  2. Twisted pair - Wikipedia

    en.wikipedia.org/wiki/Twisted_pair

    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 ...

    The most common form of installation is over twisted pair medium. KNX is an approved standard by the following organisations, : [1] International standard (ISO/IEC 14543-3) European standard (CENELEC EN 50090 and CEN EN 13321–1) US standard (ANSI/ASHRAE 135) China Guobiao (GB/T 20965)

  4. 110 block - Wikipedia

    en.wikipedia.org/wiki/110_block

    A 110 punch block. A 110 block is a type of punch-down block used to terminate runs of on-premises wiring in a structured cabling system. The designation 110 is also used to describe a type of insulation displacement contact (IDC) connector used to terminate twisted pair cables, [1] which uses a punch-down tool similar to the type used for the older 66 block.

  5. Home wiring - Wikipedia

    en.wikipedia.org/wiki/Home_wiring

    Power and telecommunication services generally require entry points into the home and a location for connection equipment. For electric power supply, a cable is run either overhead or underground into a distribution board in the home. A distribution board, or circuit breaker panel, is typically a metal box mounted on a wall of the home.

  6. Structured cabling - Wikipedia

    en.wikipedia.org/wiki/Structured_cabling

    Structured cabling is the design and installation of a cabling system that will support multiple hardware uses and be suitable for today's needs and those of the future. With a correctly installed system, current and future requirements can be met, and hardware that is added in the future will be supported. [1]

  7. Ethernet over twisted pair - Wikipedia

    en.wikipedia.org/wiki/Ethernet_over_twisted_pair

    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 .

  9. RS-422 - Wikipedia

    en.wikipedia.org/wiki/RS-422

    When used in relation to communications wiring, RS-422 wiring refers to cable made of 2 sets of twisted pair, often with each pair being shielded, and a ground wire. While a double-pair cable may be practical for many RS-422 applications, the RS-422 specification only defines one signal path and does not assign any function to it.
