How to connect a network cable. How to lengthen the internet cable (network cable)? Crimping cable with direct connection

Twisted-pair extension with simple tools at hand, with minimal time and resources. This material will provide convenient, step by step algorithms actions, for lengthening power cords for any purpose, these methods are suitable not only for fixed cables that the provider installed, but also for any other, additional types of power cords.

The extension of the network Internet cord, laid by the company of the Internet provider, connecting the hardware resources of their company with the user's PC, is the most requested request at the present time. In this article, we will consider ways to lengthen twisted pair cords, without using a twisted pair crimping tool, for fiber optic cables, this material will be irrelevant.

The need to lengthen power cords occurs quite often when carrying out household repairs, rearranging peripheral devices and various equipment, moving furniture and other household conditions. In such situations, the problem arises that there is simply not enough cable length, of course, there are several ways out of this situation: contact the services of a provider company or specialized offices, adjust to the length of the existing cable, and perform work and rearrangements regarding the available capabilities, or else use the simplest and most convenient options - to perform an independent "pointing" of the power cord. Before you start working with the cable yourself, we recommend that you familiarize yourself with useful tips:

1. If it is necessary to extend the standard power cord that connects the computer to the router, a more rational option may be to purchase a new cable of the required length, at a price it will cost a little more than an elongated one, and at the same time its reliability will be higher. Since any artificial connection, through additional connectors and plugs, and even more twisting, are not reliable enough in operation. You can crimp a twisted pair cable in almost any digital technology salon;
2. In case the router has not yet been placed in the room, you should consider the option of installing it, perhaps this option will become more convenient and rational for your situation, unlike laying a new cable, especially if it is built into walls or laid in other non-surface ways. If there are stationary type computers, they can be connected to the router either by laying an additional cord or by installing a special adapter for receiving “Wi-Fi” signals. Such adapters are quite convenient, mobile and slightly expensive;
3. If the situation has developed directly around the connection of the power cord, you can contact the representative office of your Internet provider and explain the situation, they will be able to offer you the most appropriate and rational solutions to your problem. Often they go to meet their customers, and provide free services for replacing the cord, or carry out work at a discount, etc.;
4. If the room is equipped with Internet outlets, you can consider solving the problem by using these outlets.

If the only or necessary option is to extend the cord, the best way is to use special connectors. With proper observance of all measures of the procedure, the end result will be of sufficient quality. Using the twisting method is the most unacceptable option (possibly unstable connection), and are acceptable only as a temporary measure, if you need to extend the cable urgently, but all the necessary elements are not at hand.

Extending the cord with a connector adapter

This method is universal and can be used to connect the main cable from the provider, or to combine the cable of a PC, modem, router, etc.

Such adapters are called joyners, they are quite simple in execution, they look like a two-way connector for a power cord plug. To use this adapter, it is necessary that the ends of the cables are crimped and equipped with connectors. This operation can be done using special devices, or ordinary household tools.

Using this method, in the process of purchasing a network cable, you can ask to compress it directly in the service, this operation is done in all stores selling such products. Having an adapter and crimped cables, the further connection process is quite simple, you need to connect the cable to the connectors of the adapter and that's it, the job is over.

As an analogue, you can use adapters of the type - couplers, they are quite convenient, and even much easier to operate than adapters of the type - joyner, since when using them there is no need to carry out such an additional operation as cable crimping. They are often confused with splitters, this point needs to be given special attention.

Adapter type - coupler

Cable extension for PC, TV, modem or router

If the power cord is not long enough to connect a modem, router, or any peripheral devices, you can use all the same adapters for network cables. But do not forget that lengthening the cable in any way will always be less the best option, compared to a full-fledged cord, and, if possible, try to use them, or connect devices via wireless systems.

Connecting the power cord by twisting

As previously stated in the article, this method is not the most reliable ( network connection may be unstable, and disappear from time to time), however, it is also in demand, especially in cases where it is necessary to briefly connect two cables, thereby extending the main cord.

This method is not difficult to perform, it is necessary to carefully and at the same time carefully strip both end sections of the cables, and carefully twist them in accordance with the color of each of the branches. Each individual branch must be insulated without fail, using an insulating tape, or special heat shrink tubes. The most difficult moment in this operation is the stripping and twisting of the branches, the wires in the power cords are quite thin and fragile, and they often break.

