  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 ...

  4. 25-pair color code - Wikipedia

    en.wikipedia.org/wiki/25-pair_color_code

    In cables of more than 600 pairs, each of the 600-pair super binder group bundles is wrapped with a mylar binder ribbon, or string, matching the "tip" colors of the color code, starting with white. The pattern then starts over with the first 25-pair group as white/blue, and continues indefinitely, in multiples of 600 pairs or parts thereof.

  5. Category 5 cable - Wikipedia

    en.wikipedia.org/wiki/Category_5_cable

    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).

  6. ANSI/TIA-568 - Wikipedia

    en.wikipedia.org/wiki/ANSI/TIA-568

    A cable terminated according to T568A on one end and T568B on the other is a crossover cable when used with the earlier twisted-pair Ethernet standards that use only two of the pairs because the pairs used happen to be pairs 2 and 3, the same pairs on which T568A and T568B differ. Crossover cables are occasionally needed for 10BASE-T and ...

  7. Ethernet physical layer - Wikipedia

    en.wikipedia.org/wiki/Ethernet_physical_layer

    Uses a single, bi-directional twisted pair in full duplex mode only; cables specified for a reach of 15 m (automotive link segment) or 40 m (optional link segment), intended for automotive and industrial applications; it uses 80B/81B encoding in the PCS, PAM-3 signalling at 750 MBd (three bits transmitted as two ternary symbols) and includes ...

  8. Category 6 cable - Wikipedia

    en.wikipedia.org/wiki/Category_6_cable

    A Cat 6 patch cable, terminated with 8P8C modular connectors. Category 6 cable (Cat 6) is a standardized twisted pair cable for Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards. Cat 6 must meet more stringent specifications for crosstalk and system noise than Cat 5 and ...

  9. 20-pair colour code (Australia) - Wikipedia

    en.wikipedia.org/wiki/20-pair_colour_code...

    The 20-pair colour code is a colour code used in Australia to identify individual conductors in a kind of electrical telecommunication wiring for indoor use, known as twisted pair cables. The colours are applied to the insulation that covers each conductor. The first colour is chosen from one group of five colours.
