When I press START on my Viavi OTDR to shoot a trace, I immediately get a message saying the connector is bad.
Inspect and clean the connector on the OTDR module as well as the connector on the fiber connected to the testset. This message means the OTDR is seeing a very poor launch condition into the fiber. Try another launch cable if cleaning does not resolve. If a very short launch cable is being used, less than 10 meters, then replace the launch cable with a longer fiber and retest. Verify that the fiber type (APC or PC) matches the port on the OTDR module.
