Rj45 conductor data cable contains 4 pairs of wires.
Network cable wiring 568b.
In order to normalize the wire arrangement two standards namely t568a and t568b are used to create these two types of cables.
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.
T568a and t568b are the two wiring standards for rj45 connector data cable.
Data cabling it can be confusing sometimes.
This is rectified by correctly pairing the pins.
Wiring the ends of the same cable according to different configurations 568a on one end and 568b on the other will create a crossover cable.
Therefore the cable itself will physically perform the crossover function.
Each one consists of solid colored wire and a strip of the same color.
According to the connection requirement straight through or cross over cable may be required.
If you are just getting started on your network or if you need to rewire some things trying to determine what standard you should use or what type of cable to purchase can be a daunting.
T568a was specified by tia eia 568 a wiring standards in 1995.
A crossover cable can be easily created by using the 568a scheme at one end and the 568b scheme at the other end as shown in the 568a 568b illustration.
Crossover cables are occasionally needed for 10base t and 100base t ethernet.

T568a and t568b both provide wiring schemes for terminating network cables to eight position rj45 jacks and plugs.
There are two wiring standards for rj45 ethernet cable wiring.
