Problem: The TN11MCA board in OSN6800 DWDM occasionally reports the CHAN_LOS alarm when being used on live networks

Findings:

1.       In the OCM module provided by Optoplex, the thread adhesive for the motor of the module solidifies and the motor is unable to move freely. As a result, the performance of some wavelengths fails to be read. In addition, there is a bug in cooperation between the board software and the module.

Solution:

1.       Upgrade the problematic board logic, software & firmware.
