Network Cable Wiring B

B maintains backwards compatibility with only one pair usoc wiring but is also compatible with 258a wiring.

Network cable wiring b.

A maintains backwards compatibility with one and two pair versions of usoc wiring. 8 position refers to the fact that rj45 data transmission requires 8 conductors which are provided by the 4 twisted wire pairs found in the copper based network. The only difference between t568a and t568b is that pairs 2 and 3 orange and green are swapped. Based on tia eia 568 b 1 2001 the t568a and t568b wiring schemes define the pinout or order of connections for wires in eight pin modular connector plugs and jacks.

The main similarity between t568a and t568b is that they both provide wiring schemes for terminating twisted pair copper network cable to 8 position rj45 jacks and connectors.

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. You re basically choosing between better usoc compatibility or better 258a compatibility and you probably don t need either. A straight through ethernet cable which is used to connect to a hub or switch and a crossover ethernet cable used to operate in a peer to peer fashion without a hub switch. This is the option shown in most home wiring videos on youtube.

Generally all fixed wiring should be run as straight through. This results in a potentially slower network but it is the option chosen when cable routing isn t inside the wall. Rj45 pinout diagram shows wiring for standard t568b t568a and crossover cable. Both standards define the t 568a and t 568b pin outs for using unshielded twisted pair cable and rj 45 connectors for ethernet connectivity.

The other option is to use several switches perhaps one per floor and wire those switches back to a central location.