For a more reliable connection, during the twisting process, you can use adhesive tapes, they are small connecting blocks that are easy to use and quite cheap (100 pieces cost about $ 4, in some stores they are sold by the piece and will cost a penny at all).

Having twisted all the cable cores and insulated each of them separately, for greater reliability, it is necessary to insulate the cable junction itself. When using adhesive tapes, insulation of individual cores is not needed, since these elements serve as both connectors and insulation, and general insulation of the connection will not interfere with water, as with the standard twisting method, this will save this connecting segment from breaks, fractures and other mechanical damage. Any of the above methods can be used not only to lengthen network cables, but also to repair the cable, for example, in the event of a clearly established damage (fracture, pinching, cable break, etc.).

In this article, we will look at several ways in which you can extend the Internet cable. DIY (using twist) and without additional devices, or with minimal cost (with adapter). Following the instructions in this article, you can also extend the network cable that you use to connect your computer to a router, or for other tasks. Not only the cable that the Internet provider has laid in your house.

Most often, it becomes necessary to extend the Internet cable that enters our house or apartment from the provider's equipment. Please note that we are talking about cable. If you have, for example, fiber optics, then the solutions from this article will not work. Very often during the repair process, when rearranging furniture, or moving devices, it turns out that the Internet cable is short and does not reach our computer or router. There are not many options in this case: adapt to the length of the cable, ask the provider to lay a new cable of the length you need (which they are unlikely to do), or just finish the internet cable. What are we going to do now. But first, a few tips:

• If you want to connect a regular network cable that you use to connect two devices (e.g. PC with router), then it probably doesn't make any sense. It is easier to make a new cable of the desired length. It will be easier and the cable will be more reliable. Since any connection, and especially twisting, is not very good. You can make such a cable with your own hands, or ask to compress the cable of the desired length in some digital equipment store.
• Perhaps in your case it makes sense to install (if it doesn't already exist) rather than lengthening the cable and laying it through the entire apartment. And if there are stationary computers, to which a network cable is most often laid, then they can be the same. You only need a Wi-Fi adapter, which I wrote about.
• If we are talking specifically about connecting an Internet cable, then you can call your Internet provider and explain the situation. That you do not have enough length of the network cable laid in the house. Perhaps the provider will offer you some reasonable solution. For example, they will send specialists who will replace the cable for free.
• Internet sockets. If they are installed in your house / apartment, then consider possible options connections using these sockets.

If you cannot do without a network cable connection, then it is best to use special connectors (coupler, joyner). If everything is done correctly, then the quality of the connection will not suffer. I do not recommend using twists. They create additional resistance and this can greatly affect the stability of the connection. And as a result on speed and a ping. A computer or router may simply not see such a cable.

Extending a network cable using an adapter (connector)?

This method is suitable in all cases. Both for connecting a network cable through which the Internet enters the house, and for extending a network cable for a computer, TV, router, modem, etc.

These connectors look like this:

They call him Joyner. There's just a cable entry on both sides. (for RJ-45 connector). Mother-mother type. To connect a cable using such a LAN connector, it is necessary to crimp the cable on both sides into an RJ-45 connector. How to do it with my own hands without a special tool, I wrote in the article. If you have a special tool (crimper), everything can be done according to these instructions:.

If you use such a connector in order to extend the Internet cable, then you can buy a second piece of cable in the store. It will be ready (with connectors). If there is no cable of the required length, then this cable can be made for you. Ask in stores that sell computers and other computer equipment.

Simply connect two network cables to such an adapter and you're done.

Suppose, on the one hand, we have an Internet cable from the provider, and on the other hand, the second piece of cable that we made ourselves or bought in a store.

There are slightly different LAN cable connectors - couplers.

With their help, extending the LAN cable is even easier and more convenient. No need to crimp the cable into the connector and no special tool needed. Only a screwdriver.

Do not confuse these connectors with splitters. They have one entrance and two exits. And they are designed for other tasks.

