Identifying pluggable transceivers
As pluggable transceivers are of various types and from different vendors, you can perform the
following configurations to identify main parameters of the pluggable transceivers, including transceiver
type, connector type, central wavelength of the laser sent, transfer distance and vendor name or vendor
name specified.
Follow these steps to identify pluggable transceivers:

z You can use the Vendor Name field in the prompt information of the display transceiver
interface command to identify an anti-spoofing pluggable transceiver customized by H3C. If the
field is H3C, it is considered an H3C-customized pluggable transceiver.
z Electrical label information is also called permanent configuration data or archive information,
which is written to the storage device of a card during device debugging or test. The information
includes name of the card, device serial number, and vendor name or vendor name specified.
Diagnosing pluggable transceivers
The system outputs alarm information for you to diagnose and troubleshoot faults of pluggable
transceivers. Optical transceivers customized by H3C also support the digital diagnosis function, which
enables a transceiver to monitor the main 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 faults.
