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.
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 ...
The origin of the "Keystone" module may be traced back to US Patent 4261633 of Aug 27, 1979 for a "Wiring module for telephone jack" - by Amp Incorporated. [1] The module referred to in that patent was affixed by "A pair of diagonally inclined mounting flanges (which) include stepped, panel bearing surfaces .. at the outer free ends thereof."
Category 5 cable is nearly always terminated with 8P8C modular connectors (often referred to incorrectly as RJ45 connectors [14] [15] [16]). The cable is terminated in either the T568A scheme or the T568B scheme. The two schemes work equally well and may be mixed in an installation so long as the same scheme is used on both ends of each cable.
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.
Cat 6 cable can be identified by the printing on the side of the cable sheath. [3] Cable types, connector types and cabling topologies are defined by ANSI/TIA-568.. Cat 6 patch cables are normally terminated in 8P8C modular connectors, using either T568A or T568B pin assignments; performance is comparable provided both ends of a cable are terminated identically.