If you need to extend the network cable for a computer, TV, router

When there is not enough length of the network cable to connect a computer, TV, another router or some other device from a router or modem, you can also use connectors. But do not forget that you can always buy or make a longer cable, or connect the device via Wi-Fi. Perhaps in your case this solution will be more correct and convenient.

Of course, you can take two pieces of twisted pair crimped on both sides into an RJ-45 connector and connect them through a connector.

With this cable, you can connect absolutely any device that has a LAN input to the Internet.

We connect the Internet cable using twisting

I already wrote above that this is not the most The best way to which you can connect the network cable. The quality of the connection may suffer, or even not work at all. But if there are no other options, or you need to do everything urgently, then you can try.

Simply strip the cable at both ends and twist it color to color. For insulation, use electrical tape or heat shrink tubing. It is necessary to twist each cable securely and insulate.

I did everything for the first time. The most difficult thing is to strip the veins and twist them. They break sometimes. First we remove the outer insulation, and then we clean each wire.

I think it can be done more neatly than I did. After the network cable is twisted, each wire must be insulated. I used heat shrink tubing. Electrical tape will work too. That's what I did:

Believe it or not, this cable even turned out to be working 🙂

Just be careful with it, the veins are very fragile without insulation. They are easy to break and the cable will not work. You can wind the cable lower so that the connections do not move or break.

Write in the comments what method you use to extend the network cable and how everything works for you.

Modern technologies have led to the fact that today almost every home has Internet. The World Wide Web has become an integral part of our daily lives. The main and most common way to connect to the Internet is through a local area network. The computer is connected to the Internet using a network cable. There are situations when the cable is not enough to move the computer to the right place. You can read about how to build an Internet cable in this article.

How to extend the wire: 3 options

It is very inconvenient to use the Internet when there is no possibility to move freely. Many build up a network cable to make using the Internet more comfortable. There are several easy ways to extend the cable.

One of the ways to extend the Internet cable is to buy a special patch cord and a joyner (twisted pair connector).

When buying, it is important to pay attention to the appearance of the joyner, as it is very similar to a phone adapter. It will not be difficult to distinguish a twisted pair, since the adapter has 8 pins, while the telephone adapter has only 7. A computer network card is inserted into the patch cord, the other end of the cord is connected to a network cable.

Internet cable extension options:

1. Router. Convenient and reliable extension option. The router has a couple of sockets to which you can connect a network cable. Router - "splitter" of the Internet. It allows not only to extend the cable, but also to connect additional devices to the channel. You can refuse the cable altogether if you purchase wifi router.
2. Purchasing a new cable. The old cable can be replaced with a new one by simply measuring its length beforehand. This method is time consuming, as you will have to call a technician to reconnect. But if we are not talking about a multi-storey building, but about a private one, then the method is quite suitable.
3. Performing a twist. Masters do not recommend using this method. It involves cutting the cable, and then inserting an additional piece of the required length into it. Two segments must be connected with electrical tape.

Twisting can lead to short circuits, which will lead to a disruption in the speed of the connection or the complete absence of the Internet. The most reliable and modern way extending the cable is to use a router. If you are not sure that the self-lengthening attempt will be successful, you can always contact your Internet provider for help.

It often happens that the master interrupted the wiring, performing repair work. When working with a grinder or other tools, some may accidentally cut an electrical wire laid in the wall. Damage is indicated by sparks that appear, a power outage or knocking out traffic jams.

The fact that the wiring is broken is evidenced by broken sockets and the lack of lighting in the area that is located behind the damaged wiring.

The wires located in the installation box may also break. Often there is not enough length for their correct connection. It should be noted that experts advise not to repair one wire, but to replace the entire damaged area. Of course, this method is suitable for those who are not afraid of damage. finishing materials and ready to renovate.

How to build an aluminum cable:

1. Twist the ends of the cable if they are long enough. The twist must be wrapped with electrical tape. This method is the most unreliable, because the twist can break again, which will return the problem.
2. At the ends of the wires, you can put a special heat shrink tube. This method is suitable for connecting and extending any cable. In order to perform plantings correctly, the tube must be heated.
3. All types of wires (copper and aluminum) can be extended using a block. The ends of the cable must be stripped, and then pick up the block.
4. If the wires have broken off, they can be repaired using a spiral. It is screwed onto the ends of the wires. After the desired density is reached, you need to make the insulation of the wires.

