Vendor Name Name of vendor who customizes the transceiver module.
Diagnosing transceiver modules
The device provides the alarm function and digital diagnosis function for transceiver modules. When a
transceiver module fails or inappropriately work, you can check for alarms present on the transceiver
module to identify the fault source or examine the key parameters monitored by the digital diagnosis
function, including the temperature, voltage, laser bias current, TX power, and RX power.
To display the alarm information or fault detection parameters about transceiver modules:
Task Command Remarks
