RJ45 is often incorrectly used when referring to an 8P8C connector used for ANSI/TIA-568 T568A and T568B and Ethernet, however, the plug used for RJ45 is both mechanically and electrically incompatible with any Ethernet port: it cannot fit into an Ethernet port, and it is wired in a way that is incompatible with Ethernet. The connector commonly ...
Right: RJ45 male connector (with key) Although commonly referred to as RJ45 in the context of Ethernet and category 5 cables, RJ45 originally referred to a specific wiring configuration of an 8P8C connector. [14] [15] [16] The original telephone-system-standard RJ45 plug has a key that excludes insertion in an un-keyed 8P8C socket. [17]
A telephone jack and a telephone plug are electrical connectors for connecting a telephone set or other telecommunications apparatus to the telephone wiring inside a building, establishing a connection to a telephone network. The plug is inserted into its counterpart, the jack, which is commonly affixed to a wall or baseboard. The standards for ...
The standard specifies how to connect eight-conductor 100-ohm balanced twisted-pair cabling, such as Category 5 cable, to 8P8C modular connectors (often referred to as RJ45 connectors). The standard defines two alternative pinouts: T568A and T568B. ANSI/TIA-568 recommends the T568A pinout for horizontal cables.
The 8P8C modular connector pinout matches the conductor pairing scheme used by Category 5 (Cat5) twisted pair patch cables. The avoidance of pins 4 and 5 helps to prevent equipment damage, if the cabling is accidentally plugged into a single-line public switched telephone network phone jack.
The same connector is used for Intel's Thunderbolt connector, developed in cooperation with Apple. HDBaseT ( 8P8C modular connector ) Used for transmission of uncompressed high-definition video, audio, Ethernet , high-power over cable and various controls, via a 100 m Cat5e/Cat6 cable with 8P8C modular connectors of the type commonly used for ...
BS 6312 431A plug, colloquially a British Telecom 4-wire male plug. British telephone sockets were introduced in their current plug and socket form on 19 November 1981 by British Telecom to allow subscribers to connect their own telephones. The connectors are specified in British Standard BS 6312.
GG45 is a variant of ARJ45 that allows for cables terminated with male 8P8C (AKA RJ45) connectors to be plugged into GG45 jacks. However, GG45 cables cannot plug into 8P8C jacks as a protrusion on the socket is designed to activate a switch on the jack for the alternative contact positions.
