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]
The height of the plug's insertion area is 0.260 inches (6.60 mm) and the contacts are 0.040 inches (1.02 mm) apart (contact pitch), so the width is dependent on the number of pin positions. [ 7 ] [ 8 ] However, not all plugs from all manufacturers have this capability, and some jack manufacturers warn that their jacks are not designed to ...
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 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.
Class II: Up to 2 GHz (2000 MHz) using Category 8.2 cable and connectors (ISO/IEC 11801-1, Edition 1.0 2017-11) The standard link impedance is 100 Ω. (The older 1995 version of the standard also permitted 120 Ω and 150 Ω in Classes A−C, but this was removed from the 2002 edition.)
The connectors have the disadvantage of being quite bulky, requiring at least 3 cm × 3 cm (1.2 in × 1.2 in) panel space, and being relatively fragile. The advantages of the connectors being that they are genderless and have superior shielding over standard unshielded 8P8C. Connectors at the computer were usually DE-9 female. Several other ...
Typically it will have 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 line, unlike RJ11, which uses pins 3 and 4).
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.