Extending a twisted-pair cable does not require special skills, and if done correctly, it can even be reliable. When twisting wires, you need to follow the rule of one level and insulate each individual connection. An interesting method is the displacement of joints made by twisting or soldering.

5 ways: how to extend the wire in the outlet

Sooner or later, everyone is faced with the fact that the wiring breaks. Long service life of the wiring leads to damage or breakage of the wires. Wires can be damaged in the most unpredictable places.

Often, wire breakage occurs when connecting sockets (very often this happens with aluminum wires).

The electric cable in an apartment or house can be extended independently. To do this, you need to make sure that the cores of the conductors that are spliced ​​consist of the same material (it can be copper or aluminum). There are five simple ways to help solve the current problem.

Five ways to lengthen the wire:

1. Adhesive pads. With their help, you can build up and connect electrical wires. This method is suitable for connecting conductors with various metal conductors.
2. Connecting pads. Their use lengthens the block.
3. Twisting lived. The damaged end of the wire must be at least 30 mm, then the splicing will be reliable.
4. Soldering. To do this, you need a welding machine. This method is suitable for building conductors with a large cross section.
5. Sleeves. It's not very convenient way, which takes enough a large number of time.

The twisting method is the most common. It is used to repair headphones, TV, refrigerator, electric stove, etc. When doing work yourself, it is important to remember safety precautions.

If the cable is not long enough to put the TV in a convenient place, you can extend it yourself. It will be quite difficult to completely replace the cable. Of course, you can use an extension cord, but there are times when this is not possible. There are several basic ways that you can choose based on personal knowledge and skills.

You can use a TV extension cable, an adapter, or get ready to work with a soldering iron and soldering.

When purchasing an additional television cable, it is important to pay attention to its brand. To connect two cables, you will need plugs, wrapping and an adapter. It is important that the plugs are correctly sized.

Lengthening Tips:

• Cut the cable sheath lengthwise a few centimeters.
• Unscrew the shell in reverse side and remove where the incision begins.
• Bend the aluminum screen.
• Screw the wires, which already have plugs, to the adapter.

This scheme can be used to extend the cord for a stove, electric kettle, etc. A broken cord can always be repaired. To extend the wire, it is desirable to use a terminal. But when performing work, it is important to strictly observe safety precautions. To splice several wires, you must first learn the technology of extending the wires. You can also build up the power cable yourself, for this you need to use an extension technique. So that during repair work n spoil the floor, you can lay a sheet on the floor.

Instructions: how to build an Internet cable (video)

Modern man cannot imagine himself without electronic devices. In everyday life, he uses a computer, TV and other devices that run on electricity. It often happens that a computer or television wire is not convenient enough to use, since its length is small. This introductory article showed how to extend the wire. It is important to understand that incorrect actions can lead to equipment failure. Sip can be increased in several ways - each master can choose the most convenient for him.

In our age, every apartment, house, and some have dachas have Internet access. Connecting to the World Wide Web has long become the norm and a vital necessity, and now I am writing these lines, sitting at a table in the garden. The main way to connect to the Internet now is the provider's local networks, which are physically connected to our computer or laptop using a network cable - an eight-wire twisted pair.

Often there is a situation when the computer needs to be moved to another place, and the network cable may not be enough for this move. How to extend the Internet network cable so that it lasts to a new place?

Option one - joyner and patch cord

This method is simple and reliable. To increase the length of the cable, we simply buy a patch cord (see the figure) and an RJ-45 twisted pair connector, or joyner. These computer little things are sold in any store, and they cost mere pennies - when I bought them quite recently, the joyner cost 22 rubles and a three-meter patch cord 60 rubles.

By the way, a telephone adapter and an RJ-45 twisted-pair adapter are outwardly indistinguishable - so do not confuse. The telephone has 7 contacts and the computer has 8 - you can count just in case.

So, we insert the patch cord into the computer's network card, and the other end into the joyner, to which we connect our network cable - everything works.

