Cisco 1000 BASE-T SFP Transceiver Module

The small form-factor pluggable (SFP) Gigabit interface converter (GBIC) is a hot-swappable input/output device that plugs into a Gigabit Ethernet port or slot, linking the port with the network. The Cisco SFP provides full-duplex Gigabit Ethernet connectivity to high-end workstations and between wiring closets over existing copper network infrastructure.
