Ethernet Cable Twisted Pair Cable Diagram

Ethernet cable utp rj45 wiring diagram there are two standards that are used for rj45 connector wiring.

Ethernet cable twisted pair cable diagram. As there are four pairs of copper wires inside a length of cat5e cable the cable pinouts should be carefully managed. Both standards define the t 568a and t 568b pin outs for using unshielded twisted pair cable and rj 45 connectors for ethernet connectivity. Unshielded twisted pair utp cables are found in many ethernet networks and telephone systems. They are a subset of all ethernet physical layers.

Both standards can be used to make ethernet utp network. The tia eia 568 a standard which was ratified in 1995 was replaced by the tia eia 568 b standard in 2002 and has been updated since. Early ethernet used various grades of coaxial cable but in 1984 starlan showed the potential of simple unshielded twisted pair this led to the development of 10base t and its successors 100base tx 1000base t and 10gbase t. The following picture shows the structure of the cat5e cable.

Cat5e uses four twisted pairs for transmission in each cable.

For indoor telephone applications utp is often grouped into sets of 25 pairs according to a standard 25 pair color code originally developed by at t corporation a typical subset of these colors white blue blue white white orange orange white shows up in most utp cables.

They can also be known as t 568a and t 568b. The termination of cat5e ethernet cable should use rj45 connectors.
