Clicking the Internet cable with your own hands may be needed for various reasons.

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

Someone is trying to connect PC to the router, with a twisted pair. Some are looking for this information when they wish to create a local network at home.

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

For example:

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

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

Definition

Twisted steam is one of the types of communication cables. Most often used when creating computer and Internet networks.

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

There are single-page cables (only two woven wires are used inside) and multi-part - over two pairs of conductors.

What to use at home

Cable Product Standards Screening

In domestic and office conditions, a 4-pin cable is used (usually).

The cheapest view of all is the UTP standard cable.

It has no shielding, it is usually paved in the walls, cable channels and is very sensitive to any electromagnetic radiation.

More perfect is the FTP standard cable. Inside, the shielding winding of everyone lived a twisted pair. Such a protection scheme pretends to be resistant to electromagnetic radiation and can be used for internal external works, depending on the material of the manufacture of an outer shell. It can be laid in both cable plinth and walls on fastenings.

The most protected standard is STP. It has a screen for each pair lived separately and the shared screen in the form of a mesh. Very often used in industry and data centers.

Bandwidth categories

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

To create homework local network Enough to use Cat 5 or 5e. In the offices of companies, 5, 5e, less often 6, 6a, and 7 and 7a are usually used.

• Cat 5. - Couples work with a frequency of up to 100 MHz, passes up to 100 megabits per second;
• Cat 5e. - pairs with a working frequency up to 125 MHz, skips up to 1 thousand megabits per second (1 gigabit per second).;
• Cat 6 and Cat 6A- Couples operate with a frequency of 250 and 500 MHz, respectively, can pass up to 10gigabit per second;
• CAT 7 and 7A - Couples work with 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 writing the article is the twisted pair of FTP Cat 5e, because it can pass the data from the speed of up to 1 gigabit / s and at the same time finding enough. This cable should be purchased to create a local computer network Or connecting a PC to a router.

What is obshant twisted pair

Crimping a twisted pair or crimping is a process, during which the cable is cleaned from external insulation, straighten and veins are spinned, and then installed in the 8P8C connector (it is the same RJ45 connector) and clamp.

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

• on your Internet cable broke the connector;
• you decided to connect two computers to a wired local network;
• you need to connect the computer to the router through the cable;
• it is required to lengthen the wire through;
• and in many others.

Make an Internet wire crimping at home is easy, however, for the perfect result, some tools and components will be required, namely:

• twisted pair of the desired length;
• press clamp (crimper);
• one or two connectors (better to buy a lot of several pieces).

On the this moment Two types of cable crimping types are used. One of them is called a straight line, and the other cross (or cross-crimping). They differ in pinout lived in the connectivity and application in practice.

Direct Straight Crimping or "Computer Hub"

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

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

It is called "straight" because on both plugs of the wires of the conductors in the RH 45 will be located in the same order:

This type of pinout is used to connect with a data transfer rate up to 1 Gb / s. At home, most often STRAIGHT crimping is used to build a local network by fiber optic cable.

Since most providers offer tariffs at a rate of up to 100 Mbit / s, they use another wiring, in which only 1, 2, 3 and 6 veins are involved.

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

Always carefully examine the patch of the Court, which paves the provider.

If they use a two-party crimp, provided that you can overheat on all 4 pairs, the speeds will not be added to you, and the former with wriggling of all 8 wires will provide.

Cross Cross Cross or Computer Computer

Used to connect single type devices to each other, for example:

• computer - computer;
• router - Router;
• tV - computer.

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

With cross-burning, all 8 lived always, the figure shows a method that allows speed of up to 1 gigabit / s. If the equipment does not work with such throughput, the speed will be reduced.

Now, when it was possible to determine which patch cord needs to be used, they found out the necessary pickup and how many living way to apply, you can go to the process itself.

Using ticks

The most correct option when crimping the RJ-45 plug and twisted pair is to take advantage of special tongs.

In a professional language, they are called Crimper.

The name comes from the English word CRIMPER - to crimp.

