VERSION>
While locating problems on a fiber with an optical time domain
reflectometer (OTDR), .......Answer.........Measurements made
manually for distance measurements identifying reflective events
tend to be easier to make and are more accurate than those
manually taken for nonreflective events.
What should you do to begin diagnosing the cause of a problem
that has been isolated? .......Answer.........Examine the fibers with
the OTDR on both sides of the major event for any inconsistency
in the trace.
,age 2 of 24
What is a key attribute of NOC developed by many cable
operators in large metropolitan areas? .......Answer.........They are
typically staffed 24/7/365 with highly trained technical
analysts to monitor critical network functions in real time.
What is the key benefit to using a DOCSIS-based CMTS?
.......Answer.........Increased network reliability and improved
technician access to critical network data.
What is the optical channel spacing of CWMA systems?
.......Answer.........20nm
What should inspections of fiber-optic aerial and underground
plants include? .......Answer.........Safely making a repair on the
spot of a problem represents a safety hazard or imminent risk to
system operations.
, age 3 of 24
OTDR .......Answer.........Measurements of loss in a dark fiber can
help identify the possible cause and location of a fault on an
active fiber.
DWDM systems .......Answer.........In a fiber network create the
need for an additional piece of test equipment, the optical
spectrum analyzer.
Which of the following is true in regards to the operating
parameters of a fiber node? .......Answer.........If optical power is
within +/- .5dBm of the original acceptance documentation, no
further action is required.
Federal Communications Commission (FCC) proof of performance
.......Answer.........Not C or B
Forward and return sweeps .......Answer.........Are most valuable
for comparing sweep traces over periods of time.
