1000Base-LX (1000 Mbps; Baseband; Long range)

The IEEE 802.3z media specifications for Giga-

bit Ethernet (GbE) transmission over multimode fiber (MMF) and single-mode fiber (SMF), using a wavelength of 1300 nm and 1310 nm, respectively. The modal bandwidth for the MMF options ranges from 400 MHz/km to 500 MHz/km, and maximum distance is 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.