Why it is necessary to crimp the ticks for crimping:

1. Convenience - have a comfortable form and so easy to use that everyone can use.
2. Saving time - collected all kinds of bustards, which will allow one tool to spend three procedures.
3. Safety - they cannot harm themselves, only if you specifically make a finger into cutting pads.

Everything is prepared, now proceed to compression.

For this you need:

1. To bite off the old connector, it can be used as a sample of the pinout lived. If not, then you can go to the next step.
2. Clean the veins from the outer shell. The length of the stripped wiring should be peeling the length of the connector or a little less, but not more. You need to measure the length from the cut edge and insert the wire into the zone for stripping. Now you should bother the cable, remove the outer shell from the ticks and remove the outer shell.
3. Colored veins, as we already know, inside the cable twisted. They need to be accurately unraveling and align. If their length varies, then it is necessary to shorten too long.
4. Without inserting into the connector, you must arrange the wiring in the sequence in which the crimp will be carried out.
5. Next, you need to insert veins in the connector. It should be inserted so that the part of the external patch climbs inside. In this case, the plug will be strong and the cable will not crash when used.
6. Next, it is necessary to accurately put the cable with the connector into the zone for crimping the power cable and firmly compress the handles of the crmper. During this movement, the knives of the ticks are squeezed by the connector terminals, which cut the insulation of the conductors and secure them in the connector.
7. The last step is to verify that the work is performed qualitatively. Stir the RJ 45 connector if no veins jumped out of their places and he did not disappear, it means that everything is fine.

Install the cord into the port and check the connection.If LAN light bulbs or Wan Port. they froze, Internet appeared or the desired device appeared on the network, the cable will be powder correctly.;

align the wiring length;

position the veins in accordance with the desired layout;

insert the wire into the RJ45 plug.

Next, you must check how the conductors got up. If the order is observed and each is in its path and concerns a golden terminal, go to crimp. You need to put the connector on the table so that the latch is from below. Take the hole and put on the mount in the connector, which will fix the cable itself in the connector.

After that, the same diverter, it is necessary to urge the terminals of the connectors on one one. It is necessary to do so that the contact of the terminal punched the insulation of the veins and became with the wire with one whole.

You need to perform this step particularly carefully and calculate the power at each press so as not to take the terminal and do not break the connector.

As soon as all 8 lived, it is necessary to check the work.

Make it can be done different waysDepending on what purpose crimp was made for what purposes.

If you have done a wire for connecting a computer with a router, connect one plug into the WAN connector on the router, and the second in Ethernet is the PC connector. With positive, the results of the light bulb "freeze" and you can set the Internet connection.

As practice shows, produce dIY repair Internet cable is completely easy. This procedure does not require any special knowledge, the main thing is to understand which wiring the lives will be used.

Otherwise, the case of the technology, you can crimp the Internet wire using a special crimp or limit to simple scolding. Of course, in the first version it is possible to make it faster. But the main chip of the second is to not buy a tool. The method is especially relevant for those who do not need to do this work constantly.

In many families, several devices are connected to the Internet: without a worldwide web We have no live life, because everyone needs its own line. They work, mainly on the wireless protocol - Wi-Fi, but the wire is still available, since so far wired Internet More stable than wireless. During the repair, all wires are hiding into the walls and "Internet" no exception. They are like electric, start on the sockets, only another standard: called computer or informational. They can be with different connectors, but the most common - rj 45. Installation and connection can be made independently, but since it looks unusual, wires in it more than two or three, and the connection is provided not to soldering and not twin, you need to know How to connect the Internet socket as well as the connector that should be inserted into it.

Criming Connector RJ-45

The Internet cable coming into the apartment or house, which is most often called twisted pair, often ends with a small plastic connector. This is the plastic device and there is a connector, and usually RJ45. On professional jargon, they are also called "Jack".

The case is transparent, thanks to which the wires of different colors are visible. The same devices are used on the connecting wires that are connected to computers with each other or with a modem. Only the order of the location can be different (or as the computer, pinouts) of the wires. The same connector is inserted into the computer socket. If you understand how to distribute in the connector, there will be no problems with connecting the Internet socket.

