Problem Overview

I set my FCOMP OTDR setup selection to Bidirectional but something keeps changing it to NONE automatically.


The FCOMP setup has two parameters that pertain to the OTDR function. The first is the OTDR selection where you can chose the type (Ex: unidirectional or bidirectional) and the second is a Fault Finder setting where the unit only determines the end of fiber. The two are mutually exclusive. If you enabled Fault Finder it will automatically set the ODTR parameter to NONE. To run a full OTDR set Fault Finder to No and then select the type of OTDR to be performed under the OTDR Measurement parameter.
