What is the order of network cable connection, and what is the order of network cable connection

Connection of normal 100m network conditions:

The standard connection method is one-to-one correspondence: (orange and white) (orange) (green and white) (blue) (blue and white) (green) (brown and white) (brown), that is, the two ends of the network cable are arranged in the same way according to the serial number. (It's okay to arrange the colors at both ends, but the network doesn't work very well.) ）

In fact, in the 100m network, there are only four wires, that is to say, you can also use one network cable to connect two workstations, and the connection becomes like this, make sure that it is the following color.

Group 1: (orange-white), orange), green-white), green).

The second group: (blue), blue-white), brown-white), brown-white).

That is to say, the blue, blue-white, brown-white, brown-white, and brown of the network cable are treated as orange-white, orange, green-white, and green.

Now that many families already have two computers, can they use the most cost-effective way to connect to the Internet? Wouldn't it be nice to play an online game like this!? So:

One end is: orange-white), orange), green-white), green).

One end is: green-white), green), orange-white), orange).

The first group is the same at both ends: (orange-white), orange), green-white), green);

The second group is like this at one end: (blue), blue-white), brown-white), brown-white), and the other end: brown-white), brown), blue), blue-white).

In this way, this network cable can be used to connect to both ordinary networks and dual-machine pairing. Ideal for bringing laptops.

Users who go out, of course, if they bring an adapter, there will be no "net" disadvantage......

1000m network situation approach:

You must have a kilomb switch and a kilomb network card. Both ends of the 1,000m network cable are safe.

586b is as follows:

Ethernet cable, crystal head.

The tools needed for connection are roughly: network cable signing, network cable, and line tester (optional).

Detailed interpretation of the connection and sequencing of the joints of commonly used network cables.

Generally, T568B is used to make crystal heads. In use, the T568A T568B can only be distinguished in the wiring color. Optical fiber and cable and other related things, it is best to use high quality, so that our communication transmission can be stable, we consider comprehensively, with Phoenix.

The T568A is arranged in the following order: green-white, green, orange-white, blue, blue-white, orange, brown-white, and brown.

The T568B is arranged in the following order: orange-white, orange, green-white, blue-blue-white, green, brown-white, and brown.

Using a thin coaxial cable for a network connection is relatively simple, as long as each computer or network device is connected in series, but it is more cumbersome to maintain, and if something goes down, the entire network can be paralyzed. If you add or remove a computer from the network, you must stop working on the network until the computer is added or removed before you can continue to use it. At the same time, this approach must be done in a bus-type topology, which is rarely used today.

The order of network cable connectors** is as follows:

568A Standard:

Green-white-1, green-2, orange-white-3, blue-4, blue-white-5, orange-6, brown-white-7, brown-8.

568b Standard:

Orange-white-1, orange-2, green-white-3, blue-4, blue-white-5, green-6, brown-white-7, brown-8.

The line is a winding pair, the wire is a winding pair, the wire is a winding pair, and the four wires in the twisted pair 4 5 and 7 8 are not defined, so these four wires should not be connected wrong. This is only suitable for household connections within 100 megabits, and 8 wires above gigabit require higher drafts.

First, use crimping pliers to peel off about 3 cm of the outer skin of the network cable, and then arrange the 8 wires in order. After arranging the order, cut off the excess part of the grip and leave more than one centimeter. Then insert the wire into the crystal head, which has the copper side facing up.

Finally, press it with crimping pliers and you're done.

After connecting it, you can use a network tester to test it. The two ends of the crystal head are plugged into the tester, turn on the test switch, the indicators on both sides begin to light up synchronously, if the order of 1 to 8 is lit, the wiring is correct, if you skip a certain number, the corresponding wiring is wrong or the wire is not pressed.

The tester is a digital multimeter key disturbance "semiconductor buzzer gear" and another network cable socket! It's so easy! Just short-circuit all the crystal head sockets in one step, link a special sequence "test seat", and slide the other end with a digital meter, diode, buzzer, and gear to touch each pin, whether there is a buzzer sound!

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

The order from left to right is: white-green, green, white-orange, blue, white-blue, orange, white-brown, brown.

568A and 568B refer to the two colors** used for 8-pin wiring (most commonly RJ45 plugs) module jack plugs. According to the international standard, there are four line sequences: T568A, T568B, USOC (8), USOC (6).

The first two are commonly used.

T568A: Green-White, Green, Orange-White, Blue, Blue-White, Orange, Brown-White, Brown T568B: Orange-White, Orange, Green-White, Blue, Blue-White, Green, Brown-White, Brown-White, Brown Due to backward compatibility issues, the T568B wiring diagram is considered the preferred wiring diagram.

The T568A wiring diagram was marked as optional, but it is still widely used. In simple terms, this specification defines the wiring diagram for the receptacle plug for structured wiring.

Pay attention to the order of the crystal head of the network cable, don't connect the 8 wires randomly, connect the right one to make your network speed long and long.

Two multimeters measure AC current in two different ways, which is more accurate?

Tool materials required for the production of network cables: network cable pliers, wire strippers (can be submerged), network cables, crystal head network cables: white orange, orange, white green, blue, white blue, green, white brown, brown order arrangement Note:

The order of the copper wire of the network cable, the contact piece of the crystal head is upward, and whether the mesh wire is full. The network cable used should correspond to the corresponding crystal head.