Internet cable connection circuit

There are two connection schemes: T568A and T568B. The first option - "A" in our country is practically not used, and everywhere the wires are positioned according to the "B" scheme. It must be remembered, since it is required in most cases.

To finally clarify all the questions, let us talk about the number of wires in twisted pair. This Internet cable is 2 pair and 4 pairs. To transfer data at a speed of up to 1 GB / s, 2 pair cables are used, from 1 to 10 GB / s - 4 pairs. In the apartments and private houses today, mostly streams up to 100 MB / s. But with the current pace of development of Internet technology it is quite possible that after a couple of years of speeds will be calculated by megabits. It is for this reason that it is better to immediately share a network of eight, and not from 4 conductors. Then, when changing the speed you do not have to redo anything. Just the equipment will use a larger number of conductors. The difference in the price of the cable is small, and sockets and connectors for the Internet are still used eight-pin.

If the network is already divorced by a two-party, use the same connectors, only after the first three conductors laid down according to the B scheme, you skip two contacts and the green conductor is placed in the sixth place (see photo).

Crimp twisted pairs in the connector

For crimping wires in the connector there are special ticks. They cost about $ 6-10 depending on the manufacturer. It is more convenient to work with them, although you can do the usual screwdriver and nippers.

First, insulation is removed from the twisted pair. It is removed at a distance of 7-8 cm from the end of the cable. Under it there are four pairs of conductors of different colors twisted in two. Sometimes there is also a subtle shielding wire, it simply flexing to the side - we do not need it. Couples are spinning, wires align, spreading in different directions. Then we fold according to the "B" scheme.

The order of sealing the RJ-45 connector in the connector

Wires in the desired order clamp between the large and index finger, posting the wiring smoothly, tightly to each other. Aligning everything, we take plumps and cut off the excess length of the wires posted in order: it should remain 10-12 mm. If you attach the connector as in the photo, the insulation of the twisted pair should begin above the latch.

Twisuate couple with cut-off wires in the connector. Please note that you need to take it with a latch (protrusion on the lid) down.

Each conductor should get into a special track. Insert the wires until you stop - they must reach the edge of the connector. Holding the cable at the edge of the connector, it is inserted into the ticks. Tick \u200b\u200bhandles reduced smoothly together. If the housing has become normal, no special effort required. If you feel that "does not go" to recheck if RJ45 is right in the nest correctly. If everything is fine, try again.

Under pressure, the protrusions available in the ticks move the conductors to Micronozham, which will shift the protective shell and provide contact.

Such a connection is reliable and problems with it rarely occur. And if it happens, rebuild the cable easily: cut off and repeat the process with another "Jack".

Video lesson: crimping connector RJ-45 toll and screwdriver

The procedure is easy to repeat it. Perhaps you will be easier to do everything after the video. It shows how to work by ticks, as well as how to do without them, but to do everything with the help of a conventional direct screwdriver.

How to connect the Internet cable to the outlet

Now they reached directly before connecting the Internet socket. Let's start with varieties. As well as ordinary electrical outlets, informational are two modifications:

By the number of points, the connection is single and double computer sockets.

At least externally, computer sockets differ, the principle of connecting conductors they are the same. There are special contacts equipped with micronjam. The inserted conductor cuts the protective shell. As a result, the metal of contacts-microscheus fits tightly to the metal of the conductor.

How to connect a wall computer socket

Inside each socket there is a hint on how to place the wires when connecting the Internet cable. Manufacturers glue the color scheme that we have seen when the connector is burning. There are also two options - "A" and "B", and we also use the option "B".

The housing is attached to the wall, as a rule, the inlet hole for the cable up, the computer connector down. Next, the actions are simple:

Connecting a twisted pair to a rosette is really an easy procedure. Even for the first time she will take a few minutes. Once again, see what you can do in the video. It first shows the connection of the Internet cable with 4 wires, then - from 8.

