRECT ANSWER - Also known as a connector panel, uses
interconnection sleeves mounted on a panel, which accommodates an individual
optical fiber connection on one side and an equipment connection on the other
side.
Microbend - CORRECT ANSWER - small imperfections in the core/cladding
boundary of a fiver that attenuate the optical signal.
Besides RS-232 ports, what type of interface is common on a 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.
