Common network cable making connection mode

568A line order from left to right in turn: White green, green, white orange, blue, white blue, orange, white brown, Brown.

568B is: white orange, orange, white green, blue, white blue, green, white brown, Brown.

The crossover line means: One end is a 568A standard, the other end is a 568B standard twisted pair.

Straight line refers to: Both ends are 568A or 568B standard twisted pair.

Use direct connection when the following devices are interconnected:

1. Connect the switch or hub to the router;

2. Computers (including servers and workstations) are connected to the switch or hub.

You use a crossover line when the following devices are interconnected:

1. The switch is connected with the switch through the uplinks port;

2. hub and switch connection;

3. Connection between hub and hub;

4. Two PCs are connected directly;

5. The connection between router interface and other router interface;

6. The ADSL modem of Ethernet interface connects to the network card interface of PC.

How to make Gigabit cable

The form of Gigabit 5 or Super 5 twisted-pair lines is the same as that of the hundred-gigabit cable, which is also divided into two kinds: straight and cross. Straight line cable and we usually use no difference, are one by one corresponding. But the traditional hundred gigabit network only uses 4 cables to transmit, and gigabit network to use 8 to transmit, so the production of gigabit crossover wire is different from the hundred trillion, the production method is as follows: 1 pairs of 3,2 to 6,3 to 1,4 to 7,5 to 8,6 to 2,7 to 4,8 to 5

For example:

One end is: half orange, orange, half green, blue, half blue, green, half brown, Brown;

The other end: Half green, green, half orange, half brown, Brown, orange, blue, half blue