How to connect an internal online outlet

Installation of a plastic box will not describe - this is another topic. We'll figure it out in the features of the connection and assembly. The main snag here is how to disassemble computer sockets. When the conductors are connected to them, it is necessary to get to the contact part: a small ceramic or plastic housing with mounted micronjam contacts. The conductors are connected to this mounting plate, and then the case is collected again. And the whole problem is that from different manufacturers they are going / disassembled in different ways.

For example, a popular manufacturer computer sockets Legrand (LEGRAND) To get to the connectors in the LEGRAND VALENA RJ45 computer socket, you must remove the facial cover. The white plastic impeller will be found under it (as in the photo) on which the arrow is applied.

It is necessary to turn the impeller in the arrow, after which you will remain in your hands the housing and contact plate. It applies color marking of conductors. The connection is no different, except that - first in the hole on the plate you need to turn the vita pair, and then breed the wires.

For clarity, look at the video.

Another popular manufacturer of such equipment is Lezard (Lesard). He has another system. The facial panel and metal frame are fixed on small bolts. It is easy to unscrewed, but the inner contact plate holds everything on the clips. Collecting and analyzing the LEZARD computer sockets (Lesard) in the right places it is necessary to press the contacts with a screwdriver.

To remove the plastic contact group from the housing, it is necessary to press on the latch located on top. After that, in your hands you will have a small box. But that's not all. It is necessary to remove the plastic lid, which closes and presses the conductors. Remove it up with a screwdriver lateral petals. Plastic elastic and effort is pretty pretty. Just do not overdo: it is still plastic. After that, wire wiring is standard: according to the sides of the markup (do not forget that we use the "B" scheme).

If you know how to connect the Internet socket, even with an unfamiliar model understand easy. And you can now upgrade your network yourself (increase the length of the twisted pair, transfer the computer to another place, make another point of connection, etc.), without attracting specialists. Another question remained: how to connect double sockets. Two cables are added to them and further flows on the color scheme. This is possible when the network is generated by a modem or two Internet lines come. Is it possible to solve both entrances with one cable? It is possible, but you need to not get confused in the color designation of the wires in the further wiring of the network (remember which color instead you used).

With the advent of the Internet, the lives of many families changed. Most of them are connected to the Internet, especially since it is not necessary for this much, it is enough to have personal Computer or the most common mobile phone. In turn, each family member can be connected to a separate line. Local distribution of the Internet resource is carried out wireless way by special Wi-Fi Protocol. And yet, many prefer distribution by wires, as it is much more reliable, easier and cheaper. In addition, the presence of additional electromagnetic waves adversely affects human well-being.

As a rule, all wires try to hide into the walls so that they do not interfere. Internet wires are no exception. These are mainly carried out during the repair work. For this exist special sockets, called computer or information. Basically, outlets are used with RJ-45 connectors. All processes for its installation can be done by himself, if you know how to do it, especially since the wires can be more than two and you need to know what kind of contact which is connected. The procedure is performed not twice and not soldering, but by the help of crimping, applying a special tool for this.

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

Basically, the plastic connector is made of transparent material, through which all multicolored wires are visible. Absolutely the same details are used to connect computers, a modem with a computer and another computer "iron". In this case, it is possible not the usual location of color wires. This connector is inserted into the information socket. Here the most important thing is to deal with the order of all wires and then the problem with crimping the connector will be solved.

There are two connection schemes: T568A and T568B. We are not practiced the first connection option, and the connection is carried out according to the "B" scheme. Therefore, you need to get acquainted with the location of colors, according to this scheme.

Highly important moment - This is the number of wires in twisted pair. As a rule, cables with 2 pair or 4 pairwise wires are used. 2 Paired cables are used to transmit data at a speed of up to 1 GB / s, and 4 paired - for data transmission at a speed of 1 to 10 GB / s. In private houses and apartments have an Internet wire, where data transmission is carried out at a speed of up to 100 MB / s. Despite this, there is a steady trend towards an increase in the transfer rate of Internet resources. Therefore, it is better to reinforce and install the 4-paired cable with the expectation for the future. Moreover, the connectors and sockets are manufactured under the connection of the 4-pair twisted pair.

