SFP and SFP+ Transceiver Modules

The SFP and SFP+ transceiver modules provide copper or fiber-optic connections to other devices. These
transceiver modules are field-replaceable and provide the uplink interfaces when installed in an SFP module
slot. The SFP modules have LC connectors for fiber-optic connections or RJ-45 connectors for copper
connections.
