Fiber Testing and Maintenance ACTUAL
QUESTIONS AND CORRECT ANSWERS
What topology do most fiber-to-the-user (FTTx) networks use, which requires greater fiver
color code management in its documentation? - CORRECT ANSWERS✅✅Point-to-
multipoint (P2MP)
Improper use of nylon tie wraps can induce this problem: - CORRECT
ANSWERS✅✅Microbends
What are potential sources of problems in aerial installations? - CORRECT
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? -
CORRECT ANSWERS✅✅Moisture migration into the cable.
In a fiber-optic network, - CORRECT ANSWERS✅✅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 ANSWERS✅✅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 ANSWERS✅✅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 ANSWERS✅✅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 ANSWERS✅✅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
ANSWERS✅✅Documentation must be updated to reflect the new configuration and
performance data.
As-built - CORRECT ANSWERS✅✅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 ANSWERS✅✅The amount of attenuation, in dB, that the
system can absorb before the system fails.
Definition of Point-to-multipoint (P2MP) - CORRECT ANSWERS✅✅A network topology
that specifies a direct connection from a central or common location to multiple network
locations.
Optoelectronics - CORRECT ANSWERS✅✅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 ANSWERS✅✅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 ANSWERS✅✅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
ANSWERS✅✅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
ANSWERS✅✅1,490 nm, 1,550 nm, and 1,577 nm.
