  2. 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 ...

    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 ...

    Inherently half-duplex, it needed four pairs in a Cat-3 cable. Now obsolete, the standard has been withdrawn in 2001. HDMI Ethernet Channel: HDMI 1.4 (2009) HDMI: HEC uses a hybrid to mix and separate 100BASE-TX's transmit and receive signals through a single twisted pair.

    Ethernet was able to adapt to market needs, and with 10BASE2 shift to inexpensive thin coaxial cable, and from 1990 to the now-ubiquitous twisted pair with 10BASE-T. By the end of the 1980s, Ethernet was clearly the dominant network technology. [4]

    en.wikipedia.org/wiki/DMX512

    DMX512-A (ANSI E1.11-2008) defined the use of eight-pin modular (8P8C, or "RJ-45") connectors for fixed installations where regular plugging and unplugging of equipment is not required. Several manufacturers used other pinouts for RJ-45 connectors prior to this inclusion in the standard.