Option two - router

This extension option is convenient and no less reliable.
To connect using the second method, we need a router that we connect to the Internet. The router has several sockets for connecting a network cable, and thus is a kind of "splitter" of the Internet. With it, we will not only extend the cable, but will also be able to connect additional devices to the Internet from one channel. If you choose a Wi-Fi router, then you won’t need cables for your computer at all - I recommend it for a laptop that is constantly moved from place to place.

Option three - new cable

Simply take a new network cable of the correct length and plug it in. The option is not entirely convenient, since you need to call the provider's technician to include a new cable in the equipment - you won’t climb into the attic to look for where your apartment is connected, right? But for homeowners, this method is suitable.

Option four - twist

I must say that extending the network cable with a twist is far from the best solution, and it is better to use the methods indicated above. You simply cut the cable and insert the length you need, insulating the wires with electrical tape according to the colors. Any signalman will point out to you the disadvantage of this connection method, and he will be right - short circuits will inevitably occur in the twist and the connection speed may suffer.

So use reliable and simple ways- a router or a connection using an RJ-45 adapter, and Internet access will remain the same quality as it was.

Twisted-pair Internet cable has firmly entered our daily lives. Like everyone around us, the cable sometimes fails. A typical situation when working with a twisted-pair network cable is when there are only a few meters left to the connection point, and the cable is literally a couple of meters away, either your pet enjoyed the cable from the provider with pleasure, or the cable is easily damaged during repairs or simply by negligence. In such cases, the twisted-pair cable must be extended or spliced.

Many services and craftsmen will come to your aid. But this problem It is quite possible to fix it yourself, saving time and money. Consider 4 ways to lengthen the Internet cable with your own hands.

Joyner and patch cord detachable connections

This option is simple, accessible to most audiences and does not require special knowledge. To extend the length of the cable, we simply purchase a patch cord and the necessary special sockets and RJ-45 plugs (joyner). Such computer connectors are sold for a small price in almost any office equipment store.

It is worth recalling that an ordinary telephone adapter and the RJ-45 twisted-pair adapter itself are practically indistinguishable in appearance - so be careful not to confuse. As a rule, the telephone has 7 contacts, but in our case, that is, the computer 8 can be counted upon purchase.

The most significant drawback is special equipment (crimper) for crimping connectors, and these are additional costs. And the contact area is smaller compared to following methods, and reliability, service life and tightness are not at the highest level.

This technique is widely known in almost all areas where the cable is used. The method is available to everyone who confidently holds a knife and electrical tape in their hands, while providing good reliability. In time, such a build-up may well serve the entire service life of the cable itself. Speeds up to 100 Mbps are maintained in sections up to 100 meters, as well as on entire cable sections.

Often twists are made at the same level, and each posting is isolated separately. However, there is a more reliable wire connection technology. It is very common among telephonists, system administrators, installers, etc., people who often face the question of how to lengthen an Internet cable with their own hands. The main idea is to connect the cable at different levels to eliminate the possibility of contact between the stripped wires.

It is necessary to release about 10 centimeters of the cable from the outer sheath. A split nylon thread is provided inside the cable, so it is quite enough to make a small incision, find the thread and then use it to clean the sheath. The same procedure must be done with the second piece of cable. The sheath cut along the cable should not be finally cut off, we will use it again when the connection is ready.

We clean each wire of twisted pairs by about one centimeter, not forgetting to make sure that, according to the location of the twist, they cannot touch each other. Stripping the wires will require patience and accuracy, the main thing is not to cut the copper wires. Also, one should not neglect the folk wisdom “Measure seven times, cut once”, it is better to strip the wires gradually after you finish the next twist. If you still do not have enough experience in stripping cores from insulation, it makes sense to practice on an unnecessary piece of cable.

We apply the two stripped ends of the wire crosswise and twist with our fingers. It turns out something like a "pigtail". When connecting copper wires to each other, it must be remembered that both wires must be twisted together. And it is not permissible for one of the wires to remain straight, and the second twisted around it. After we have made the twist, bend it in half and press it with round-nose pliers to ensure mechanical strength.

