A cable color scheme, known as even-count color code, is determined for 25 pairs of conductors as follows: [8] For each ring, the primary, more prominent color is chosen from the set blue, orange, green, brown, and slate, in that order, and the secondary, thinner stripe color from the set of white, red, black, yellow, and violet colors, in that ...
A cable wired as T568A at one end and wired as T568B at the other end (Tx and Rx pairs reversed) is an Ethernet crossover cable. Before the widespread acceptance of auto MDI-X capabilities, a crossover cable was needed to interconnect similar network equipment (such as Ethernet hubs to Ethernet hubs). Crossover cables are sometimes still used ...
A cable terminated according to T568A on one end and T568B on the other is a crossover cable when used with the earlier twisted-pair Ethernet standards that use only two of the pairs because the pairs used happen to be pairs 2 and 3, the same pairs on which T568A and T568B differ. Crossover cables are occasionally needed for 10BASE-T and ...
A standard 8P8C (often called RJ45) connector used most commonly on category 5 cable, one of the types of cabling used in Ethernet networks Standard IEEE 802.3 (1983 onwards) Physical media Twisted pair, optical fiber, coaxial cable Network topology Point-to-point, star, bus Major variants
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. [2]
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.
A crossover cable may also be used to connect two hubs or two switches on their upstream ports. Because the only difference between the T568A and T568B pin and pair assignments are that pairs 2 and 3 are swapped, a crossover cable may be envisioned as a cable with one modular connector following T568A and the other T568B (see TIA/EIA-568 wiring ...
A patch cable, patch cord or patch lead is an electrical or fiber-optic cable used to connect ("patch in") one electronic or optical device to another for signal routing. Devices of different types (e.g., a switch connected to a computer, or a switch to a router ) are connected with patch cords.
