2. 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 ...

3. Ethernet crossover cable - Wikipedia

   en.wikipedia.org/wiki/Ethernet_crossover_cable

   A crossover cable may also be used to connect two hubs or two switches on their upstream ports. Because the only difference between the T568A and T568B pin and pair assignments are that pairs 2 and 3 are swapped, a crossover cable may be envisioned as a cable with one modular connector following T568A and the other T568B (see TIA/EIA-568 wiring ...

4. Ethernet over twisted pair - Wikipedia

   en.wikipedia.org/wiki/Ethernet_over_twisted_pair

   The cable must be capable of transmitting 600 MHz for 1000BASE-T1 and 66 MHz for 100BASE-T1. 2.5 Gb/s, 5 Gb/s, and 10 Gb/s over a 15 m single pair is standardized in 802.3ch-2020. [25] In June 2023, 802.3cy added 25 Gb/s speeds at lengths up to 11 m. [26] Similar to PoE, Power over Data Lines (PoDL) can provide up to 50 W to a device. [27]

5. Cable reel - Wikipedia

   en.wikipedia.org/wiki/Cable_reel

   Retractable cable reels are particularly useful for environments where access to electricity or air is needed in a wide variety of places. All retractable hose reels operate using a constant-force spring to provide torsion for the spool, and a ratcheting mechanism to prevent the cable from retracting while it is being used.

6. Registered jack - Wikipedia

   en.wikipedia.org/wiki/Registered_jack

   A cable with a 50-pin connector on one end can support six fully wired 8P8C connectors or Ethernet ports on a patch panel with one spare pair. Alternatively, only the necessary pairs for 10/100 Ethernet can be wired allowing twelve Ethernet ports with a single spare pair. This connector is also used with spring bail locks for SCSI-1 connections.

7. Twinaxial cabling - Wikipedia

   en.wikipedia.org/wiki/Twinaxial_cabling

   Twinaxial cabling, or twinax, is a type of cable similar to coaxial cable, but with two inner conductors in a twisted pair instead of one. [3] Due to cost efficiency it is becoming common in modern (2013) very-short-range high-speed differential signaling applications.
