Network cable practices:
I. Connecting a PC to a hub

End A: (Standard 568b): white orange, orange, white green, blue, white blue, green, white Brown, and brown.
End B: (Standard 568b): white orange, orange, white green, blue, white blue, green, white Brown, and brown.

2. Connecting PCs

End A: (568a): white green, green, white orange, blue, white blue, orange, white Brown, and brown;
End B: (Standard 568b): white orange, orange, white green, blue, white blue, green, white Brown, and brown.

3. Hub Connection

End A: (568a): white green, green, white orange, blue, white blue, orange, white Brown, and brown;
End B: (568b): white orange, orange, white green, blue, white blue, green, white Brown, and brown.
Gigabit 5 category or over 5 category (including 6 category) twisted pair wires are in the same form as 10-Gigabit Network cables. They are also divided into two types: pass-through and crossover.
The straight-through network cable is exactly the same as what we usually use.
However, the traditional 10-Gigabit network only uses four cables for transmission, while the 1-gigabit network uses eight cables for transmission. Therefore, the production of a 1-gigabit crossover network cable is different from that of a 10-Gigabit network cable. The method is as follows:
1 to 3, 2 to 6, 3 to 1, 4 to 7, 5 to 8, 6 to 2, 7 to 4, 8 to 5. For example:
End: White orange, orange, white green, blue, white blue, green, white Brown, and brown;

Other end: white green, green, white orange, white brown, brown, orange, blue, white blue;

T568b: Orange, orange, green, blue, blue, green, brown
T568a: green, green, orange, blue, blue, orange, brown, brown
Direct Connection: both ends are made into t568b or t568a. Used to connect different devices (such as NICs to vswitches ).
Crossover line: one end is made into t568b and the other end is made into t568a. Used to connect the same device (such as the network card to the network card ).
There are only four shrapnel in the 10 m Nic, and the other four of the eight wires do not work, so the requirement is low. The two sides can be in the same order, but it is best to follow the standard; there are eight shrapnel in the M Nic, four are used for data transmission, and the other four are used to prevent crosstalk. The cables can be established in strict accordance with the specifications to reduce network faults.

The title part is also copied. Because I do not know which data is transmitted or which is blocked ..
If this is not the case, let's say what it is, even if we throw Chinese cabbage.

Generally, the local area network is 1236, Which is useless. 1-3 is a group, and 2-6 is a group.
