T568b Straight Through Ethernet Cable

Two different wiring standards exist for wired ethernet.

T568b straight through ethernet cable.

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. T568a a wiring and t568b b wiring. T568a and t568b both provide wiring schemes for terminating network cables to eight position rj45 jacks and plugs. To make a straight through ethernet cable you can use either t568a or t568b.

As long as you use the same standard in both ends of your cable. Note that the only difference between t568a and t568b is that pairs 2 and 3 orange and green are swapped. Straight through cable use one wiring standard. Orange pins 1 2 and green pins 3 6.

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 only difference between t568a and t568b is that pairs 2 and 3 orange and green are swapped. T 568b straight through ethernet cable both the t 568a and the t 568b standard straight through cables are used most often as patch cords for your ethernet connections. Straight through cables are used to connect computers to an ethernet switch.

If you require a cable to connect two ethernet devices directly together without a hub or when you connect two hubs together you will need to use a crossover cable instead. Both ends use t568a wiring standard or both ends use t568b wiring standard. What is crossover cable. Some ethernet interfaces can cross and un cross a cable automatically as needed a handy feature.

In order to normalize the wire arrangement two standards namely t568a and t568b are used to create these two types of cables. A crossover ethernet cable is a type of. A and b wiring offer the same electrical properties and either standard can be used. The rj45 cable uses only 2 pairs of wires.

Two computers via their network interface controllers or two switches to each other by contrast patch cables or straight through cables are used to connect devices of different types such as a computer to a. Generally all fixed wiring should be run as straight through. Both configurations wire the pins straight through i e pins 1 through 8 on one end are connected to pins 1 through 8 on the other end. It is most often used to connect two devices of the same type e g.

The following figure shows a straight through cable of which both ends are wired as the t568b standard. According to the connection requirement straight through or cross over cable may be required. On a straight through cable the wired pins match. The wiring standards t568a and t568b are used to create a cross over cable t568a on one end and t568b on the other end or a straight through cable t568b or t568a on both ends.
