Ethernet cable 568b.
The rj45 cable uses only 2 pairs of wires.
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.
In order to normalize the wire arrangement two standards namely t568a and t568b are used to create these two types of.
Crossover cables are occasionally needed for 10base t and 100base t ethernet.
Before talking about patch cable and crossover cable it s very necessary to learn about the t 568a and t 568b standard.
Straight through cables are used to connect computers to an ethernet switch.
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.
This is rectified by correctly pairing the pins.
Avoid swapping two lines between different pairs.
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.
Therefore the cable itself will physically perform the crossover function.
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.
Orange pins 1 2 and green pins 3 6.
The other two coloreds brown blue pairs of wires are used for another ethernet network application or for phone connections.
But what on earth is the difference between the patch cable and crossover cable.
