  2. Twisted pair - Wikipedia

    en.wikipedia.org/wiki/Twisted_pair

    Twisted pair cabling is a type of communications cable in which two conductors of a single circuit are twisted together for the purposes of improving electromagnetic compatibility. Compared to a single conductor or an untwisted balanced pair , a twisted pair reduces electromagnetic radiation from the pair and crosstalk between neighboring pairs ...

  3. Ethernet over twisted pair - Wikipedia

    en.wikipedia.org/wiki/Ethernet_over_twisted_pair

    Ethernet over twisted-pair technologies use twisted-pair cables for the physical layer of an Ethernet computer network. They are a subset of all Ethernet physical layers . Early Ethernet used various grades of coaxial cable , but in 1984, StarLAN showed the potential of simple unshielded twisted pair .

  4. Differential signalling - Wikipedia

    en.wikipedia.org/wiki/Differential_signalling

    Differential signalling is a method for electrically transmitting information using two complementary signals. The technique sends the same electrical signal as a differential pair of signals, each in its own conductor. The pair of conductors can be wires in a twisted-pair or ribbon cable or traces on a printed circuit board.

  7. Power over Ethernet - Wikipedia

    en.wikipedia.org/wiki/Power_over_Ethernet

    Each pair of twisted pairs needs to handle a current of up to 600 mA (Type 3) or 960 mA (Type 4). [11] Additionally, support for 2.5GBASE-T, 5GBASE-T and 10GBASE-T is included. [ 12 ] This development opens the door to new applications and expands the use of applications such as high-performance wireless access points and surveillance cameras.

  8. RS-422 - Wikipedia

    en.wikipedia.org/wiki/RS-422

    When used in relation to communications wiring, RS-422 wiring refers to cable made of 2 sets of twisted pair, often with each pair being shielded, and a ground wire. While a double-pair cable may be practical for many RS-422 applications, the RS-422 specification only defines one signal path and does not assign any function to it.

  9. Autonegotiation - Wikipedia

    en.wikipedia.org/wiki/Autonegotiation

    Autonegotiation is a signaling mechanism and procedure used by Ethernet over twisted pair by which two connected devices choose common transmission parameters, such as speed, duplex mode, and flow control. In this process, the connected devices first share their capabilities regarding these parameters and then choose the highest-performance ...
