Verifying and diagnosing transceiver modules
Verifying transceiver modules
You can verify the genuineness of a transceiver module in the following ways:
• Display the key parameters of a transceiver module, including its transceiver type, connector type,
central wavelength of the transmit laser, transfer distance and vendor name.
• Display its electronic label. The electronic label is a profile of the transceiver module and contains
the permanent configuration including the serial number, manufacturing date, and vendor name.
The data is written to the storage component during debugging or testing.
To verify transceiver modules, perform the following commands in any view:
Task Command
Display key parameters of the pluggable transceiver.
display transceiver interface [ interface-type
interface-number ] [ | { begin | exclude | include }
regular-expression ]
Display the electrical label information of the
pluggable transceiver.
display transceiver manuinfo interface [ interface-type
interface-number ] [ | { begin | exclude | include }
regular-expression ]
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 diagnose transceiver modules, perform the following commands in any view:
Task Command
Display the current alarm information of the
pluggable transceiver
display transceiver alarm interface [ interface-type
interface-number ] [ | { begin | exclude | include }
regular-expression ]
