Displaying transceiver module information
To identify transceiver modules, you can use the following command to view the key parameters of
the transceiver modules, including transceiver module type, connector type, central wavelength of
the laser sent, transmission distance, and vendor name or name of the vendor who customizes the
transceiver modules.
To display transceiver module information:
Purpose
Display key parameters of the
transceiver module in a specified
interface
Displaying the alarming information or fault detection
parameters for a transceiver module
The system outputs alarm information for you to locate and troubleshoot faults of transceiver
modules. For the H3C-customized transceiver modules, the system can also monitor the key
parameters, such as temperature, voltage, laser bias current, TX power, and RX power. When these
parameters are abnormal, you can take corresponding measures to prevent transceiver module
faults.
