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 command in any view:
Task | Command |
---|---|
Display key parameters of the transceiver in a specified interface | display transceiver interface [ interface-type interface-number ] |
Display part of the electrical label information of transceiver in a specified interface | display transceiver manuinfo interface [ interface-type interface-number ] |
# Display the main parameters of the transceiver plugged in interface GigabitEthernet 3/0/3.

Transfer distance(xx) | Transfer distance, where "xx" represents the distance unit: km (kilometers) for single-mode transceivers and m (meters) for other transceivers. If the transceiver supports multiple transfer medium, every two values of the transfer distance are separated by a comma. The transfer medium is included in the bracket following the transfer distance value. The following are the transfer media:
