Verifying and diagnosing transceiver modules
Introduction to transceiver modules
There are two types of commonly used transceiver modules, as shown in Table 22 . They can be further
divided into optical transceiver modules and electrical transceiver modules based on transmission
medium.

Verifying transceiver modules
To verify transceiver modules, you can use the following commands to view the key parameters of the
transceiver modules, including transceiver module type, connector type, central wavelength of the laser
sent, transfer distance and vendor name.
To display the transceiver module information:
Task Command Remarks
Display key parameters of the
transceiver module in a
specified interface.
display transceiver interface [ interface-type
interface-number ] Available for all transceiver
modules.
Display part of the electrical
label data for the transceiver
module in a specified interface.
display transceiver manuinfo interface
[ interface-type interface-number ] Available for all transceiver
modules.
# Display the main parameters of the transceiver module plugged in interface GigabitEthernet 3/1/1.