Standard 568A: 1 Green White, 2 Green, 3 Orange White, 4 Blue, 5 Blue White, 6 Orange, 7 Brown White, 8 Brown.

Standard 586B: 1 Orange White, 2 Orange, 3 Green White, 4 Blue, 5 Blue White, 6 Green, 7 Brown White, 8 Brown.

There are two common methods of crystal heads, one is 568a, one is 568b, and the crystal head of the same equipment is composed of two crystal heads, one 568a and one 568b. The different devices consist of one or two 568A or 568B heads.

Here are two ways to wire the crystal head:

568a: green-white, green, orange-white, blue, blue-white, orange, brown-white, brown-white, brown568b: orange-white, orange, green-white, blue, blue-white, green, brown-white, brown-white.

The specific steps of the network cable crystal head connection sequence are as follows:Tools: Ethernet cable, crystal head, pliers.

1. First of all, cut off the outer skin of the network cable, which is generally controlled at about 3cm.

2. Untie and sort the network cables, the order is white orange, orange, white green, blue, white blue, green, white brown, brown.

3. Then sort out the network cable and cut it neatly with network cable pliers.

4. Make the copper piece of the crystal head face you, and pass the network cable through the crystal head.

5. Finally, use the network cable pliers to press the crystal head.

PrecautionsIf the two parties of the connection are not in equal status, use a parallel (pass-through) line, such as a computer to a router or switch, or a crossover line if the two devices are connected, such as a computer to a computer. It's okay to connect them all, because the general network cable is only used for others, even if it's not connected, it can be used.

The wiring sequence of the T568B wiring method is orange-white, orange, green-white, blue-blue, green-brown-white, brown-white, and brown from left to right.

The wiring sequence of the T568A wiring method is green-white, green, orange-white, blue, blue-white, orange-brown-white, brown-white, and brown from left to right.

The network cables do not have to be connected in order, as long as the order of the nuclear lease connection at both ends is the same. However, in order to standardize management and prevent interference, some wiring standards for network cables have been formulated, as follows:

1. The wiring sequence of standard 568A is: 1 green white, 2 green, 3 orange white, 4 blue, 5 blue and white, 6 orange, 7 brown and white, 8 brown.

2. The wiring sequence of standard 586B is: 1 orange white, 2 orange, 3 green white, 4 blue, 5 blue and white, 6 green, 7 brown and white, 8 brown.

The disadvantages of not wiring according to the standard and the standard change of the omen.

Not in accordance with the standard wiring, this dismantling to ensure that the line sequence at both ends is consistent, the network cable obtained in this way is only suitable for short-distance use, and the longer distance with this kind of network cable will have a serious problem of signal interference attenuation, and even lead to network failure, network speed card slow situation.

The international wiring standards are T586A and T586B two standards, as long as the 1236 position is connected according to the standard, the rest is arbitrary, because only these four Gigabit network cables work. Gigabit network cables need to be connected in accordance with the standard line sequence. The winding density and winding direction of the twisted pair of network cables are strictly regulated, and the higher the winding density of the network cable, the higher the transmission rate of the corresponding network cable.

A network cable is one of the tools to connect to the Internet, without which the network speed will be greatly slowed down. Common network cables generally include twisted pair, fiber optic and coaxial cables.

Classification of network cable wiring methods

The common wiring methods of network cables are divided into: T568B and the wiring sequence is: white orange, orange, white green, blue, white blue, green, white brown, brown. The wiring sequence of the T568A is: white-green, green, white-orange, blue, white-blue, orange, white-brown, orange-brown.

How to connect the network cable

1. PC with HUB, A-side: (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.

2. PC with 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.

3. HUB with 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 Category 5 or Category 5 (including Category 6 cable) twisted pair cable is the same as the form of 100 Gigabit network cable, and is also divided into two types: pass-through and crossover. There is no difference between the pass-through network cable and the one we usually use, and it is all one-to-one correspondence. However, the traditional 100 Gigabit network only uses 4 cables to transmit, while the Gigabit network uses 8 cables to transmit, so the production of Gigabit crossover network cable is different from 100 Gigabit, and the production 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, 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.

There are two types of wiring Sun Yansui of the crystal head: T568A and T568B, and most of them are T568B.

Peel off the outer skin of one end of the network cable to about three centimeters, and be careful not to cut the copper wire inside when peeling off the outer skin, and then you will see the eight copper wires that are wound after peeling off, and then proceed to the next step.

Arrange all the lines according to the order, the line order of T568 is generally white orange, orange, white green, blue, white blue, green, white brown, brown must not be misremembered when arranged, after the line is straightened, there can be no bends.

Precautions for network cable connection

1. When we peel the network line, we must move slowly, and we can't use too much force, otherwise we will tear off the jujube line inside. When checking the wiring, the face of the line and the bayonet must be the same, and the color of the bayonet and the line must not be confused, otherwise the network connection will not be possible.

Especially for which network cables have four white or orange, green, blue, and brown to be wound, you should pay more attention to the two wires in each group before disassembling the other wires, otherwise it is easy to mess up.

2. Don't be too anxious when crimping the line, it is best to separate and strip all the network cables, and then use the wire pliers to press the line in order.
