  2. 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 ...

  3. Category 5 cable - Wikipedia

    en.wikipedia.org/wiki/Category_5_cable

    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). The cable standard provides performance of up to 100 MHz and is suitable for most varieties of Ethernet over twisted pair up to 2.5GBASE-T [1][2][3][4] but more commonly runs at 1000BASE-T ...

  4. Structured cabling - Wikipedia

    en.wikipedia.org/wiki/Structured_cabling

    Structured cabling network diagram. 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]

  5. Ethernet over twisted pair - Wikipedia

    en.wikipedia.org/wiki/Ethernet_over_twisted_pair

    Most Ethernet cables are wired straight-through (pin 1 to pin 1, pin 2 to pin 2, and so on). In some instances, the crossover form (receive to transmit and transmit to receive) may still be required. Cables for Ethernet may be wired to either the T568A or T568B termination standards at both ends of the cable. Since these standards differ only ...

  6. 25-pair color code - Wikipedia

    en.wikipedia.org/wiki/25-pair_color_code

    If looking at the cable's core and the switch is in that direction, the groups are counted counter-clockwise. If the cable is the field side, the count is clockwise. There are indicators on the mylar ribbons to know where to begin for each layer and a diagram for the different cable sizes should be readily available for reference. [5] [6]

  7. Electrical termination - Wikipedia

    en.wikipedia.org/wiki/Electrical_termination

    In electronics, electrical termination is the practice of ending a transmission line with a device that matches the characteristic impedance of the line. Termination prevents signals from reflecting off the end of the transmission line. Reflections at the ends of unterminated transmission lines cause distortion, which can produce ambiguous ...

  8. IDC (electrical connector) - Wikipedia

    en.wikipedia.org/wiki/IDC_(electrical_connector)

    Pin 1 is typically indicated on the body of the connector by a red or raised "V" mark. The corresponding wire in a ribbon cable is usually indicated by red coloration, a raised molded ridge, or markings printed onto the cable insulation. On the connector pin 2 is opposite pin 1, pin 3 is next to pin 1 along the length of the connector, and so on.

  9. Pothead - Wikipedia

    en.wikipedia.org/wiki/Pothead

    Pothead. A pothead is a type of insulated electrical terminal used for transitioning between overhead line and underground high-voltage cable or for connecting overhead wiring to equipment like transformers. [1] Its name comes from the process of potting or encapsulation of the conductors inside the terminal's insulating bushing.
