Enabled: If the media module detects a loss of fiber signal on the
fiber receiver, the media module will immediately send a FEF on
the transmitter of its fiber link to the remote end module. This, in
effect, notifies the fiber link partner that an error condition exists on
the fiber connection.
Note: This switch needs to be set to either generate or detect the
Far-End Fault signal.
Disabled: The media module will not monitor for, or generate Far
End Fault.
