There are five physical layer standards for Gigabit Ethernet using optical fiber (1000BASE-X), twisted pair cable (1000BASE-T), or shielded balanced copper cable (1000BASE-CX). The IEEE 802.3z standard includes 1000BASE-SX for transmission over multi-mode fiber, 1000BASE-LX for transmission over single-mode fiber, and the nearly obsolete 1000BASE-CX for transmission over shield. OverviewIn, Gigabit Ethernet (GbE or 1 GigE) is the transmission of at a rate of a. The most popular variant, 1000BASE-T, is defined by the IEEE 802.3ab st. was the result of research conducted at in the early 1970s, and later evolved into a widely implemented and protocol. increased the speed from 10 to 100 meg. IEEE 802.3ab is the original standard for Gigabit Ethernet over twisted-pair wiring, known as 1000BASE-T. Each 1000BASE-T network segment is recommended to be a maximum length of 100 meters.
