Technical Reference Handbook
Looking at OTDR Test Results
The tester offers three different views of OTDR test results:
a summary, an event table, and an OTDR trace.

PASS: All test results are within limits.
FAIL: One or more test result exceeds the limits. See the OTDR trace or the event table for additional
information.
The value could not be reliably determined. These values are usually preceded by a "<" or ">" (less
than or greater than) symbol. This may occur if the fiber is too long, the signal is weak, or events are
too close together to distinguish losses. In many cases, the OTDR DETAILS screens show causes of the
warning. Press
The length of the fiber in the cabling. If the measured length seems wrong, check the index of
refraction on the Cable tab in Setup. The length does not include launch and receive fibers if launch
fiber compensation is enabled.
Tip: In some cable types, some or all of the fibers may be longer than the cable jacket and some fibers
may be longer than others in the same cable. To adjust the length measurements to represent cable
jacket length, change the index of refraction until the measured length matches the jacket length.
