Ansi-eia-tia-568 meaning

A United States industry standard published jointly by ANSI and the EIA/TIA specifying a generic structured cabling system for commercial buildings. Intended to support a multivendor environment, the standard specifies cable physical attributes and performance characteristics for unshielded twisted pair (UTP), shielded twisted pair (STP), and screened twisted pair (ScTP) cabling categories.The initial standard was released in 1985, and has been modified and updated several times since. Category (Cat) 3, 4, 5, 6, and 7 cables have been defined. Cat 1 and Cat 2 are not formally defined under this particular standard.The most recent (as of Spring 2007) and most capable standard is Cat 7, which supports bandwidth of up to 600 MHz and data rates up to 10 Gbps. The standards also have been internationalized as ISO/IEC 11801. See also ANSI, Cat, and EIA/TIA.
