Verifying and diagnosing transceiver modules
At present, there are three types of commonly used transceiver modules, as shown in Table 19 . They can
be further divided into optical transceiver modules and electrical transceiver modules based on
transmission medium.

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:
Task Command
Display key parameters of the transceiver
module in a specified interface.
display transceiver interface [ interface-type interface-number ]
Display part of the electrical label
information about the transceiver module
in a specified interface.
display transceiver manuinfo interface [ interface-type
interface-number ]
# Display the main parameters of the transceiver module plugged in interface GigabitEthernet 3/0/19.
<Sysname> display transceiver interface Gigabitethernet 3/0/19
