What is the best course of action for the optical time domain
reflectometer (OTDR) operator when the distance measurement
for a strand of fiber doesn't match the sequential distance
markings on the outside of the cable jacket? - ANSWER-Adjust
the index of refraction settings on the OTDR until the measured
distance matches the sequential distance markings.
What is the difference between a reflectance measurementl
and an optica
return loss (ORL) measurement with an optical time domain
reflectometer
(OTDR)? - ANSWER-A reflectance measurement measures
an individual
component and an ORL measurement measures the sum of
all components.
When cleaning the optical port of an optical time domain
reflectometer (OTDR), which connector port requires the use of
a 1.25 mm swab? - ANSWER-Lucent connector (LC).
,Optical time domain reflectometer (OTDR) signatures -
ANSWER-Include
reflective, nonreflective, gain, roll-off, and
ghost types.
When performing an optical fiber acceptance test, - ANSWER-
rganize the fibers
by color, per the TIA-598-A
standard.
Choosing the appropriate optical measurement for post-
installation fiber-optic span tests - ANSWER-Includes splice
loss, attenuation measurements of fiber segments, component
reflectance, optical splitters, accumulated loss, dual
wavelength testing, bi-directional testing, and pass/fail
analysis.
When testing a fiber-optic splitter with an optical time domain
reflectometer
(OTDR), what would cause all the splitter output ports to look
the same on the OTDR's display? - ANSWER-An equal
percentage fiber-optic splitter with all the same drop lengths.
What are possible causes of a reflective optical time domain
reflectometer (OTDR) trace signature? - ANSWER-Connectors,
mechanical splices, optical planar splitters, and fiber ends.
What are possible causes of a nonreflective optical time domain
reflectometer (OTDR) trace signature? - ANSWER-Fusion
, splices, macrobends, microbends, and fused biconical taper
(FBT) splitters.
What type of optical time domain reflectometer (OTDR) trace
results when two
fiber strands with dissimilar cores are fusion spliced
together? - ANSWER-A
gain and loss
signature.
Which optical time domain reflectometer (OTDR)
configuration setting must
always exceed the length of the span under test? -
ANSWER-Range.
What length of fiber should be encased in a dead zone box
according to industry standards? - ANSWER-20 times the
length of the OTDR's shortest pulse width.
How can an optical time domain reflectometer (OTDR) operator
compare an old
fiber trace with a new one? - ANSWER-By overlaying a new
trace on top of a
previously saved
trace.
What does the laser array diagram show? - ANSWER-The
number of optical