It is advisable to insulate each twist with an insulating tape for greater reliability and tightness. Next, the wires are laid in the sheath of one of the cables and covered with the second. To give strength and a finished look, we tightly tighten the junction with an insulating tape and the work is ready.

Twisted pair cable extension and soldering

This method is the most reliable, especially for radio mechanics, and is available to many. However, it is necessary to have experience in soldering. If the place of the planned connection is far from the current source, for example, the attic of the house or the entrance, and there is no way to use an extension cord, a mobile soldering iron will come to your aid.

Before splicing twisted pairs by soldering, we prepare the cable in the same way as when splicing twisted pairs by twisting (see above). The only difference is that the wires do not have to be twisted, it will be enough to hold them next to the cable overlap of 5-6 millimeters. Or you can make hooks at the ends of the wire and hook them together for further convenience when soldering.

The soldering process itself requires accuracy from the performer, since it is easy to damage neighboring wires with a heated soldering iron.

After soldering, we will insulate the wires for greater reliability. Then we fit the wires into one of the outer shells, and cover the second one on top. We isolate the junction with insulating tape for greater tightness and a better aesthetic appearance.

The considered methods can be applied not only to a twisted-pair Ethernet cable. The same principles of building and extending are suitable for a wide variety of cables, whether it is stranded or solid wire for a wide variety of applications.

Internet cable extension router

This method of building is also quite convenient and practical. By connecting a router, you can connect an unlimited number of laptops, computers, etc. to the global network. (but still within reason).

To extend our Internet cable by this method, we will need to purchase the router itself and a necessarily crimped twisted pair (Internet wire) of the required length. If necessary, you can buy a ready-made crimped piece of such a cable; in some cases, twisted pair is crimped in a specialized store. But even if not, then you can easily crimp the twisted pair cable with your own hands.

Now the Internet cable should be connected to the WAN port (Internet port) of the router, and directly crimped twisted pair to a simple LAN port of the same router and then to your laptop or computer. It remains only to carry out simple router settings, after which you can use the network without problems as before.

V last years wireless internet connection is becoming more and more popular. Many people have started to use a wireless connection at home (using a modem and a SIM card, for example), but most still prefer a wired connection. And no wonder: inexpensive tariffs, high-quality connection, high communication speed.

With this type of connection, there are practically no problems. However, sometimes unusual situations arise. For example, a cable problem. So, its length may not be enough to move the cable to another room. Therefore, today we will talk about how to extend the cable.

In local networks, the so-called twisted pair is used - this is one of the communication cables, which consists of several isolated conductors. The category is always indicated on the cable. To connect the cable to the equipment, the 8P8C connector is used, which is often called RJ45, which, in general, is the same thing.

Now let's talk about cable extension.

Extension with adapter

You will need to purchase a patch cord. A patch cord is a cable or a patch cord manufactured in the factory. For example, you can purchase a patch cord for 5 meters, which would be enough to transfer the cable to another room.

In addition, you will need to purchase a twisted-pair adapter or, as it is also called, an RJ45 joyner.

Insert the patch cord into one connector, and your already crimped cable into the other. This is one of the most convenient and simplest ways to extend the Internet cable.

Extension with twist

In this case, as you may have guessed, you will need to purchase a cable of the required length and twist it yourself. This is not so difficult to do, especially if you have even a little experience, but you need to twist it very carefully.

It is believed that part of the signal is lost when twisting the cable. This is true if the twist itself is made anyhow. In addition, in some cases, a wire break inside the strand may occur, as a result of which the connection may be lost.

In general, this is not the most ideal way to extend the cable, so it should be used only in extreme cases.

Buying a router

You can connect multiple computers to the network with a purchase. To do this, connect the main cable to the device to the WAN port, and connect the patch cord to the LAN port, which you connect to the other connector the right computer. Very convenient and inexpensive.

Of course, do not forget that with the help of a router you can easily establish a wireless connection to which you can connect various devices that support a Wi-Fi connection.

You may need to compress the cable for the Internet with your own hands for various reasons.

In some cases, it is necessary to replace a broken tip on the provider's wire because it has worn out.

Someone is trying to connect a PC to a router using twisted pair. Some people look for this information when they want to set up a local area network at home.

