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

multimode module is installed. Select a different fiber type or test limit
or install a different module.
