the wavelength has achieved the target output power from the transponder. Enter the
following commands on both end points to determine if the launch power has been
achieved.

Ensure that the transponder can provide the required power. If the transponder can

provide enough power, clean fiber connectors from the transponder to the OMD or
CWR8 port to ensure the connections are clean.

OCHKEYDUP
OCHKEYDUP (Duplicate Wave Key)
The NE has detected that another NE in the network is sourcing (heading) an OCh trail
which is using the same wavekeys as one of its own sourced (headed) trails.
The system is designed to prevent this under all normal operating conditions, however,
this situation can happen if the control network was segmented when the OCh trails were
created. If the control network is rejoined and any duplicates are discovered, this alarm
raised. The control network is segmented if the one or more amplifier CN links are down
such that a number of NEs cannot communicate to the remainder of the NEs in the
network.
Having two different OCh trails with the same wavekeys in the same optical network
prevents the ability to distinguish the two OCh trails from each-other with respect to
Wavelength Tracker monitoring capabilities.