In any case, before proceeding to the very process of building a network or repairing a wire, you need to understand some things.

For instance:

• What types of twisted pair are and what is it. Otherwise, how to figure out which wire to buy?
• What is required to crimp a cable? You need to understand what connectors and tools are currently being used.
• What types of crimping are there? The type of crimping depends on the purpose for which it is necessary to crimp the cable.
• How to compress an Internet cable at home? Surely not all ordinary users keep special equipment at home.

After reading this information, you can be sure that the process of twisted pair crimping will become simple and clear. You can easily restore your Internet connection or combine home computers into a local network.

Definition

Twisted pair is one type of communication cable. Most often used in the creation of computer and Internet networks.

Extremely cheap production and ease of installation ensure its widespread use: in offices, apartments, telephony, television.

There are single-pair cables (only two braided wires are used inside) and multi-pair cables - more than two pairs of conductors.

What to use at home

Cable product standards for types of shielding

In home and office environments, a (typically) 4-pin cable is used.

The cheapest type of all is UTP cable.

It does not have any shielding, it is usually laid in walls, cable channels and is very sensitive to any electromagnetic radiation.

More advanced is the FTP standard cable. Inside, a shielding winding is used for all cores of a twisted pair. Such a protection scheme makes it resistant to electromagnetic radiation and can be used for internal external work, depending on the material of manufacture of the outer shell. It can be laid both in the cable plinth and along the walls on the fasteners.

The most secure standard is STP. It has a screen for each pair of cores separately and a common screen in the form of a grid. Very often used in industry and data centers.

Bandwidth Categories

Twisted pair is also divided into categories, depending on its bandwidth.

To create a home local network just use cat 5 or 5e. In company offices, 5, 5e are usually used, less often 6, 6a, and 7 and 7a.

• Cat 5- pairs operate at a frequency of up to 100 MHz, pass up to 100 megabits per second;
• cat 5e- pairs with an operating frequency of up to 125 MHz, transmits up to 1 thousand megabits per second (1 gigabit per second) .;
• Cat 6 and Cat 6a- pairs operate at a frequency of 250 and 500 MHz, respectively, can transmit up to 10 gigabits per second;
• Cat 7 and 7a- pairs operate at a frequency of 600 and 1200 MHz, respectively, can pass up to 100 gigabits per second.

The most popular of them at the time of this writing is the FTP Cat 5e twisted pair, because it can pass data at speeds up to 1 gigabits / sec and is quite cheap. It is this cable that should be purchased to create a local computer network or connecting a PC to a router.

What is twisted pair crimping

Twisted pair crimping or crimping is a process during which the cable is stripped of outer insulation, the strands are straightened and untwisted, and then installed in the 8P8C connector (aka RJ45 connector) and clamped.

This procedure may be needed in several cases, for example:

• the connector on your internet cable is broken;
• you decide to connect two computers to a wired local area network;
• you need to connect your computer to the router via cable;
• it is required to extend the wire through;
• and in many others.

It is not difficult to crimp an Internet wire at home, however, for an ideal result, you will need some tools and accessories, namely:

• twisted pair of the required length;
• press tongs (crimper);
• one or two connectors (it is better to buy a few in reserve).

At the moment, two types of cable crimping are used. One of them is called straight and the other is called cross (or cross crimp). They differ in the pinout of the cores in the connector and their application in practice.

Straight straight crimp or "computer hub"

This type is used to connect two different types devices, that is, when connected:

• computer to router
• TV to router
• computer to the switch;
• router to switch
• computer to modem.

It is called "straight" because on both plugs the wires in rzh 45 will be arranged in the same order:

This type of pinout is used for connections with data rates up to 1 Gbps. At home, most often straight crimp is used to build a local network over a fiber optic cable.

Since most providers offer rates up to 100 Mbps, they use a different wiring, in which only 1, 2, 3 and 6 cores are involved.

If you are repairing an Internet cable run by installers, you will have to use this option:

Always carefully inspect the patch cord that the provider is laying.

If they use a two-pair crimp, provided that you can re-crimp for all 4 pairs, this will not add speed to you, but it will provide trouble with stuffing all 8 wires.

