Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size. Understanding the characteristics of different types of cable and how they relate to other aspects of a network is necessary for the development of a successful network.
In the 1970s and 1980s, coaxial cable was the preferred LAN medium. But by the late 1980s, data-capable twisted-pair wiring emerged as the predominant network cabling scheme. While twisted-pair wire has cable distance limitations, a hierarchical wiring scheme, initially built around hubs (and more recently switches), overcomes those limitations. Workstations are attached to workgroup hubs/switches in nearby wiring closets and those hubs/switches are attached to wiring hubs/switches at centralized data centers via twisted-pair cable, or via fiber-optic cable over long distances.

| 100BaseTX | Unshielded Twisted Pair | 220 meters |
Today, there are a variety of standards that define cable and component specifications, including the configuration, implementation, performance, conformance, and verification of cabling systems. The most prominent standards are listed here:
United States TIA/EIA-568-A (Telecommunications Industry Association/Electronic Industries Association-568-A), defines how to design, build, and manage a structured wiring system. Note that the specification is also called the EIA/TIA-568 in some references. Refer to "TIA/EIA Structured Cabling Standards" for more information.
International ISO/IEC IS 11801 (International Organization for Standardization/International Engineering Consortium) defines generic cabling for customer premises. It is being used in Europe, Asia, and Africa. See ISO/IEC-11801 Cabling Standards.
Europe Cenelec EN 50173 was derived from ISO 11801 and defines generic cabling and open-market cabling components.
Canada CSA T529-Canadian Standards for Telecommunications Wiring Systems that closely follows the TIA/EIA-568 specifications.
Australia and New Zealand SAA/SNZ HB27:1996. This standard is based on the TIA TSB67 standard. It specifies field testing of balanced copper cabling and the methodology of specifying field tester accuracy
