How to replace a chip on an Internet cable. Direct twisted pair connection by color. Crimping patch cord without pliers

Network cable or twisted pair- this is a special wire that consists of four pairs of copper wires twisted together. This number of cores and the design itself help reduce the influence of all kinds of interference. Crimping a network cable is necessary to attach special connectors (connectors) to it for connecting to a computer. With its help they create local network and connect devices to each other.

When crimping, 8P8C connectors with 8 pins are most often used. Most often they are called RJ45. Crimping the cable itself is not difficult, but you need to choose the connector carefully - some of them are used only by professionals. There are two types:

• Unshielded, which are used for UTP wires;
• Shielded - for STP or FTP.

There are also connectors with an insert, but they are intended only for soft stranded wires. If the wire is hard, then using them will be extremely inconvenient.

Inside the connector there are eight recesses designed for wires. Above them are metal contacts. The cord cores must be placed in these recesses, and when the connector is closed, they will connect to the contacts. You need to place the connector with the latch facing you, with the contacts facing up, so that the numbering is correct. In this position, the first recess will be on the right, the eighth on the left. It is recommended to start installation from the first contact.

There are two main distribution schemes: EIA/TIA-568A and EIA/TIA-568B. The veins are arranged differently in them. There are only four pairs of them in the power cord, less often - two. For such wires the circuit will be different.

Crimping options

There are several crimping schemes for twisted pair RJ 45: crossover and straight. Difference in purpose of use:

• Direct is used when the cable will be used for communication network equipment(with a computer or between each other), and connecting client equipment. This method is used most often.
• A crossover is used to connect computers with each other. No other equipment should be used. Less commonly, this method is used to connect devices through up-link ports.

Either method can be used, but both ends must be crimped equally. Usually when direct crimp use a 568V circuit.

IN lately Cables that have only two instead of four twisted pairs are gaining popularity. With their help you can connect only two devices. In case local traffic high, it is not advisable to use this method, because the data transfer speed will decrease from 1 Gbit/s to 100 Mbit/s.

Either orange and green or blue and brown are used. The contacts are connected in the same way as in the case of using all 8 wires.

To make a crossover cable, one end of the cord is crimped according to the 568 V circuit, the other - according to 568 A. All wires must be used. This method gives a relatively low speed.

To provide more high speed use a special scheme: one end of the cable is crimped along color scheme 568V, and the pinout of the network cable is at the other end should be like this:

1. white with green;
2. green;
3. white with orange;
4. white with brown;
5. brown;
6. orange;
7. blue;
8. white with blue.

To create a network of two or more computers without using other equipment (switches, routers, etc.), a different twisted pair pinout is used.

8 wire color scheme allows you to connect two devices by simply inserting the cable into them network ports. Different ends are crimped according to different patterns.

Necessary tool

To crimp RJ-45 twisted pair cables, you need a special tool, it is called crimping pliers. Its other name, which is used by experts, is crimper.

There are two types of crimpers: lever and press. Lever ones (on the left in the picture) are cheaper, but they are more difficult to work with: you need to make physical efforts, but the compression still turns out to be uneven. The design of the latter implies the presence of a comb that moves perpendicular to the connector, installing contacts into it.

To crimp the cable, you must first separate and strip twisted pairs, insert them into the recesses on the RJ-45 and the entire structure into the groove on the crimper. After this, bring his arms all the way down. Then you need to press the connector latch against the body and remove it from the pliers.

There is a method that allows you to crimp a cable without a crimper. To do this, you will need a vice (or other device that will allow you to fix the RJ-45 plug), a screwdriver, and a hammer. You must first insert the wires into the contact, then secure it with a vice at the side parts. Then use the tip of a screwdriver and a hammer to carefully deepen the lamellas, snap the cable clamp - and you're done.

In this method it is important so that the tip tip is no more than 55 mm, otherwise it will crush the insulating sides, because the lamellas in the connectors are 56 mm thick. If this happens, you need to cut off the hanging edges with a sharp knife, otherwise the socket contacts will cling to the edges and there will be no contact.

Use of used connectors

If you need to crimp the cable urgently, but you don’t have a new connector at hand, you can use the old one. To do this, you need to clamp the connector clamp with a vice and carefully pry off the lamellas with an awl, pulling them out 1 mm. Then use a knife to cut the latch on the cable side, remove it and the old twisted pairs. In this case, the cable clamp is removed, and in order to secure a new one, you need to drop silicone or sealant into the resulting space.

