Table 24. Custom Test Limit Settings for OTDR Tests
Setting Description
Event Settings:
Connector Loss
Enter maximum and minimum* values as necessary
for the loss of one connector.
Event Settings:
Splice Loss
Enter maximum and minimum* values as necessary
for the loss of one splice.
Event Settings:
Reflectance
Reflectance is the return loss for one event. It is the
ratio of the light reflected at one point on the fiber
to the light that gets to that point from the source.
Reflectance values are in units of negative dB. A
smaller (more negative) reflectance value shows that
less light is reflected back to the source. For example,
a reflectance of -45 dB shows for a good multimode
connection. A reflectance of -20 dB shows for a bad
multimode connection that reflects more light back
to the OTDR.
Enter maximum and minimum* values of reflectance
as necessary for one event.
Splitter Settings:
Splitter
Reflectance
(for Auto PON
OTDR and Manual
PON OTDR tests)
Enter a maximum value of reflectance for a splitter
for each wavelength.
To use the same value for all wavelengths, tap Use
one value for all wavelengths, then enter a value.
N/A The tester will not compare the measurement to this
value and will not give the measurement a PASS or
FAIL result.
* Usually, minimum values are not necessary, but they are available for special
situations. For example, the power at the receiving end of a link may need to be within a
certain range for equipment to operate correctly. The loss budget for such a link may
include minimum values for components.
