How to crimp an internet cable without crimping pliers. How to crimp an Internet cable "twisted pair" with and without clamps

With the advent of the Internet, the lives of many families have changed. Most of them are connected to the Internet, especially since this does not require much, it is enough to have a personal computer or the most ordinary mobile phone. In turn, each family member can be connected to a separate line. Local distribution of the Internet resource is carried out wirelessly using a special Wi-Fi protocol. And yet, many people prefer wire distribution, 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 the wires in the walls so that they do not interfere. Internet wires 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. Mostly sockets with RJ-45 connectors are used. All the processes for installing it can be done by 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. The procedure is performed not by twisting or soldering, but by crimping, using a special tool for this.

The Internet cable that goes into the apartment is called a twisted pair cable and is connected to a plastic connector. A similar plastic connector is called a connector under the designation RJ-45. Such devices are called "Jacks" by professionals.

Basically, the plastic connector is made of a transparent material through which all the colored wires are visible. Exactly the same details are used to interconnect computers, a modem with a computer and other computer hardware. In this case, an unusual arrangement of colored wires is possible. It is such a connector that is inserted into the information outlet. The most important thing here is to figure out the order of the arrangement 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, but the connection is carried out according to the "B" scheme. Therefore, you need to familiarize yourself with the arrangement of colors, according to this scheme.

A very important point is the number of wires in the twisted pair. As a rule, cables with 2-pair or 4-pair number 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 wires are brought into private houses and apartments, where data transfer is carried out at a speed of up to 100 Mb / s. Despite this, there is a steady trend towards an increase in the transmission speed of Internet resources. Therefore, it is better to play it safe and install a 4-pair cable for the future. Moreover, connectors and sockets are available for connecting a 4-pair twisted pair.

When using a 2-pair cable, after laying the first 3 wires according to the scheme "B", the green wire is connected to the sixth contact, missing 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, quality contacts are obtained, although this can be done with pliers 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 where there is a thin shielding braid. You won't need it, so you can just fold it to the side. All pairs are untwisted, and the wires are aligned, spread apart and laid out according to the "B" scheme.

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

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

It is very important that each wire falls into a special path, while each wire must rest against the edge of the connector. Holding the cable in this position, insert it into the pliers. Crimp the cable in a gentle, gentle motion until the handles of the pliers come together. If all the prepared operations are performed correctly, then there should be no problems. If you feel that additional effort 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, the crimp continues.

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

The result is a reliable connection with excellent contact. If it did not 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 the first time is unlikely to succeed.

Video lesson: crimping the RJ-45 connector

Thanks to the advent of the Internet, many problems are resolved quickly enough, especially after reviewing 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 and dispense with ticks. And yet, it is better to play it safe and use the tool for better work.

How to connect an internet cable to an outlet

To begin with, it should be noted that there are two types of Internet sockets, like electrical outlets: for outdoor installation and for indoor installation.

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

Computer sockets may differ in appearance, but they work the same way. All of them are equipped with microknife contacts. As a rule, they are designed to cut through the insulation of conductors, after which a reliable contact is established, since the process is carried out under a certain amplification.

Connecting a computer wall outlet

Almost all manufacturers of computer outlets place a wiring diagram inside, indicating the order of placement of wires, based on their colors. As a rule, both scheme "A" and scheme "B" are indicated. Pattern "A" should be disregarded and focus on pattern "B".

The first step is to install the case on the wall, positioning it so that the cable inlet is facing up and the computer connector is facing down. Although this installation option can be changed, depending on the 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 can only take a few minutes. In this case, once is enough, although the first time it may not work out, 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 8 wires.

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

Connecting an internal internet socket

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 contacts with microknives. It is in this part that the connection is made, after which the case cover with contacts is closed. Each model of such an outlet has its own way of assembly and disassembly.

If you take, for example, a Legrand computer socket, then 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, by which you can determine to which contacts and which wire should be connected. The color coding of the twisted pairs is also indicated here. Before starting the connection, wires are threaded through the hole located on the plate, prepared for the connection process.

To make it clearer, it's better to watch the prepared video.

You can also find a Lezard Internet socket. The construction here is completely different. The front panel is designed with screws, therefore, to remove it, it is enough to unscrew these screws. As for her insides, everything here is fastened with latches. To pull the insides out of the case, you need to pick up an ordinary, small screwdriver and squeeze the clamps.

To get to the contact group and remove it from the case, you need to press on 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, it is enough to pry the side petals with a thin object. You will still have to make some effort, since the latch is quite elastic. At the same time, you need to remember that plastic is in your hands and, if everything is not done carefully, then you can break it.

For greater clarity, it is suggested that you familiarize yourself with 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 outlets. Although each outlet model is designed differently, the connection process is the same for everyone. The most important thing is to master the connection process itself, associated with certain features. It would seem that it would be easier if the connection was carried out using twisting or soldering, which would be available to almost everyone. But at the same time, it would not have been possible to ensure the compactness and accuracy of the connection itself. But such connections have their advantages: you would not have to stock up on "jacks". Although, on the other hand, this method of connection 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, it is really possible to wire a computer network in your apartment or private house. Moreover, such specialists will take a considerable amount for this.

If the connector of the cable with the Internet is broken, then it is not necessary to call the wizard to replace it. You can squeeze everything yourself, just follow the instructions in this manual. It is suitable for any network equipment that uses twisted pair cable - the most common and cheapest. With proper skill, such a connection is made in 5 minutes, even a beginner, with absolute leisure, takes no more than 30 minutes.

You will need a twisted pair cable and an 8P8C (RJ-45) connector. An insulating cap can be purchased for each connector. It is desirable to have a tester and special crimping pliers - a crimper. However, you can cope without such a tool, only the process will take a little more time, but then you definitely cannot do without a knife and a flat slotted (straight slot) screwdriver. Its tip should be small - 10-15 millimeters in length.

The first modification of the twisted pair cable was used in telephone networks, it is designated by the CAT1 category. Any category from the fifth (CAT5) and higher is relevant. The name of this wire connection is due to the fact that there are several pairs of wires inside the thick cable, and in each pair 2 cables are intertwined. This reduces signal interference so that data rates of at least 100 Mbps can be achieved.

If there is a question of buying a new cable, then proceed from the following positions:

1. The higher the category (CAT), the faster and more reliable the data transfer. This is achieved by shielding - covering individual pairs and even wires with a sheath, as well as increasing the number of turns in a pair of wires. All these manipulations are done to protect against electromagnetic interference. In practice, the CAT5e category is most often purchased - the best price-quality ratio.
2. The twisted pair cable is limited in length. This is the key disadvantage of this type of communication. A good connection is not guaranteed over a distance of more than 100 meters. The cables of the advanced categories in this respect differ from the simple fifth category in that they have a relatively high speed at a short distance. For example, in CAT7a up to 100 Gbps at a distance of up to 15 meters, while in CAT5e up to 1 Gbps.
3. The standard wire contains 8 cores. However, there are also cheaper options with four cores, they have a lower data transfer rate. Regarding the difference between them in the crimping scheme, it will be discussed in the corresponding block of the article.

The twisted pair network connector is correctly referred to as 8P8C, although the much more common name is RJ45. Such a connector is simple and cheap, so it is better to buy several pieces in reserve right away. In total, it has 8 contacts for a metal core, which are mechanically fixed. That is, the wires are inserted into the contact sockets of the new 8P8C in the correct sequence, and then the connector body is compressed and a stable structure is obtained in which nothing dangles. Each groove has its own number.

It is necessary to understand the numbering of contacts in the event that a four-wire wire is crimped for the more common eight-wire wires, this is not so critical.

A crimper is a fairly simple tool. The main function is to create the same pressure on the entire connector. In addition, in the crimping pliers, there may also be nippers (built-in blade, press), with which the wire is quickly cut or its outer sheath is stripped.

With a crimper, everything will be easier, but this does not guarantee the quality of the crimp. The main factor is the human hands, because you can even squeeze the connector with your teeth.

Twisted Pair Crimping Instructions

First cut off the twisted pair cable at right angles. All wires must be level so that none of them protrude beyond it. Next, remove the outer shell to a length of 2-3 centimeters (more is possible). It is convenient to do this with a breaking thread - there is a nylon thread inside most cables. It is enough to pull strongly on it so that the insulation can be easily removed, and the wires inside are not damaged.

Split the veins in pairs by color - like to like, one to one. Most likely you will have an eight-core wire, that is, there should be 4 pairs of single-color wires. After that, cut them exactly so that from the outer insulation layer to the end of the core is 1.3 centimeters. This is important so that when crimping, the outer shell is also fixed, and not dangling, which will definitely not add reliability to the structure.

After this preparatory work, proceed as follows:

• Decide on the crimping scheme - a straight line is preferable, but for details it is worth reading the corresponding block of the article, which is just below.
• Carefully insert the wires into the connector according to the chosen scheme. One track is intended for only one core, no twisting is allowed, the cores must lie freely in their own groove until they stop.
• Make sure that the outer insulation of the twisted pair is also inside the connector, if not, shorten the bare part of the cable.
• Gently insert the connector into the corresponding slot of the crimper and squeeze its handles. You should not put much effort, the main thing is that the handles reach the stop, it is useless to squeeze it harder.
• Remember to put the cap on the connector.

If it didn't work the first time, that's okay. A crimped cable becomes uncrimped in a second by cutting off the connector.

3 types are used:

• straight;
• cross;
• cantilevered.

Initially, a straight cable was used to connect dissimilar network devices (router-PC), and the other two for homogeneous devices (router-router, PC-PC). That is, in the past it was necessary to use a suitable scheme. Today, not only computers, but also simple devices, like a household router, automatically determine which crimping scheme is used. Therefore, it is most rational to crimp for an eight-wire wire in a straight line, just follow the color sequence.

If you have a 4-core wire, this does not fundamentally change the circuit, except that the connection is made for the following connector grooves: 1, 2, 3, 6.

Connector crimp without pressing jaws

How to crimp an internet cable if there is no crimper? This procedure is quite simple and is performed according to the following algorithm:

• Everything is done in the same way as previously described. You should have a cable in your hands, the wires of which are correctly installed in the connector tracks.
• The connector is neatly placed on a flat surface with the latch down, the main thing is that it is fixed.
• At one of its edges, you will see yellow latches in the depths - successively push them to the core so that they touch, and the core insulation layer does not interfere.
• Without turning the connector, push it on the opposite side, where there will be a small slot. As a result, the entire twisted pair should be fixed by pressing the outer sheath of the cable with the plastic latch of the connector.

Let's summarize the instructions and highlight the key nuances:

1. Don't overthink your choice of cable. In most cases, the capabilities of mass products are more than enough. Expensive cables are usually used for specific communication purposes.
2. Observe the color scheme for the individual cores. It is only required to carefully repeat what is indicated in the picture.
3. The connector retainer should secure the cable without external insulation. Otherwise, there is a high probability that the crimp will need to be repeated after a while due to damage to the old one.
4. The ends of one cable must be connected according to the same pattern. It is forbidden that a straight crimping circuit is used at one end, and a cross at the other.
5. It is advisable to check the result of the work with a tester. Both ends of the cable are inserted into this device, after which a signal is passed through it. Of course, if the internet already works after everything, then OK. However, in case of any malfunctions, the tester will immediately display in which core or pair of problems - the repair procedure is significantly accelerated.
6. If there is no crimper, then proceed slowly. Better to do everything neatly with one connector in 20 minutes than in a bustle of 40 minutes, ruining a lot of connectors and even more nerves.

Hello dear readers of the blog site. If your internet cable (twisted pair) is bitten by a dog or cat, it is transmitted by furniture or was damaged in another mechanical way, then it can be restored without losing its aesthetic appearance and functional characteristics. Many, remembering grandfather's method, resort to twisting the veins and further wrapping them with electrical tape in the old fashioned way. However, it is not permissible to repair the Internet cable in this way.

This method is well suited for breaking the power cable of devices and devices. Any twisting of twisted pair conductors is additional interference, loss of data packets, which you can then feel during operation (reduced speed, disconnections, etc.). By resorting to twisting, you lose the data transfer speed by an order of magnitude.

This article will describe how to repair an Internet cable in case of a break in the area from the entrance to the apartment and before connecting the device. If you have damaged or broken the connector, then you can read about its repair in a separate one.

This situation can also arise with the cable from the antenna. Therefore, I recommend that you read the article on.

Required tool

To repair a damaged twisted pair cable, we need several tools:

Cable stripper and cutter (stripper)

A stripper is needed to strip a certain piece of external insulation and also to cut off excess conductors. A knife can also be used to remove the insulation. However, be extremely careful not to damage the integrity of the veins.

Wire connector (adhesive tape)

Scotchlocks need as many as the veins need to be spliced.

Connector crimping tool

If there is no such tool, then you can get by with simple pliers. However, as with a knife, you need to be careful, otherwise you may damage or crush the connector.

Internet cable repair (step-by-step steps)

To begin with, with the help of a stripper, we remove the excess insulation in order to free the veins from it (about 2 centimeters). We unweave twisted pairs, for further ease of installation in the connector.

Now, one by one, we take cores of the same colors from different pieces of cable and insert all the way into the connector holes. Then we snap the scotchlock by pressing two fingers. Using the connector crimping tool, squeeze the adhesive tape completely and then the wires will definitely not fall out. This operation must be carried out in turn with all the veins.

As a result of repairing the Internet wire, a small bundle will turn out (as it looks, you can see in the figure below).

It is recommended to wrap this place with electrical tape for additional protection. But before finishing, I advise you to check your work and make sure that the Internet is working. To do this, you need to insert the compressed twisted pair cable into the connector of the device through which the network is organized (stationary computer, laptop or router). If everything works without interruptions, then you can safely protect the place where the Internet cable is being repaired.

I advise you to read the article about. Such a need may arise if you are going to redevelop the premises and the equipment will be moved to another place.

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

Basic concepts

A special type of cable designed 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 of length. The most common is 8-wire twisted pair. All cores are enclosed in a common polyvinyl chloride (PVC) sheath.

Small twisting or twisting is done in order to neutralize interference from electromagnetic radiation generated by the conductors themselves and by third-party sources. Because when the cores are located close, the electromagnetic radiation generated by them is extinguished against each other, without creating signal losses. In addition, external interference is caught by the two twisted conductors in the same way, so it is easily recognized by the receiving device and cut off. The result is a high-quality digital signal with minimal losses.

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

Twisted Pair Types

1. UTP - twisted pairs are not shielded, there is no external shield. The most common type for apartment computer networks, when there are no large interference and distances.
2. FTP - twisted pairs are not shielded, but there is an external foil shield. 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 is encountered.
3. STP - each twisted pair is braided with a wire protective shield, there is an external shield. Used in mid-sized offices and establishments where there may be leads. They allow you to maintain the quality of the signal when transmitting over 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 the 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 at enterprises with high interference and where it is necessary to maintain the speed of information transmission over a long distance.

The color of the cable insulation is gray, which is the most widely used color. Red or orange color means the insulation is made of non-combustible material.

Two ways to crimp twisted pair

The Rj-45 computer cable is connected to the device via the 8P8C connector (abbreviation of the English words 8 positions, 8 contacts). This connector mounts to the cable using an 8-core twisted pair crimp in a color scheme based on telecommunications standards.

The 568-A standard is obsolete and the most commonly used 568-B.

Following the diagram, the cores with the 568-A system are laid like this:

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

The color order for crimping twisted pair according to the 568-B standard is as follows:

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

The connector has eight grooves, where 8 twisted pair wires are laid in a color scheme. The pinout is shown above.

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

Direct twisted pair connection by color

The first way is direct. pinouts of a twisted pair of 8 wires can be made 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 interchanged veins of white-green with white-orange and green with orange. It is used to connect various user devices (computer, TV, laptop) to network equipment (switch, router, hub, router, patch cords, extension cable), and is also used to connect network devices to each other. The information transfer rate with this scheme is 1 Gbit / s.

Direct twisted pair connection 100 Mb / s

In some cases, when a high speed of the Internet is not required and traffic of large volumes is not provided, you can use a connection according to the colors of a twisted pair of 4 cores: white-red, red, white-emerald, emerald. This method saves the consumption of wires, but it must be borne in mind that the highest information transfer rate drops 10 times and is 100 Mb / s.

Crossover Twisted Pair

The second way is cross or cross. Crimping a twisted pair of 8 cores (color scheme) is shown below, it is used to combine 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 veins are swapped: white-red with white-emerald, red with emerald. In this case, the information transfer rate will be only 100 Mbit / s. The Gigabit Crossover scheme involves swapping all eight veins: 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 data transfer rate is 1 Gbps.

Summing up, you can understand that if you need to connect a computer to the Internet, you should crimp both ends of the cable according to the 568 V type. the other is by replacing all eight wires.

How to crimp a network cable?

Now that it has become known how to correctly connect the twisted pair by color, you can start crimping. How to do this is described below.

Tools and materials

Sequencing

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 a notch in the crimper near the handles of the tool. You can also do this with a stripper or a sharp knife, but only carefully so as not to damage the insulation of the cores.

Spin the twisted pairs to make 8 separate cores. They are laid out in a row, according to the color scheme of the pinout of the twisted pair of 8 wires.

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

Insert the connector with the cable into the crimper socket with the inscription 8P. Squeeze the handles firmly but smoothly until they click. If you have a tool on hand, this procedure is quite simple, but if there are no pliers, then you can get by with a flat screwdriver. To do this, you need to put the tip of the screwdriver on the connector contact and push until it cuts through the insulation of the core with its teeth. Do this with each of the eight contacts. Then you should also push through the central part of the connector body - a notch on the connector near the cable entry for fixing. If it didn't work the first time, you can cut off the failed connector and do it again.

Check the quality of work with a multimeter. To do this, set the "resistance" mode on the device. To check the device, close the two probes together, the resistance should show 0 - it means there is a contact. Then put one probe in contact at one end of the cable, and the other probe on the corresponding color contact at the other end. If it shows 0, therefore, there is a connection, everything is fine. If it shows 1 or so, then the teeth did not break through the insulation, you should either push the contacts again, or cut and do it again.

You can check the quality of crimping twisted pair of 8 cores in another way. Ring the sequence of wires with a special network tester. How to use it is written in the attached instructions. And you can also connect the ready-made patch cord to the equipment and check if all the packets are being received.

Hello dear readers of the blog site. Today I want to talk about how to lengthen the Internet cable in an apartment on my own. Very often this type of service is provided by a provider, but naturally he will take a separate fee for this (depending on the length, the price can vary from 500 rubles to infinity)

Usually, such a need arises if you decide to move the equipment (computer,) further than the previous place, and when laying the wire, the provider did not leave additional footage in reserve.

There are two ways to lengthen yourself:

• Increasing the length of the cable using wire connectors (adhesive tape) and re-crimping;
• Using a splitter.

Let's take a closer look at both options.

Build-up using wire connectors (tape) and re-crimping

Now everything is in order. Before you build up an Internet cable, you need to first understand how you will lay it (under a plinth, above a false ceiling, or just along a wall or floor). Having decided on the option of laying, calculate how many meters are needed. When buying a wire, do not forget to buy it with a margin of a couple of meters. Also purchase RJ45 connectors and wire connectors (tape) from the store. Everything that you buy yourself, in any case, will be cheaper than you order a visit of the master to carry out these works.

And so, having brought all this home, we proceed to work. First, you need to cut off the existing connector on your cable and remove the outer protective insulation.

Note - do not throw out the cut connector until the end of the work, it may still be useful to us.

The same actions must be performed with the purchased cable (the side from which you start is absolutely not important). I will not describe this process here, since you can read more complete information in the article If you did everything correctly, then at this stage you should have a spliced ​​wire without a connector at the end.

The next stage of work will be to crimp the Internet cable using an RJ45 lug. To do this, we need to remove the external insulation a couple of centimeters long, untangle the twisted cores, and picking up the cut and new connectors, understand by the colors which cores should be laid in the connector in what sequence. You can read more about all the stages of crimping in the article.

Now, having received the finished elongated twisted pair, we check its work. Insert it into the connector on the computer and check if you have a network and, accordingly, the Internet. If you have built up the wire correctly, then the network will appear immediately and you will only have to wrap the junction with electrical tape for additional protection from physical influences. It may happen that the network does not appear, then check the connections more carefully and eliminate all the shortcomings.

This extension option is more laborious than using a splitter.

Extension of the Internet cable using a splitter

Everything is much simpler here. You need to purchase from the store a patch cord of the required length with already crimped ends (the only thing, it can cost more than if you crimped it yourself), as well as the splitter itself.

The dimensions of such a box are not large, but unlike the first option, you will not be able to remove it behind the baseboard or under the floor. It will be necessary to choose a place so that it does not interfere and spoil the aesthetic appearance.

First, you need to disconnect the wire from your device and insert the connector into any of the two splitter sockets, then insert a ready-made or self-made cable into the free socket, and, accordingly, insert the remaining free end into the socket of your device (laptop, computer, etc. .).

If you lengthen the Internet cable in this way, then in fact there should not be any problems, the only thing that may be is the cable is not properly crimped or a defective box is found.

If you are going to make repairs in your apartment, then I advise you to be puzzled in advance by the issue of placing computer outlets in your house, and you can read about how to connect them in a separate one.
