1000BASE-T uses all four pairs bi-directionally using hybrid circuits and cancellers. [16] Data is encoded using 4D-PAM5; four dimensions using pulse-amplitude modulation (PAM) with five voltages , −2 V, −1 V, 0 V, +1 V, and +2 V. [ 17 ] While +2 V to −2 V may appear at the pins of the line driver, the voltage on the cable is nominally +1 ...
1000BASE-T (also known as IEEE 802.3ab) is a standard for Gigabit Ethernet over twisted-pair wiring. Each 1000BASE-T network segment is recommended to be a maximum length of 100 meters (330 feet), [5] [a] and must use Category 5 cable or better (including Cat 5e and Cat 6).
It was targeted at the installed base of 10 Mbit/s fiber networks. TIA 1000BASE-TX—Promoted by the Telecommunications Industry Association, it was a commercial failure. 1000BASE-TX uses a simpler protocol than the official 1000BASE-T standard so the electronics can be cheaper, but requires Category 6 cable.
The line encoding used by 10GBASE-T is the basis for the newer and slower 2.5GBASE-T and 5GBASE-T standard, implementing a 2.5 or 5.0 Gbit/s connection over existing category 5e or 6 cabling. [51] Cables that will not function reliably with 10GBASE-T may successfully operate with 2.5GBASE-T or 5GBASE-T if supported by both ends.
In 1987 SynOptics introduced the first twisted-pair Ethernet at 10 Mbit/s in a star-wired cabling topology with a central hub, later called LattisNet. [16] [35]: 29 [42] These evolved into 10BASE-T, which was designed for point-to-point links only, and all termination was built into the device. This changed repeaters from a specialist device ...
The two resulting 3-digit base-3 symbols were sent in parallel over three pairs using 3-level pulse-amplitude modulation (PAM-3). 100BASE-T4 was not widely adopted but some of the technology developed for it is used in 1000BASE-T. [5] Very few hubs were released with 100BASE-T4 support.
The competing MGBASE-T Alliance, stating the same faster Gigabit Ethernet objectives, was founded in December 2014. [15] In contrast to NBASE-T, the MGBASE-T said that their specifications would be open source. [16] IEEE 802.3's "2.5G/5GBASE-T Task Force" started working on the 2.5GBASE-T and 5GBASE-T standards in March 2015. [17]