Crimping after removing old power cord occurs in the same way as if the connectors were new. If it is necessary to repair damage to the cord, or to lengthen it, you can use twisting or soldering instead of crimping a new cable. Spike is much more reliable.

In this instruction I will show you how to compress the network LAN cable and make an Internet cable with your own hands without tools. Instead of a crimper (special tool for crimping twisted pair cables into RJ-45) we will use a regular screwdriver. And for stripping twisted pair cables, use a knife.

In the article I showed the whole process using a crimper. And he promised to prepare a guide for crimping an Internet cable without crimping pliers. Everything is simple here: if you already have a special tool, then you most likely do not need all these instructions, you are already in the know. And if you are looking on the Internet how to make it yourself network cable, then you most likely do not have a crimper. And you are not going to buy it, for the reason that you simply do not need it. The tool is not cheap, and buying it to crimp two connectors is not best idea. Therefore, everything can be done with a regular screwdriver and knife. Yes, it may turn out a little collective farm and not the first time, but it will work. But on a budget and without outside help.

We will need the following materials and tools:

• The cable itself is twisted pair. I took a small piece, but your cable should be the required length. Buy a little extra.
• RJ-45 connectors. To make one network cable you need two connectors. But be sure to buy more. The connector is disposable. And if something doesn’t work out the first time, you’ll have to go to the store again.
• A screwdriver with which we will crimp the twisted pair into the RJ-45 connector.
• Knife for stripping twisted pair cables.
• And preferably some wire cutters to straighten the wiring. You can also use wire cutters, which are usually found on pliers. If you don’t have wire cutters or pliers, you can cut the cable with scissors or a knife. This is not very easy to do correctly, but in a pinch it is possible.

This is the set I have:

My knife is a little big for this kind of work, but that doesn’t matter. The main thing is that it is spicy :)

As it turned out (I learned about this while writing the article) that there are so-called tool-free connectors. Interesting thing. With their help, you can make an Internet cable even without a screwdriver. All you need is a cable stripper. They look something like this (pictured is a SUPR connector):

How they work: strip the cable and insert it into the connector. On the connector itself there is even a diagram of where to insert which wires. Then we simply snap it on and the cable is crimped. It doesn't seem to be a very popular thing. I don’t even know if you can buy such a connector in a regular store. You need to ask.

Before you start crimping a twisted pair using our screwdriver, you need to decide on the scheme according to which we will make the cable.

LAN network cable crimping diagrams

There are two ways in which you can make an Internet cable. Most likely you need the first method, direct crimping. Let's take a closer look.

There are two crimping methods: T568A and T568B. I did it according to the T568B circuit, which you can see below. It turns out that we crimp both connectors the same way.

I think you have decided on the scheme. You can read more about this in the article:. I will make a simple cable (straight crimp) according to the T568B scheme.

Crimping a twisted pair cable without a tool (crimper)

If you have everything you need, you can start making the cable. I will try to show everything as detailed and step by step as possible.

Insert the wires all the way. They should go all the way in and rest against the front wall of the connector.

The contacts must be pressed in firmly. So that they pierce the cable. The contact itself should not just align with the connector body, but be slightly recessed into the body. The task is not the easiest. When I crimped the cable with a screwdriver, it was difficult to insert into the LAN port of the router (but it was already working), after which I further tightened the contacts with a screwdriver.

After I crimped each pin, I also snapped the cable clamp into place. It is simply pressed inward and the outer insulation is pressed down.

Everything is ready. We do the same on the other side of the cable. I got it like this:

As you can see, the contacts themselves are slightly damaged by the screwdriver. When crimping with a crimper there is no such damage.

I tested the cable by connecting my laptop to the router. The Internet appeared on the laptop, which means that everything worked out and is working. I managed to make a network cable the first time. Even without a special tool, using a regular knife and screwdriver. I hope everything worked out just as well for you.

What to do if the network cable does not work?

It may be like that. But I wouldn’t rush to blame everything on the cable right away. It is quite possible that the problem is with the router, computer, or other device you are connecting. Need to check.

• Connect another device using the manufactured cable. If possible, check the devices by connecting them with a different cable. To make sure that the problem is in the network cable that we just crimped.
• Be sure to carefully check the sequence of wires in the connector according to the diagram.
• If you mix up the sequence of wires, then bite off the connector and redo it.
• If everything is according to the diagram, then take a screwdriver and press the contacts on the connector. It is quite possible that there is no contact.

That's all. Write in the comments about your results, ask questions, and share tips. Good luck everyone!

