No Optical Power Is Output on the WDM Side

No optical power is output on the WDM side of the LWM board due to incorrect configuration of the SFP module on the client side. The LWM board reports the R_LOF, R_LOC, TP_LOC alarms.

Fault Type

Optical Transponder Unit

R_LOF

R_LOC

TP_LOC

Symptom

In a network, the LWM board accesses the STM-16 service on the client side but does not output optical power on the WDM side. In addition, the client side of the LWM board reports the R_LOF or R_LOC alarm, and thus the WDM side of the board reports the TP_LOC alarm.

Cause Analysis

The SFP module on the client side of the board is of SCP6801-H1-BNE and supports rates that are only lower than 155.52 Mbit/s. This SFP module does not comply with the specifications of the LWM board. Hence, this problem results from the incorrect configuration of the SFP module type.

Procedure

1. Replace the SFP module of the correct type on the client side to clear the fault.
