Verifying and diagnosing transceiver modules
This section describes how to verify and diagnose transceiver modules.
NOTE:
Support for the transceiver modules and the transceiver module type depends on your device model.
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, execute the following commands in any view:
Task Command
