Cisco Small Form-Factor Pluggable Modules for

Gigabit Ethernet Applications

The industry-standard Cisco

Small Form-Factor Pluggable (SFP) Gigabit Interface

Converter is a hot-swappable input/output device that plugs into a Gigabit Ethernet

port or slot, linking the port with the network (Figures 1, 2 and 3). SFPs can be used

and interchanged on a wide variety of Cisco products and can be intermixed in

combinations of 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-EX,

1000BASE-ZX, or 1000BASE-BX10-D/U on a port-by-port basis.

1000BASE-T SFP for Copper Networks

The 1000BASE-T SFP operates on standard Category 5 unshielded twisted pair copper cabling of up to 100m

(328 ft) link length. Cisco 1000BASE-T SFP modules support 10/100/1000 autonegotiation and Auto MDI/MDIX.

1000BASE-SX SFP for Multimode Fiber Only

The 1000BASE-SX SFP, compatible with the IEEE 802.3z 1000BASE-SX standard, operates on legacy 50 µm

multimode fiber links up to 550 m and on 62.5 µm Fiber Distributed Data Interface (FDDI)-grade multimode fibers

up to 220 m. It can support up to 1km over laser-optimized 50 µm multimode fiber cable.
