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
µ
m
multimode fiber links up to 550 m and on 62.5
µ
m Fiber Distributed Data Interface (FDDI)-grade multimode fibers
up to 220 m. It can support up to 1km over laser-optimized 50
µ
m multimode fiber cable.
