The visual difference from the more-common 8P female is subtle. The RJ45S keyed 8P modular connector has only pins 5 and 4 wired for tip and ring (respectively) of a single telephone line, and a "programming" resistor connected to pins 7 and 8. [10] [11] [12]
For example, telephone cables in the UK typically have a BS 6312 (UK standard) plug at the wall end and a 6P4C or 6P2C modular connector at the telephone end: this latter may be wired as per the RJ11 standard (with pins 3 and 4), or it may be wired with pins 2 and 5, as a straight-through cable from the BT plug (which uses pins 2 and 5 for the ...
The original RJ45S [18] [24] keyed 8P2C modular connector, obsolete today, had pins 5 and 4 wired for tip and ring of a single telephone line and pins 7 and 8 shorting a programming resistor. Electronics catalogs commonly advertise 8P8C modular connectors as RJ45.
The colors of the wire pairs in the cable, in order, are blue (for pair 1), orange, green, and brown (for pair 4). Each pair consists of one conductor of solid color and a second conductor, which is white with a stripe of the other color. The difference between the T568A and T568B pinouts is that pairs 2 and 3 (orange and green) are exchanged.
Several other types of cable existed such as type 2, and type 3 cable. [24] In later implementations of Token Ring, Cat 4 cabling was also supported, so 8P8C (RJ45) connectors were used on both of the MAUs, CAUs and NICs; with many of the network cards supporting both 8P8C and DE-9 for backwards compatibility. [20]
The most common type uses Category 5 cables (four twisted pairs with 100 ohm impedance) between 8P8C (colloquially and incorrectly called RJ45) room sockets and a central patch panel. The A and B wires of an analogue phone line appear in a structured cabling system usually on the centre pins of the 8P8C connector (pins 4 and 5; the blue/white ...
GG45 (GigaGate 45) and ARJ45 (Augmented RJ45) are two related connectors for Category 7, Category 7 A, and Category 8 telecommunication cabling. The GG45 interface and related implementations are developed and sold by Nexans S.A. , while the ARJ45 interface and related implementations are developed and sold by Bel Fuse Inc.
Uses PAM-3 modulation at 66.7 MBd over a single, bi-directional twisted pair of up to 15 m; three bits are encoded as two ternary symbols. It is intended for automotive applications. 100BaseVG: 802.12-1994: 8P8C: Standardized by a different IEEE 802 subgroup, 802.12, because it used a different, more centralized form of media access (demand ...
