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.
Ethernet cable 568b.
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.

According to the connection requirement straight through or cross over cable may be required.
Therefore the cable itself will physically perform the crossover function.
This is rectified by correctly pairing the pins.
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.
Avoid swapping two lines between different pairs.
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.
In fact patch cable and crossover cable are two types of ethernet cable and they have the same physical characteristics.
But what on earth is the difference between the patch cable and crossover cable.
Straight through cables are used to connect computers to an ethernet switch.
Crossover cables are occasionally needed for 10base t and 100base t ethernet.
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.
In order to normalize the wire arrangement two standards namely t568a and t568b are used to create these two types of.
The rj45 cable uses only 2 pairs of wires.
