14.8.5 MXP_2.5G_10E Card

14.8.5.10 SONET/SDH Overhead Byte Processing

The card passes the incoming SDH/SONET data stream and its overhead bytes for the client signal
transparently. The card can be provisioned to terminate regenerator section overhead. This is used to
eliminate forwarding of unneeded layer overhead. It can help reduce the number of alarms and help
isolate faults in the network.

14.8.5.11 Client Interface Monitoring

The following parameters are monitored on the MXP_2.5G_10E card:
• Laser bias current is measured as a performance monitoring parameter
• LOS is detected and signaled
• Rx and Tx power are monitored
The following parameters are monitored in real time mode (1 second):
• Optical power transmitted (client)
• Optical power received (client)
In case of loss of communication (LOC) at the DWDM receiver or far-end LOS, the client interface
behavior is configurable. AIS can be invoked or the client signal can be squelched.

14.8.5.12 Wavelength Identification

The card shall uses trunk lasers that are wave-locked, which allows the trunk transmitter to operate on
the ITU grid effectively.
is tunable over eight wavelengths at 50 GHz spacing or four at 100 GHz.
