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 111 on page 291 and Figure 113 on page 296. 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.
“STOP” Button for Manual Tests
When a trace shows on the PROGRESS screen for a manual OTDR
test with multiple wavelengths, you can tap the STOP button to
stop the OTDR test at the current wavelength and start the test at
the next wavelength (Figure 98). This lets you control the time the
tester takes to give OTDR results. You can stop the test to get
results more quickly, but the results are possibly less accurate.