Good day, dear visitors! I then remembered that I have not yet written about how to crimp a network cable and how to crimp it. I think you know what a network cable is. This is the cable through which you most likely receive the Internet, connect a computer to a router, or two computers directly, simply by connecting the network cable to the network cards of two computers.

And you probably know that the network cable is sold without connectors. Connectors are a thing at the end of a network cable that connects to network card, router, etc. Why is this? Can you imagine what holes would have to be drilled in order to push the connector through :). And so, a network cable is laid and after that RJ-45 connectors are crimped onto it, everything is very convenient and thought out. Well, now we have come to the point that the network cable needs to be crimped, this means that you need to put a connector on the cable and fix it.

I just have a network cable, several RJ-45 connectors, a special tool and a phone with which I will photograph all this, so that my instructions are clear and you quickly learn how to crimp twisted pair cables.

To crimp the network cable we need:

1. Myself network cable, immediately measure out the required amount of cable.
2. Connectors. In theory, you only need two, but I advise you to buy more, just in case :). They are not expensive, and you can buy them at any computer store, just like a cable.
3. Crimping tool. There are several options, ideally you need to buy a special tool, crimper. Like the one I have in the photo above. I bought mine for 75 UAH. (300 rubles). If you don’t have such a thing, you can use a screwdriver, but I don’t recommend it.
4. If you crimp with a screwdriver, you will also need a regular knife to strip the cable.

Well, let's get started.

Crimping the network cable

There is one more nuance; we need to decide which of the two options we will use to crimp the cable.

Direct– such a cable is suitable for connecting a computer to a router, for a regular Internet cable, etc. We can say that this is a standard.

Get to the point.

Take the cable and remove the top insulation. Simply stepping back about two centimeters from the beginning of the cable, we make an incision in the top insulation; in a tool like mine, there is a special hole into which we insert the cable and simply twist the crimper around the cable. Then remove the white insulation by simply pulling it off the cable.

Now we unwind all the wiring so that they are one at a time. We pinch them with our fingers and arrange them in the order we need, depending on which cable you are crimping. See diagrams above.

When all the wires are aligned correctly, you can still trim them a little if they turn out to be very long, and it won’t hurt to align them. This means that when everything is ready, we very carefully and slowly begin to insert these wires into the connector. Make sure that the wires fit into the connector correctly, each into its own hole. Once the cable is inserted into the connector, double-check that the cores are positioned correctly, then insert the connector into the crimper and squeeze the handles.

With the advent of the Internet, the lives of many families have changed. Most of them are connected to the Internet, especially since you don’t need much for this, it’s enough to have personal computer or the most common one mobile phone. In turn, each family member can be connected to a separate line. Local distribution of the Internet resource is carried out wirelessly By special Wi-Fi protocol. And yet, many prefer distribution by wire, as it is much more reliable, simpler and cheaper. In addition, the presence of additional electromagnetic waves negatively affects a person’s well-being.

As a rule, they try to hide all wires in the walls so that they do not interfere. Internet cables are no exception. This is mainly carried out during the period of repair work. For this, there are special sockets called computer or information sockets. Basically, sockets with RJ-45 connectors are used. You can do all the installation processes yourself if you know how to do it, especially since there can be more than two wires and you need to know which contact to connect to which. The procedure is performed not by twisting or soldering, but by crimping, using a special tool for this.

The Internet cable that enters the apartment is called twisted pair and is connected to a plastic connector. This plastic connector is called a connector, designated RJ-45. Professionals call such devices “Jacks”.

Basically, the plastic connector is made of a transparent material through which all the different colored wires are visible. Exactly the same parts are used to connect computers, a modem to a computer, and other computer hardware. In this case, the arrangement of colored wires may not be the usual one. This is the connector that is inserted into the information socket. The most important thing here is to understand the order of all the wires and then the problem with crimping the connector will be solved.

There are two connection schemes: T568A and T568B. We do not practice the first connection option, and the connection is carried out according to scheme “B”. Therefore, you need to familiarize yourself with the arrangement of colors according to this scheme.

Very important point– this is the number of wires in a twisted pair. As a rule, cables with 2 pairs or 4 pairs of wires are used. 2-pair cables are used to transfer data at speeds up to 1 Gb/s, and 4-pair cables are used to transfer data at speeds from 1 to 10 Gb/s. Internet cables are installed in private houses and apartments, where data transfer is carried out at speeds of up to 100 Mb/s. Despite this, there is a steady trend towards increasing the speed of transfer of Internet resources. Therefore, it is better to play it safe and install a 4-pair cable with the future in mind. Moreover, the connectors and sockets are produced for connecting 4-pair twisted pair cables.

