Identifying and Diagnosing Pluggable Transceivers

Introduction to pluggable transceivers

At present, four types of pluggable transceivers are commonly used, as shown in
be further divided into optical transceivers and electrical transceivers based on transmission medium.

Identifying pluggable transceivers

As pluggable transceivers are of various types and from different vendors, you can use the following
commands to view the key parameters of the pluggable transceivers, including transceiver type,
connector type, central wavelength of the laser sent, transfer distance and vendor name or name of the
vendor who customizes the transceivers to identify the pluggable transceivers.
Follow these steps to identify pluggable transceivers:
