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. Twisted pair - Wikipedia

   en.wikipedia.org/wiki/Twisted_pair

   A solid-core cable uses one solid wire per conductor and in a four-pair cable, there would be a total of eight solid wires. [18] Stranded cable uses multiple wires wrapped around each other in each conductor and in a four-pair with seven strands per conductor cable, there would be a total of 56 wires (2 per pair × 4 pairs × 7 strands).

4. Modular connector - Wikipedia

   en.wikipedia.org/wiki/Modular_connector

   Only lines 1 and 2 have electrical compatibility, with T568A wiring, and only line 1 with T568B wiring, because Ethernet-compatible pin assignments split the third pair of RJ25 across two separate cable pairs, rendering that pair unusable by an analog phone. (With T568B wiring, a telephone may connect to line 3 as line 2.) Both the third and ...

5. 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 ...

6. Ethernet over twisted pair - Wikipedia

   en.wikipedia.org/wiki/Ethernet_over_twisted_pair

   A 100BASE-TX transmitter sends three differential voltages, +1 V, 0 V, or −1 V. [15] Unlike earlier Ethernet standards using broadband and coaxial cable, such as 10BASE5 (thicknet) and 10BASE2 (thinnet), 10BASE-T does not specify the exact type of wiring to be used but instead specifies certain characteristics that a cable must meet. This was ...

7. Structured cabling - Wikipedia

   en.wikipedia.org/wiki/Structured_cabling

   Regardless of copper cable type (Cat 5e/6/6A), the maximum distance is 90 m for the permanent link installation, plus an allowance for a combined 10 m of patch cords at the ends. Cat 5e and Cat 6 can both effectively run power over Ethernet (PoE) applications up to 90 m. However, due to greater power dissipation in Cat 5e cable, performance and ...