When using a 2-pair cable, after laying the first 3 wires according to diagram “B”, the green wire is connected to the sixth contact, skipping two contacts. This can be seen in the corresponding photo.

To crimp the ends on the connector, special pliers are used, which can cost from 6 to 10 dollars, depending on the manufacturer. When using such a tool, high-quality contacts are obtained, although this can be done using wire cutters and a screwdriver.

First, you need to remove the protective insulation from the cable, at a distance of 7-8 cm from the end of the cable. The cable contains four pairs of wires of different colors, twisted in pairs. There are cables with a thin shielding braid. It won't be needed, so you can simply bend it to the side. All pairs are untwisted, and the wires are aligned, spread apart and laid out according to pattern “B”.

The separated wires are clamped between the thumb and forefinger. At the same time, you need to make sure that the wires are straight and tightly pressed to one another. If the wires are of different lengths, they can be aligned with wire cutters, leaving a total of 10-12 mm in length. If you take the connector and try it on, the insulation of the wires should start slightly above the latch.

This can also be seen in the photo. After this, the prepared wires are inserted into the connector.

It is very important that each wire falls into a special path, and each wire must rest against the edge of the connector. Holding the cable in this position, it is inserted into the pliers. Crimp the cable with a smooth, careful movement until the handles of the pliers come together. If all prepared operations are performed correctly, then there should be no problems. If you feel that additional force is needed, then it is advisable to pause the crimping process and check everything again. The main thing is that the connector is in the correct position. After checking and adjusting, crimping continues.

During the crimping process, the pliers push the conductors towards the microknives, which push the insulation and establish contact with the conductor.

The result is reliable connection with excellent contact. If it doesn’t work the first time, the crimping process must be repeated. To do this, the wires with the “jack” are cut off, stripped, a new “jack” is taken and the process is repeated. The main thing is to stock up on “jacks”, because it’s unlikely to succeed the first time.

Video tutorial: crimping an RJ-45 connector

Thanks to the advent of the Internet, many problems are solved quite quickly, especially after watching videos. Therefore, before proceeding directly to crimping the wires, it is advisable to review the video, and very carefully. It shows how to properly handle ticks and how you can do without them. And yet, it’s better to play it safe and use a tool for better work.

How to connect an internet cable to a power outlet

To begin with, it should be noted that Internet sockets, like electrical sockets, there are two types: for external installation and for internal installation.

It should be noted that all sockets are collapsible and consist of three parts: half of the socket body is used for fastening, the inside of the socket is intended for connecting wires, and the second part of the body serves as a protective element. There are both single and double Internet sockets.

Computer outlets may vary in appearance, but their operating principle is the same. All of them are equipped with microknife contacts. As a rule, they are designed to cut through the insulation of conductors, after which they are installed reliable contact, since the process is carried out under a certain gain.

Connecting a computer wall socket

Almost all manufacturers of computer sockets place a connection diagram inside, indicating the order in which the wires are placed, based on their colors. As a rule, both scheme “A” and scheme “B” are indicated. Scheme “A” should not be taken into account, but focus on scheme “B”.

First of all, proceed to install the case on the wall, positioning it so that the cable inlet faces up and the computer connector faces down. Although this installation option can be changed, depending on specific conditions, the outlet can be installed horizontally.

As you can see, connecting an Internet outlet is not a complicated operation and anyone can handle it. This may only take a few minutes. IN in this case Once is enough, although it may not work the first time, especially if you do not have the skills to handle wires.

In order not to suffer too much, it is better to watch the corresponding video, which shows and tells how to connect a computer outlet with 4 wires and with 8 wires.

Despite the different number of wires, the connection technology is the same.

Connecting an internal Internet outlet

The main task of the connection is to be able to correctly disassemble the Internet outlet, since each manufacturer solves this problem in its own way.

The most important thing is to disassemble it so that there is free access to the contacts with the microknives. It is in this part that the connection is made, after which the housing cover with the contacts is closed. Each model of such an outlet has its own method of assembly and disassembly.

If we take, for example, a Legrand computer socket, then in order to get to the place where the wires of the Legrand Valena RJ-45 socket are connected, you first need to remove the front cover. Inside the case you can see a white plastic panel with an impeller, where an arrow is drawn (see photo).

The handle on the panel is turned in the direction of the arrow, after which the front panel is removed. On the surface of the panel there is a metal plate with a pattern, from which you can determine which contacts and which wire should be connected. The color marking of twisted pairs is also indicated here. Before starting the connection, wires prepared for the connection process are threaded into the hole located on the plate.

To make it more clear, it is better to watch the prepared video.

You can also find a socket for connecting the Internet from Lezard. Here the design is completely different. The front panel is designed with screws, so to remove it, just unscrew these screws. As for its insides, everything here is secured with latches. To remove the insides from the body, you need to pick up a regular, small screwdriver and squeeze the clamps.

To get to the contact group and remove it from the housing, you need to press the latch, which can be found on top. As a result of such actions, you may end up with a box in your hands, from which you will have to remove the cover to get to the contacts. To remove the cover, just pry it with a thin object side lobes. You still have to put in some effort, since the latch is quite elastic. At the same time, you need to remember that you are holding plastic in your hands and if you do not do everything carefully, you can break it.

For greater clarity, we suggest you watch the video tutorial.

In conclusion, it is worth noting that the presence of a corresponding video on the Internet simplifies the process of mastering various actions or carrying out work related to connecting computer sockets. Despite the fact that each outlet model is designed differently, the connection process is the same for all. The most important thing is to master the connection process yourself, associated with certain features. It would seem that it would be easier if the connection was made using twisting or soldering, which would be accessible to almost everyone. But at the same time, it would not be possible to ensure the compactness and accuracy of the connection itself. But such connections have their advantages: you wouldn’t have to stock up on jacks. Although, on the other hand, this connection method is more designed for professionalism, simplicity and speed, especially if you use a special tool.

And, nevertheless, if you have at least some skills in working with electrical wires, then such a connection does not contain any difficulties. Without inviting any specialists, you can actually install a computer network in your apartment or private house. Moreover, such specialists will charge a considerable amount for this.

Today, many people have a computer in their apartment and Internet access. Often there is a need to connect a computer to the Internet using a cable or extending the wire when moving the user device to another location. You may also want to create home network from several computers. All these issues can be resolved by creating an Internet network from a special cable.

Basic Concepts

A special type of cable intended for the manufacture of computer and telecommunication networks is called “twisted pair”. It consists of several pairs of copper conductors in insulation, twisted together with a certain number of turns per unit length. The most common is 8-core twisted pair. All conductors are placed in a common polyvinyl chloride (PVC) sheath.

A slight twisting or twisting is done in order to neutralize interference from electromagnetic radiation generated by the conductors themselves and third party sources. Because when the veins are close together, the result they create electromagnetic radiation cancel each other without creating signal loss. In addition, external interference is caught by two twisted conductors in the same way, and therefore is easily recognized by the receiving device and cut off. The end result is quality digital signal with minimal losses.

Modern computer networks are connected using cable of the fifth category and higher. The most common modification of cables No. 5 and No. 5e today is capable of operating at frequencies of more than 100 and 125 MHz, transmitting up to 1000 Mb/s, with a core cross-section of 0.5 mm 2. The sixth and seventh categories of cables are used for high speed internet, have throughput up to 10 and up to 100 Gb/s, respectively, and with thicker cores.

Types of twisted pair

1. UTP - twisted pairs are not shielded, there is no external shield. The most common type for apartments computer networks, when there are no large interference and distances.
2. FTP - twisted pairs are not shielded, but are external screen from foil. It is used in small offices where it is necessary to transmit data over distances of up to 100 m without loss of speed, and where interference occurs.
3. STP - each twisted pair is braided with wire protective screen, there is an external screen. Used in medium-sized offices and establishments where there may be interference. Allows you to maintain signal quality when transmitting to long distances, but not higher than 100 m.
4. SF/UTP - twisted pairs are not shielded, but there is an outer copper braid and foil film that make up a double shield. They are used in enterprises to maintain signal quality over long distances and to protect against interference.
5. S/FTP - each twisted pair is shielded with foil, there is an external shield in the form of a copper braid. It is used in enterprises with large interference and where it is necessary to maintain the speed of information transmission over a long distance.

The cable insulation color gray is the most widely used. The color is red or orange - it means the insulation is made of non-flammable material.

Two ways to crimp twisted pair cables

The Rj-45 computer cable is connected to the device using an 8P8C connector (an abbreviation of the English words 8 positions, 8 contacts). This connector is installed on the cable by crimping a twisted pair of 8 cores according to the color scheme, depending on the telecommunication standards.

Standard 568-A is obsolete and 568-B is most often used.

