Identifying and Diagnosing Pluggable Transceivers
Introduction to pluggable transceivers
At present, four types of pluggable transceivers are commonly used, and they can be divided into
optical transceivers and electrical transceivers based on transmission media as shown in
Table 4-1
.

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:
