GLC-SX-MMD Overview
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 connector.
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).
