8 lines in a network cable which 4 is the transmission of data, which four is interference-proof _ Hardware Maintenance

Network Cable Procedure section:
One, PC even hub

A-end: (Standard 568B): White orange, orange, white green, blue, white blue, green, white brown, Brown.
B-end: (Standard 568B): White orange, orange, white green, blue, white blue, green, white brown, Brown.

Second, PC connected PC

A-end: (568A): White green, green, white orange, blue, white blue, orange, white brown, Brown;
B-end: (Standard 568B): White orange, orange, white green, blue, white blue, green, white brown, Brown.

Third, hub even hub

A-end: (568A): White green, green, white orange, blue, white blue, orange, white brown, Brown;
B-end: (568B): white orange, orange, white-green, blue, white-blue, green, white-brown, brown.
Gigabit 5 or Super 5 categories (including 6 types of lines) twisted pair of the form of the same as the hundred-gigabit cable, but also divided into straight and cross two kinds.
Straight line cable and we usually use no difference, are one by one corresponding.
But the traditional hundred gigabit network only use 4 cable to transmit, and gigabit network to use 8 to transmit, so Gigabit crossover cable production and hundred trillion different, the production method is as follows:
1 to the 3,2 to the 6,3 to the 1,4 to the 7,5 to 8,6 to 2,7 to the 4,8 to 5. For example:
One end is: white orange, orange, white green, blue, white blue, green, white brown, Brown;

The other end: White green, green, white orange, white brown, brown, orange, blue, white blue;

T568B: Orange white, orange, green white, blue, blue white, green, brown white, brown
T568A: Green white, green, orange white, blue, blue white, orange, brown white, brown
Direct connection: Both ends are made of t568b or t568a. For different devices to connect (such as NIC to switch).
Cross line: One end made of t568b end made of t568a. Used for homogeneous devices, such as network cards to network adapters.
There are only four shrapnel in the 10M network card, 8 lines of another four do not function so low requirements, the same order on both sides of the line, but it is best to do according to the specification; 100M network card has 8 shrapnel, four for data transmission, another four for crosstalk prevention, strictly according to the specification line can reduce network failure.

The explanation of the title part is also copy. Because I don't know exactly which one to pass the data, which shielding.
If the wrong, everyone in spite of throwing cabbage, throw out the cabbage said the specific is what kind of.

General LAN is 1236, other useless. 1-3 is a group, and 2-6 is a group.
