Clean the connector and inspect the endface with a video probe. If an
endface is damaged, contact Fluke Networks for service information.
 Remove the fiber adapter from the module and inspect the adapter for
damage. Make sure that the white plastic ring inside the center tube
shows no damage.

 The tester possibly has incorrect settings. Make sure you selected the
correct cable type and test limit. If you did a Manual OTDR test, do an
Auto OTDR test to see if you get the correct results.
 The tester is connected to the link with the wrong type of fiber. Make
sure you use the correct type of launch/tail cords.
See Chapter 15 "Diagnose Problems in Fiber Links" for information on how
incorrect settings and connections can possibly affect your test results.See
the Technical Reference Handbook for information on how incorrect
settings and connections can possibly affect your test results.

shows.
 The test limit requires two wavelengths, but you selected only one. Select
the both wavelengths on the TEST SETUP screen.
 The installed module does not support the selected fiber type or test
limit. For example, the test limit has a singlemode fiber type, but a
multimode module is installed. Select a different fiber type or test limit
or install a different module.