When using a 2 paired cable, after laying the first 3 wiring according to the "B" scheme, the green wiring is connected to the sixth contact, skipping two contacts. This can be seen on the appropriate photo.

To enhance the ends on the connector, special ticks are used, which can cost from 6 to 10 dollars, depending on the manufacturer's company. When applying a similar tool, high-quality contacts are obtained, although it can be done using bruises and screwdrivers.

To begin with the cable, you need to remove the protective insulation, at a distance of 7-8 cm from the end of the cable. In the cable there are four pairs of wires of different colors, twisted pairwise. There are cables where there is a subtle shielding braid. She will not need it, so it can be simply bent to the side. All pairs are spinned, and the wires are aligned, bred to the sides and laid out according to the "B" scheme.

Divorced wires are clamped between large and index fingers. With this, you need to control the wires to be smooth and tightly pressed one to another. If the wires have different lengths, they can be aligned with nipples, leaving a total of 10-12 mm long. If you take a connector and try, the insulation of the wires should begin slightly above the latch.

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

It is very important that each wire gets into a special track, while each wire must continue to the edge of the connector. Holding the cable in this position, it is inserted into the ticks. Crush the cable smooth, careful motion as long as the tick handles do not comply with. If all prepared operations are made correctly, no problems should be. If it is felt that an additional effort is necessary, then it is desirable to suspend the crimping process and check everything again. The main thing is that the connector takes the right position. After checking and adjusting the crimping continues.

In the process of crimping, the ticks push the conductors to micronozham, which are insulated and installed contact with the conductor.

As a result, a reliable connection with excellent contact is obtained. If it did not work from the first time, the crimping process must be repeated. For this, the wires with the "Jack" are cut off, cleaned, the new "Jack" is taken and the process is repeated. The main thing is to stock "Jacks", because from the first time it is hardly possible.

Video lesson: crimping connector RJ-45

Thanks to the emergence of the Internet, many problems are solved fast enough, especially after the revision of the videos. Therefore, before proceeding directly to the burning of the wires, it is advisable to revise the video, and very carefully. It shows how you need to properly handle the ticks and how can you do without them. And yet, it is better to be restrained and use the tool for better work.

How to connect the Internet cable to the outlet

To begin, it should be noted that Internet sockets, as well as the power out of two types, there are two types: for outdoor installation and for internal installation.

It should be noted that all the outlets are collapsible and consist of three parts: half the housing of the socket is used for fastening, the internal sockets are designed to connect wires and the second part of the case as a protective element. There are both single and double online sockets.

Computer sockets may vary appearanceBut the principle of work they have the same. All are equipped with contacts with micronjam. As a rule, they are designed to cut the insulation of conductors, after which reliable contact is installed, since the process is carried out under a certain amplification.

Connecting a wall computer socket

Almost all manufacturers of computer sockets are placed inside the connection scheme, with the designation of the procedure for placing the wires, based on their colors. As a rule, the scheme "A" and the scheme "B" is also indicated. The scheme "A" should not be taken into account, but focus on the "B" scheme.

First, it is started to install the housing on the wall, placing it so that the input hole for the cable look up, and the computer connector is down. Although this installation option can be changed, depending on the specific conditions and the socket can be installed horizontally.

As can be seen, the connection of the Internet socket is not a challenging operation and anyone can cope with it. It can take just a few minutes. In this case, it is enough once, although for the first time it may not work, especially if there are no skills to handle the wires.

To do not particularly suffer, it is better to watch the corresponding video, where it is shown and describes how to connect a computer socket with 4 wires and with 8 wires.

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

Connecting an internal online outlet

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

The most important thing is to disassemble it so that it is free access to contacts with micronjam. It is in this part that a connection is carried out, after which the cover of the housing with the contacts is closed. Each model of such a socket has its own way of assembling and disassembly.

If you take, for example, a LEGRAND computer outlet, then to get to the location of the wires of the LEGRAND Valena RJ-45 socket, it is necessary to start removing the front cover. Inside the case, you can see a white plastic panel with an impeller, where the arrow is drawn (see photo).

