GLC-SX-MM D Overview The GLC-SX-MM D 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 mu,m multimode fiber links up to 550 m and on 62.5 mu,m Fiber Distributed Data Interface (FDDI)-grade multimode fibers up to 220 m. It can support up to 1km over laser-optimized 50 mu,m multimode fiber cable. 850-nm wavelength, extended operating temperature range and DOM support, dual LC/PC connector.
