  2. Cable tester - Wikipedia

    en.wikipedia.org/wiki/Cable_tester

    A cable tester is an electronic device used to verify the electrical connections in a signal cable or other wired assembly. Basic cable testers are continuity testers that verify the existence of a conductive path between ends of the cable, and verify the correct wiring of connectors on the cable. More advanced cable testers can measure the ...

  3. Category 5 cable - Wikipedia

    en.wikipedia.org/wiki/Category_5_cable

    Cable types, connector types and cabling topologies are defined by ANSI/TIA-568. Category 5 cable is nearly always terminated with 8P8C modular connectors (often referred to incorrectly as RJ45 connectors [14] [15] [16]). The cable is terminated in either the T568A scheme or the T568B scheme. The two schemes work equally well and may be mixed ...

  4. Ethernet physical layer - Wikipedia

    en.wikipedia.org/wiki/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 Twisted pair, optical fiber, coaxial cable Network topology Point-to-point, star, bus Major variants

  5. Networking cable - Wikipedia

    en.wikipedia.org/wiki/Networking_cable

    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).

  6. Registered jack - Wikipedia

    en.wikipedia.org/wiki/Registered_jack

    The RJ45S jack is rarely used in telephone applications, and the keyed 8P8C modular plug used for RJ45S mechanically cannot be inserted into an Ethernet port, but a similar plug, the non-keyed 8P8C modular plug – never used for RJ45S – is used in Ethernet networks, and the connector is often, however improperly, referred to as RJ45 in this ...

  7. ISO/IEC 11801 - Wikipedia

    Class C: Up to 16 MHz using Category 3 cable and connectors; Class D: Up to 100 MHz using Category 5e cable and connectors; Class E: Up to 250 MHz using Category 6 cable and connectors; Class E A: Up to 500 MHz using category 6A cable and connectors (Amendments 1 and 2 to ISO/IEC 11801, 2nd Ed.) Class F: Up to 600 MHz using Category 7 cable and ...

  8. Ethernet over twisted pair - Wikipedia

    en.wikipedia.org/wiki/Ethernet_over_twisted_pair

    Cable testers are widely available to check these parameters to determine if a cable can be used with 10BASE-T. These characteristics are expected to be met by 100 meters of 24-gauge unshielded twisted-pair cable. However, with high-quality cabling, reliable cable runs of 150 meters or longer are often achievable and are considered viable by ...

  9. Copper cable certification - Wikipedia

    en.wikipedia.org/wiki/Copper_cable_certification

    An ideal skew is between 25 and 50 nanoseconds over a 100-meter cable. The lower this skew the better; less than 25 ns is excellent, but 45 to 50 ns is marginal. (Traveling between 50% and 80% of the speed of light, an electronic wave requires between 417 and 667 ns to traverse a 100-meter cable.
