If the Gauge is Not in the Good Range

Clean the OTDR port and the fiber connector. Use a video
•
probe to inspect the endfaces in the port and fiber connector
for scratches and other damage. If an endface on the tester
shows damage, contact Fluke Networks for service
information.
If the gauge stays outside the Good range, remove the
•
adapter from the module and inspect the adapter for
damage. Make sure that the white plastic ring inside the
center tube shows no damage.
A poor OTDR connection increases the dead zone at the
connector. The dead zone can hide faults that are near the OTDR
connector.
A poor connection also decreases the strength of the signal from
the OTDR. The weaker signal causes more noise on the trace,
which can cause the OTDR to miss events. It also decreases the
dynamic range.
When the test is completed, the quality gauge shows in the
details for the OTDR Port event on the EventMap screens. The
tester includes the gauge with the test results you save.

Port Connection Quality for SmartLoop Tests

For SmartLoop tests, the OTDR Port connection for the second
fiber is the input connector of the loopback cord. See Figures
Figure 91 on page 236 and Figure 93 on page 241. If the tester
shows a message about the connection quality of the OTDR port,
but the OTDR connection on the tester is good, inspect the ends
of the loopback cord.