Cross crimp or "computer-to-computer"

Used to connect devices of the same type to each other, for example:

• computer - computer;
• router - router;
• TV is a computer.

It is called so because of the cross arrangement of the cores in the connector. One end is crimped, as with a direct connection, and the other in a modified sequence.

When cross-crimping, all 8 cores are always taken, the figure shows a method that allows speeds up to 1 Gigabit / s. If the equipment does not work with this bandwidth, then the speed will be reduced.

Now that we have managed to decide which patch cord to use, figured out the necessary pinout and how many strands to use, we can proceed to the process itself.

Use of ticks

The most correct option when crimping the RJ-45 plug and twisted pair is to use special pliers.

In professional language, they are called crimper.

The name comes from English word crimper - to crimp.

Why it is worth crimping with crimping pliers:

1. Convenience - they have a convenient form and are so easy to use that everyone can use them.
2. Saving time - all types of nippers are collected, which will allow you to carry out three procedures with one tool.
3. Safety - it is impossible to harm yourself with them, only if you do not specifically stick your finger into the cutting pliers.

Everything is ready, now we start crimping.

For this you need:

1. Bite off the old connector, it can be used as a pinout pattern. If this is not the case, then you can proceed to the next step.
2. Strip the wires from the outer sheath. The length of the stripped wires should be equal to the length of the connector or slightly less, but not more. You need to measure the length from the cut edge and insert the wire into the stripping area. Now you should bite the cable, remove it from the pliers and remove the outer sheath.
3. Colored cores, as we already know, are twisted inside the cable. They must be carefully untangled and aligned. If their length differs, then it is necessary to shorten too long ones.
4. Without inserting into the connector, it is necessary to arrange the wires in the sequence in which the crimping will be carried out.
5. Next, you need to insert the wires into the connector. It should be inserted so that part of the outer braid climbs inside. In this case, the plug will be strong and the cable will not fly out during use.
6. Next, you need to carefully place the cable with the connector into the area for crimping the network cable and firmly squeeze the crimper handles. During this movement, the blades of the tongs open the connector terminals, which cut through the insulation of the conductors and fix them in the connector.
7. The last step is to check that the work is done well. Move the rzh 45 connector, if no wires have jumped out of their places and it has not fallen off, then everything is fine.

Install the crimped cord into the port and check for a connection. If the LAN or WAN port lights blink, the Internet appears, or the desired device appears on the network, the cable is crimped correctly.

Screwdriver application

Using a crimper for crimping is professional. However, not everyone has it available.

For such a case, there simple instruction how to replace an RJ45 jack with a screwdriver at home.

The preparatory sequence is the same as in the previous version:

• cut off the connector, if any;
• clean from external insulation, for example, with a knife and;
• align the length of the wires;
• arrange the cores in accordance with the desired wiring;
• plug the wire into the RJ45 plug.

Further, it is necessary to check how the conductors got up. If the order is followed and everyone is in their own track and touches the golden terminal, we proceed to crimping. You need to put the connector on the table so that the latch is at the bottom. Take a screwdriver and push on the mount in the connector, which will fix the cable itself in the connector.

After that, with the same screwdriver, it is necessary to alternately push the terminals of the connectors one at a time. It is necessary to do so that the contact of the terminal pierces the insulation of the core and becomes one with the wire.

You need to perform this step very carefully and calculate the force with each press so as not to pinch the terminal and break the connector.

Once all 8 cores have been clamped, you need to check the work.

This can be done in different ways, depending on the purpose for which the crimp was made.

If you made a wire to connect the computer to the router, then connect one plug to the WAN connector on the router, and the second to the Ethernet connector on the PC. If the results are positive, the lights will “blink” and you will be able to establish an Internet connection.

As practice shows, it is absolutely not difficult to make an independent repair of an Internet cable. This procedure does not require any special knowledge, the main thing is to figure out which wire wiring will be used.

The rest is a matter of technology, you can crimp the Internet wire using a special crimp or limit yourself to a simple screwdriver. Of course, in the first option, this can be done faster. But the main feature of the second is not to buy a tool. The method is especially relevant for those who do not need to do this work all the time.
