What is the use of each line of the crystal head

In fact, four of the 8 sheets are used for the Internet. They are: orange-white, orange, green-white, green.

The other four are: blue, blue-white, brown-white, brown-white. These four can be connected.

If your network crystal head does not connect these four lines, it can also be used. The order of the network crystal head is: orange-white, orange, green-white, blue, blue-white, green, brown-white, brown-white, brown, so the network uses line 1236.

You are talking about twisted pairs, a wire can be divided into four pairs (eight), the colors are: orange white, orange green white, green blue and white, blue brown white, brown orange green blue brown brown four colors should be solid colors, and then orange white, green and white, blue and white, brown and white four are twisted into a strand with the corresponding solid color of the line, so that it is four strands Like you said orange and white and green white, blue and white, brown and white can not distinguish the color, that is because the quality of the twisted pair you buy is not good, *** some twisted pair orange and white and green and white, blue and white, brown and white four lines have color stripes, Even if the thread is very short, it can be distinguished, but you don't, it's all white In this case, you should peel the thread a little longer, and gently cut it with a knife after the length is appropriate, and then gently filter the thread, don't rush to disrupt the thread sequence, you should see two strands after dialing it, a total of four strands of four colors of the line, and then carefully move each strand of wire to four directions, so that the crystal head is easy to find the corresponding color, I have encountered such a situation before.

Hello Kiss is happy to answer this question for you. The order of the crystal head connector line is as follows: 1. The order of the ADSL broadband crystal head is:

The first is to connect the orange-white network cable, then to the orange one, then to the green-white and blue, and then to the blue-white, green, brown-white and brown to the blind hole. 2. The crossing line is: just one end is connected to the green and white network cable, then connected to green and orange and white, then connected to blue, blue and white and orange, and finally connected to brown and brown, and the other end is to connect orange and white first, then orange, green and white and blue, followed by blue and white and green, and finally brown and brown.

The connection method of the network cable crystal head is as follows:1. ADSL broadband crystal head connection method.

Orange White Orange Green White Blue Blue Blue White Green Brown White Brown.

2. Cross-wire connection method (computer to computer burning or router to router) at any end: green-white, green, orange-white, blue-white, orange-brown, white-brown.

The other end: orange white orange green-white blue-white blue-white green-brown white-brown.

3. Direct connection method (router to computer).

Router: orange-white, orange, green-white, blue-white, blue-white, green, brown, white, brown.

Note: The direct connection method can also be used at both ends: "green-white, green-orange-white, blue-blue, blue-white, orange-brown, white-brown". Pi Ju Ye.

Precautions for the color order of the crystal head of the network cable1. If the standard connection method is adopted, the network cable can normally transmit a distance of 100 meters, and the specific network cable transmission distance is also related to the material of the network cable. Generally speaking, the transmission distance of iron and aluminum network cable is about 60-70 meters, the transmission distance of all copper network cable is about 80-90 meters, and the transmission distance of copper clad silver network cable is about 180 meters.

2. Therefore, in order to maintain the normality of the transmission signal of the network cable, it must be connected according to the line sequence of 568b and 568a.

Summary. Hello, at present, the 568b crystal head connection method is used, and the line sequence is white orange, orange, white green, blue, white blue, green, white brown, brown.

Hello, at present, the 568b crystal head connection method is used, and the line sequence is white orange, orange, white green, blue, white blue, green, white brown, brown.

The connection of the network cable crystal head is not complicated, and there are two common methods: parallel wire connection and cross wire connection. 1.

Parallel wire connection method: Use professional tools to cut one end of the network cable neatly, hail and then put the neatly cut network cable into the clamp of the stripping line, remove the outer coat of the head, it should be noted that the network cable can not be bent, after removing the outer coat of the network cable, you can see 4 pairs of 8 core wires, each pair of colors are different. First arrange the 4 pairs of cores side by side, then separate them, use the 568b sorting method, insert them into the crystal head of the network cable, confirm that all the cores are inserted into the bottom, and use the network cable pliers to press the crystal head tightly to ensure that the network cable can fit tightly with the crystal head. 2.

The biggest difference between the cross-wire connection method and the parallel wire connection method is the arrangement of the core wire, and the connection method of the cross wire, both ends of the network cable need to be connected to the crystal head. Therefore, when using this kind of square vertical connection network cable crystal head, it must be noted that one end adopts the 568A core arrangement standard, and the other end adopts the 568B core arrangement standard. After the crystal head is connected at both ends of the network cable, you need to do a test to ensure that the network cable crystal head has been successfully connected and there is no problem of poor contact.

568b line sequence connection nucleus: orange-white orange green-white blue blue-white green brown-white destruction of brown 568a line sequence connection: green-white green orange-white blue blue-white orange stove blind brown-white brown.

The corresponding crystal head connection diagram is as above, I hope it can help you!

There are generally two international standards for the sequence of crystal head connector lines, T586A standard and T586B standard, T586A standard line sequence: white-green-white-orange-blue-white-blue-orange-white-brown-brown; T586B standard line sequence: white-orange-white-green-blue-white-blue-green-white-brown-brown.

Usually, there are 4 pairs of twisted pair cables in the Nianyou network cable we use, a total of 8 lines, for the convenience of Weiyu Sakura, 8 kinds are used to distinguish, among them, there are 4 lines of different colors of solid color lines, and 4 lines are white and these four colors of the two-color line, 8 lines of color is white green, green, white blue, blue, white orange, orange, white brown, brown.

568A standard sorting of network cable wiring: white-green-white-orange-blue-white-blue-orange-white-brown-brown; T586B standard line sequence: white-orange-white-green-blue-white-blue-green-white-brown-brown.

Note: Before wiring, you need to prepare the relevant tools, and the tools that need to be prepared are mainly network cables, network cable pliers, crystal heads, and side line instruments. Once you've got your tools ready, you can place them in order.

At the same time, when placed, it needs to be arranged according to the color, and placed from left to right.

Precautions for the wiring of the crystal head of the network cable

1. The transmission rate is different for different types of network cables. If it is a Category 8 network cable, then the transmission rate can reach 40Gbps; Although the transmission distance is relatively shorter than other network cables, the speed is far higher than that of other categories.

2. If the two parties of the connection are not equal, use a parallel (straight-through) line, such as a computer connected to a router or switch.

3. If the two connected devices are equal, use a crossed wire, such as a computer connecting to a computer.

4. It's okay to connect all of them, because the general network cable is only used, and the others can be used even if they are not connected.