Following the diagram, the cores for the 568-A system are laid out as follows:

1. White-emerald.
2. Emerald.
3. White and red.
4. Blue.
5. White and blue.
6. Ginger.
7. White chocolate
8. Chocolate

The order of colors when crimping twisted pair cables according to the 568-B standard is as follows:

1. White and red.
2. Ginger.
3. White-emerald.
4. Blue.
5. White and blue.
6. Emerald.
7. White chocolate.
8. Chocolate.

The connector has eight grooves into which 8 twisted pair wires are laid according to the color scheme. The pinout is shown above.

Network cables are needed to connect computers and various combinations. For example, connect a router to the network, a computer to the router, two computers together, a splitter, a TV to the router. There are two options for making network cables.

Direct twisted pair connection by color

The first way is direct. The pinout of twisted pair 8 wires can be done both according to the 568 A standard (when one and the other ends of the wire are crimped according to the 568 A type) and according to the 568 V standard (when one and the other ends of the wire are crimped according to the 568 V type).

In our country, the 568 V method is common, and in the USA and Europe the 568 A type is most often used. The only difference between these two methods is the swapped white-green cores with white-orange and green with orange. Used to connect various user devices (computer, TV, laptop) to network equipment (switch, router, hub, router, patch cords, extender), and is also used to connect network devices among themselves. The information transfer speed with this scheme is 1 Gbit/s.

Direct twisted pair connection 100 Mb/s

In some cases, when high Internet speed is not required and large volumes of traffic are not provided, you can use a connection based on the colors of a twisted pair of 4 cores: white-red, red, white-emerald, emerald. This method saves wire consumption, but it must be taken into account that the highest information transfer speed drops 10 times and amounts to 100 Mb/s.

Twisted pair cross connection

The second method is cross or crossover. Crimping a twisted pair of 8 cores (color scheme) is shown below; it is used to connect two computers into a home network without any network equipment or two client devices of the same type (computer, TV, laptop).

To make a crossover cable, you need to crimp one end of the wire according to the 568 A standard, and the other according to the 568 V standard. In this case, the wires are swapped: white-red with white-emerald, red with emerald. In this case, the information transfer speed will be only 100 Mbit/s. The Gigabit Crossover scheme involves exchanging places of all eight cores: white-red with white-emerald, red with emerald, blue with white-chocolate and white-blue with chocolate. This 8-wire twisted pair pinout color scheme is designed for high-speed 1000Base-T and 1000Base-TX networks when the information transfer rate is 1 Gbps.

To summarize, we can understand that if you need to connect a computer to the Internet, both ends of the cable should be crimped using the 568 V type. If you want to connect two computers to each other, then you should use the Gigabit Crossover circuit, where the first end of the wire is crimped using the 568 A type, and the other by swapping all eight wires.

How to crimp a network cable?

Now that you know how to correctly connect a twisted pair cable by color, you can begin crimping. How to do this is described below.

Tools and materials

Sequence of actions

Using two knives on the crimper, you can cut the cable to the desired length. Then remove 2 cm of outer insulation from both ends of the cable using a knife and the notch on the crimper, located near the handles of the tool. This can also be done with a stripper or a sharp knife, but only carefully so as not to damage the core insulation.

Unwind the twisted pairs to make 8 separate wires. Lay out 8 wires in a row, according to the color scheme of the twisted pair pinout.

It is necessary that the ends of the cores are all on the same line, one is not longer than the other. The quality of the crimp depends on this. If one of the strands is longer, it should be cut to the level of the others. The connector is turned over with the latch down, then all the wires are inserted into the connector along the grooves until they stop, observing the pinout. The outer insulation of the cable should end up in the connector body; if this does not happen, you need to cut the ends shorter.

Insert the connector with the cable into the crimper socket marked 8P. Squeeze the handles firmly but smoothly until you hear a click. If you have a tool at hand, this procedure is quite simple, but if you don’t have pliers, you can get by with a flat-head screwdriver. To do this, you need to place the tip of a screwdriver on the connector contact and press until it cuts through the core insulation with its teeth. Do this for each of the eight contacts. Then you should also push through the central part of the connector body - the recess on the connector near the cable entrance, for fixation. If it doesn’t work the first time, you can cut off the failed connector and do it again.

Check the quality of work using a multimeter. To do this, you need to set the device to “resistance” mode. To check the device, connect the two probes to each other, it should show a resistance of 0 - this means there is contact. Then place one probe on the contact on one edge of the cable, and the other probe on the corresponding color contact on the other edge.