The handle on the panel rotates in the direction of the arrow, after which the front panel is removed. There is a metal plate with a pattern on the surface of the panel, which can be defined to which contacts and which wire should be connected. The color marking of twisted pairs is also indicated here. Before the start of the connection, in the hole located on the plate, the wires prepared for the connection process are taught.

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

You can find and a socket for connecting the Internet of the company LEZARD. Here the design is completely different. The front panel is designed on the screws, so to remove it, it is enough to unscrew these screws. As for her indoors, everything is fixed here on latches. To pull out of the housing of the inside, you need to take the usual, small screwdriver and squeeze clips.

To get to the contact group and remove it from the body, you need to click on the latch, which can be detected from above. As a result of such actions, a box can be in hand with which you will have to remove the lid to get to contacts. To remove the lid, it is enough to make a thin object side petals. We still have to make certain efforts, since the latch is quite elastic. At the same time, you need to remember that in the hands of plastic and, if everything is not neat, then you can break.

For greater clarity, it is invited to familiarize yourself with the video lesson.

In conclusion, it is worth noting that the existence on the Internet the relevant video simplifies the process of mastering various actions or carrying out works associated with connecting computer sockets. Despite the fact that every model of the socket is arranged in its own way, 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 a twist or soldering, which would be available to almost everyone. But at the same time, it would not be possible to provide compactness and accuracy of the connection itself. But in such connections there are its advantages: I would not have to stock up "Jacks". Although on the other hand, such a connection method is more designed for professionalism, simplicity and speed, especially if you use a special tool.

And, nevertheless, if there are at least some skills of working with electrical pipelines, then this connection does not contain any difficulties. I did not invite any specialists, really make a wiring of a computer network in your apartment or a private house. Moreover, such experts will take a considerable amount for this.

Most often, the installation and connection of the Internet socket relating to low-current lines is made in the triple block:

• Normal 220 volts

• Internet socket

• television

Most models, such as Schneider Electric (Unica series), Legrand, Lezard, the installation principle is almost the same and does not contain cardinal differences.

Step by step. Consider the entire cycle connecting the Internet socket.

Internet cable

Installation begins with installation in a low-current shield of the router and connecting it from a 220V power outlet.

Next, in a separate cable channel or a strobe that is not associated with the power lines, the 4-paired UTP series 5e is paired.

Such a cable provides a connection speed to 1 gigabit per second at a distance of up to 100m. Here is its technical characteristics:

There are shielded and not shielded varieties. Foil as a screen performs on networks where there is a normal grounding.

One such cable is 5e (4 pairs), you can connect only two outlets. In this case, 2 pairs will be involved separately.

Installation is carried out by a solid wire directly from the shield to the opposite. Create the cable to the mounting box and leave the necessary reserve - from 15 cm and more.

Montage online sockets

From the socket, you first remove the lining and pull out the caliper for the convenience of installation.

If the design of the socket allows, the frame on the peavern can be mounted initially. Thanks to the groove in the frame, you can easily adjust the horizontal location.

3 * 25mm screws pre-tighten the entire design. At the same time, the Pocket Electric level is checking the installation accuracy and tighten the screws finally.

Manufacturers B. lately They began to perform the frames of the aluminum alloy, they are of course stronger in design, but they will not be magazine to the level. We will have to keep it with one hand on weight.

Next, we biteate and leave the wire supply in the riser, a maximum length of 15 cm. Remove the top layer of isolation from the UTP cable.

For removal isolation, so as not to damage the veins, it is better to use a special tool - stripper. But you can do all this neatly and ordinary stationery knife.

The top layer from the cable must be cleaned for a length of no more than 2.5 cm. Cut off the thread unnecessary in this case, which goes between the veins.

A strong thread in cables with a twisted pair is often used to facilitate the opening of the shell on a long length. It is even so called - the discontinuous thread. In the telephone cables it is separated by bundles and oops.

Slightly depart separately alkali. Next, pull out the inside of the socket with contacts.

As a rule, to any brand, whether TV, the Internet socket or the usual 220 volts must go instructions.

