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.

Table 4-1Commonly used pluggable transceivers

For pluggable transceivers supported by the device, refer to 3Com WX3000 Series Unified Switches Installation Manual.

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.
