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:
