1000Base-SX (1000 Mbps; Baseband; Short range)

The IEEE 802.3z media specifications for

Gigabit Ethernet (GbE) transmission over multimode fiber (MMF) with a core diameter of either 50µ or 62.5µ, using a wavelength of 850 nm.The modal bandwidth ranges from 160 MHz/km to 500 MHz/km, and maximum distance ranges from 220 meters to 550 meters. The letter X indicates that 8B/10B signal encoding technique is used. See 802.3z for comparisons. See also 8B/10B, IEEE, MMF, modal bandwidth, and wavelength.
