Chapter 7: Use the OTDR
OTDR Results
171
If the tester made measurements at two wavelengths, tap the
arrow buttons to see results for the other wavelength.
Possibly, some events show only at one wavelength.
: The measurement is within the limit.
: The measurement exceeds the limit.
: The tester does not give a pass or fail result to the event. This
occurs for
OTDR Port
,
Hidden
, and
End
events. This occurs for all
events if you use the
Document Only
test limit because
Document Only
does not have values for limits.
When you use a test limit that has a reflectance limit,
Hidden
events show a
FAIL
status if their reflectance exceeds the limit.
To see details for an event, such as limits for measurements and
the
SEGMENT ATTENUATION
coefficient, tap the event in the
table.
