Twisted pair cabling is a type of communications cable in which two conductors of a single circuit are twisted together for the purposes of improving electromagnetic compatibility. Compared to a single conductor or an untwisted balanced pair , a twisted pair reduces electromagnetic radiation from the pair and crosstalk between neighboring pairs ...
Ethernet over twisted-pair technologies use twisted-pair cables for the physical layer of an Ethernet computer network. They are a subset of all Ethernet physical layers.. Early Ethernet used various grades of coaxial cable, but in 1984, StarLAN showed the potential of simple unshielded twisted pair.
Different types of network cables, such as coaxial cable, optical fiber cable, and twisted pair cables, are used depending on the network's topology, protocol, and size. The devices can be separated by a few meters (e.g. via Ethernet ) or nearly unlimited distances (e.g. via the interconnections of the Internet ).
Category 5 cable that is partially stripped and showing its four twisted pairs (eight wires). Category 5 cable (Cat 5) is a twisted pair cable for computer networks.Since 2001, the variant commonly in use is the Category 5e specification (Cat 5e).
Unifying Theories of Programming, in computer science Unshielded twisted pair , a type of communications cable Micro Transport Protocol (μTP or uTP), a computer network protocol
A category 3 cable. Category 3 cable, commonly known as Cat 3 or station wire, and less commonly known as VG or voice-grade [1] (as, for example, in 100BaseVG), is an unshielded twisted pair (UTP) cable used in telephone wiring.
The standard defines categories of shielded and unshielded twisted pair cable systems, with different levels of performance in signal bandwidth, insertion loss, and cross-talk. Generally increasing category numbers correspond with a cable system suitable for higher rates of data transmission.
Twisted-pair cable 1BASE5: 802.3e-1987 (12) 8P8C (IEC 60603-7) 250 m voice-grade Also called StarLAN. Operated at 1 Mbit/s over twisted pair to an active hub, star topology. Although a commercial failure, 1BASE5 pioneered the use of twisted-pair cabling and defined the architecture for all subsequent Ethernet evolution on that medium ...
