The physical-layer specifications of the Ethernet family of computer network standards are published by the Institute of Electrical and Electronics Engineers (IEEE), which defines the electrical or optical properties and the transfer speed of the physical connection between a device and the network or between network devices.
Cat 6 cable can be identified by the printing on the side of the cable sheath. [3] Cable types, connector types and cabling topologies are defined by ANSI/TIA-568.. Cat 6 patch cables are normally terminated in 8P8C modular connectors, using either T568A or T568B pin assignments; performance is comparable provided both ends of a cable are terminated identically.
The first types of small modular telephone connectors were created by AT&T in the mid-1960s for the plug-in handset and line cords of the Trimline telephone. [1] Driven by demand for multiple sets in residences with various lengths of cords, the Bell System introduced customer-connectable part kits and telephones, sold through PhoneCenter stores in the early 1970s.

IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet.The standards are produced by the working group of the Institute of Electrical and Electronics Engineers (IEEE).
FC-1 – Transmission Protocol, which implements line coding of signals; FC-0 – physical layer , defined by Fibre Channel Physical Interfaces standard, includes cabling, connectors etc.; Fibre Channel products are available at 1, 2, 4, 8, 10, 16 and 32 and 128 Gbit/s ; these protocol flavors are called accordingly 1GFC, 2GFC, 4GFC, 8GFC ...
In computer networking, Gigabit Ethernet (GbE or 1 GigE) is the term applied to transmitting Ethernet frames at a rate of a gigabit per second. The most popular variant, 1000BASE-T , is defined by the IEEE 802.3ab standard.
Class I channel (Category 8.1 cable): minimum cable design U/FTP or F/UTP, fully backward compatible and interoperable with Class E A (Category 6 A) using 8P8C connectors; Class II channel ( Category 8.2 cable): F/FTP or S/FTP minimum, interoperable with Class F A (Category 7 A ) using TERA or GG45 .
For example, RJ11 and RJ14 use female six-position modular connectors, and RJ21 uses a 25-pair (50-pin) miniature ribbon connector. RJ11 uses two conductors in a six-position female modular connector, so can be made with any female six-position modular connector, while RJ14 uses four, so can be made with either a 6P4C or a 6P6C connector.
