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 684.

For pluggable transceivers supported by Switch 7750 Ethernet switches, refer to
3Com Switch 7750 Family 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.
Follow these steps to identify pluggable transceivers:
To do...
Display main parameters of
the pluggable transceiver(s)
Display part of the electrical
label information of the
anti-spoofing transceiver(s)
customized by 3Com
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 3Com. If the field is 3Com, it is considered an
3Com-customized pluggable transceiver.
Electrical label information is also called permanent configuration data or
■
archive information, which is written to the storage device of a module during
device debugging or test. The information includes name of the module,
device serial number, and vendor name or vendor name specified.
