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 alarm information or fault detection parameters for a transceiver module:
