,Cisco GLC-SX-MMD 1000BASE-SX SFP transceiver module, MMF,
The GLC-SX-MMD 1000BASE-SX SFP is made 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. 850-nm wavelength,
extended operating temperature range and DOM support, dual LC/PC
This Figure shows the appearance of GLC-SX-MMD.
The table provides cabling specifications for the SFPs that you
install in the Gigabit Ethernet port.
Note that all SFP ports have LC-type connectors, and the minimum
cable distance for all SFPs listed (multimode and single-mode
fiber) is 6.5 feet (2 m).

*A mode-conditioning patch cord, as specified by the IEEE standard,
is required regardless of the span length. Note how the mode
conditioning patch cord for 62.5-μm fibers has a different
specification from the mode-conditioning patch cord for 50-μm
