The first two early designs of twisted-pair networking were StarLAN, standardized by the IEEE Standards Association as IEEE 802.3e in 1986, at one megabit per second, [7] and LattisNet, developed in January 1987, at 10 megabit per second.
RJ45 is often incorrectly used when referring to an 8P8C connector used for ANSI/TIA-568 T568A and T568B and Ethernet, however, the plug used for RJ45 is both mechanically and electrically incompatible with any Ethernet port: it cannot fit into an Ethernet port, and it is wired in a way that is incompatible with Ethernet. The connector commonly ...
IEEE 802.3bz, NBASE-T and MGBASE-T are standards released in 2016 for Ethernet over twisted pair at speeds of 2.5 and 5 Gbit/s.These use the same cabling as the ubiquitous Gigabit Ethernet, yet offer higher speeds.
100BASE-T is any of several Fast Ethernet standards for twisted pair cables, [dubious – discuss] including: 100BASE-TX (100 Mbit/s over two-pair Cat5 or better cable), 100BASE-T4 (100 Mbit/s over four-pair Cat3 or better cable, defunct), 100BASE-T2 (100 Mbit/s over two-pair Cat3 or better cable, also defunct).
Inherently half-duplex, it needed four pairs in a Cat-3 cable. Now obsolete, the standard has been withdrawn in 2001. HDMI Ethernet Channel: HDMI 1.4 (2009) HDMI: HEC uses a hybrid to mix and separate 100BASE-TX's transmit and receive signals through a single twisted pair. Fiber-optical cable 100BASE‑FX: 802.3u-1995 (24, 26) ST, SC
DMX512-A (ANSI E1.11-2008) defined the use of eight-pin modular (8P8C, or "RJ-45") connectors for fixed installations where regular plugging and unplugging of equipment is not required. Several manufacturers used other pinouts for RJ-45 connectors prior to this inclusion in the standard.
1000BASE-T capable network interface card made by Intel, which connects to the computer via PCI-X. 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).
GG45 (GigaGate 45) and ARJ45 (Augmented RJ45) are two related connectors for Category 7, Category 7 A, and Category 8 telecommunication cabling. The GG45 interface and related implementations are developed and sold by Nexans S.A. , while the ARJ45 interface and related implementations are developed and sold by Bel Fuse Inc.
