  2. 25-pair color code - Wikipedia

    en.wikipedia.org/wiki/25-pair_color_code

    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. For example, a 900-pair cable has the first 600 pairs in 24 groups of 25 pairs in a white binder, and the remaining 300 pairs in 12 groups of 25 pairs wrapped in a red binder. [5] [6]

  3. Category 5 cable - Wikipedia

    en.wikipedia.org/wiki/Category_5_cable

    Category 5 cable is used in structured cabling for computer networks such as Ethernet over twisted pair. The cable standard prescribes performance parameters for frequencies up to 100 MHz and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), 1000BASE-T (Gigabit Ethernet), and 2.5GBASE-T. 10BASE-T and 100BASE-TX Ethernet connections require ...

    Category 7 S/FTP cable. Class F channel and Category 7 cable are backward compatible with Class D/Category 5e and Class E/Category 6. Class F features even stricter specifications for crosstalk and system noise than Class E. To achieve this, shielding was added for individual wire pairs and the cable as a whole. Unshielded cables rely on the ...

    Common for current LANs. Superseded by Cat 5e, but most Cat 5 cables meet Cat 5e standards. [18] Limited to 100 m between equipment. Cat 5e: UTP, [18] F/UTP, U/FTP [19] 100 MHz [18] 1000BASE-T, 2.5GBASE-T [18] Enhanced Cat 5. Common for current LANs. Same construction as Cat 5, but with better testing standards. [18] Limited to 100m between ...

  6. Ethernet physical layer - Wikipedia

    en.wikipedia.org/wiki/Ethernet_physical_layer

    Ethernet physical layer. A standard 8P8C (often called RJ45) connector used most commonly on category 5 cable, one of the types of cabling used in Ethernet networks. Standard. IEEE 802.3 (1983 onwards) Physical media. Coaxial cable, twisted pair, optical fiber. Network topology.

  7. Fast Ethernet - Wikipedia

    en.wikipedia.org/wiki/Fast_Ethernet

    Fast Ethernet is an extension of the 10-megabit Ethernet standard. It runs on twisted pair or optical fiber cable in a star wired bus topology, similar to the IEEE standard 802.3i called 10BASE-T, itself an evolution of 10BASE5 (802.3) and 10BASE2 (802.3a). Fast Ethernet devices are generally backward compatible with existing 10BASE-T systems ...

  8. Copper cable certification - Wikipedia

    en.wikipedia.org/wiki/Copper_cable_certification

    Copper cable certification. In copper twisted pair wire networks, copper cable certification is achieved through a thorough series of tests in accordance with Telecommunications Industry Association (TIA) or International Organization for Standardization (ISO) standards. These tests are done using a certification-testing tool, which provide ...

  9. Ethernet over twisted pair - Wikipedia

    en.wikipedia.org/wiki/Ethernet_over_twisted_pair

    Since common Category 5 cable has four pairs, it is possible to use the spare pairs (pins 4–5, 7–8) in 10- and 100-Mbit/s configurations for other purposes. The spare pairs may be used for power over Ethernet (PoE), for two plain old telephone service (POTS) lines, or for a second 10BASE-T or 100BASE-TX connection.
