Diagnosing transceiver modules
The device provides the alarm and digital diagnosis features for transceiver modules. When a transceiver module fails or is not operating correctly, you can perform the following tasks:
Check the alarms that exist on the transceiver module to identify the fault source.
Examine the key parameters monitored by the digital diagnosis feature, including the temperature, voltage, laser bias current, TX power, and RX power.
To diagnose transceiver modules, execute the following commands in any view:
Task | Command | Remarks |