Instructions for Legrand -

Standards and Connection Scheme

Open the cover of the contact part and carefully study the label. Each RJ45 outlet can be connected in two ways:

• According to the standard "A"

• According to the standard "B"

In most cases, the second option is used - "B". To understand where what wires are connected, carefully inspect the case. It should be depicted which standard corresponds to certain contacts.

For example on Unica:

• The protocol "B" refers to the upper color label. When connected, you will focus on these colors.

• "A" - to the bottom color marking

If they figured out this, then with further installation there will be no difficulties. The "B" protocol corresponds to the color scheme according to EIA / TIA-568B standard. On one side of the clamp should be the following colors:

• white orange

• orange

• white green

• green

On the other side:

• blue

• white blue

• white brown

• brown

Move the wire through the lid. In this case, as mentioned above, the top layer of the UTP cable isolation should not be removed, more than 2.5 cm.

It is impossible to clean it under the very wall of the opposition, as they make with ordinary NYM or WGN cables.

Cut without insulation should be minimal length. All these oblasts are made not with simple. Their exact amount per 1 meter cable is strictly calculated and regulated.

Otherwise, if you have improper connection and stripping, you may have no speed, but also the quality of data transfer.

Next, insert all the wires into contact grooves in colors.

After that, just snap the lid. Extra segments lived, which protrude out it is necessary to cut down after closing the lid.

The socket is actually already connected. It remains to insert it into place in the caliper.

The main advantage of such online sockets is that they do not need to remove insulation with them at all and slander it before copper. Inside the socket itself already installed special knives.

When you slam the cover, the knives automatically cut through the insulation and the contact compound is formed. In the instructions such stamps often indicate that when the wire is connected, the use of special crossover crimping is prohibited.

It seems to be in the design. That is, when the lid closes, it slices the insulation itself and lays the wires to the desired depth of the connector.

Connect to the router and connotor crimping

After mounting the Internet socket itself, it remains to correctly connect the cable to the router in the communication shield.

Remove isolation from the other end of the cable by 2-3cm. The veins are flushing and insert in a certain order, according to the TIA-568B standard, or simply "b".

The location of colors is considered to be left:

• white orange

• orange

• white green

• blue

• white blue

• green

• white brown

• brown

Standard "A" is sometimes used if you need to connect one computer with another. Here one end of the cable contract according to the "B" standard, and the other by "A". In general, if both ends of the cable are compressed according to one standard (AA or BB), it is called patch cord. And if they are changed in places (AB or BA), then - Cross.

Veins again do not need to clean. Just insert them into the connector until it stops.

After that, all this is pressed by a special crimper. Some make a thin screwdriver or blade a knife, though you can easily damage the connector.

Cat5E cable and Cat6 in the RJ45 connector are crimped according to one principle. Another "plug" is not required here. Differences in cables in data transfer rates, Cat6 is more.

Internet connection check

After installing the Internet socket and connector on the other end of the cable, it is desirable to check the connection and integrity of all connections. You can make it the cheapest Chinese device.

What is his essence? There is a signal generator that submits pulses by specific codes, and receiver. The generator is connected to the router installation site, and the receiver directly into the socket itself.

After the pulse is supplied, the signals are compared. If everything is fine, alternately light green lED bulbs On the receiver case. If somewhere a break or short circuit, then one or more light bulbs will not burn at all.

When this happened, first of all you need to sin on bad contact in the connectors. Most often, it is there, on any dwell, isolation is not completely cut off and there will be no compound accordingly.

At the very end, the finished proven cable with the connector connects to the router.

How to connect 4-core telephone cable

And what if you have a 4-wire telephone cable for the Internet, and the socket under the standard 8 lived? How to connect the scheme in this case?

A simple color connection here does not help. That is, if you have a white-blue inhibit in contact with white-blue marking and in the color of the coloring, connect all other veins, there will be no signal.

This is explained by the fact that to transmit the signal to use contacts 1-2-3-6.

On the one hand, two veins start 1-2:

green \u003d. bluelived

In this case, everything should work without problems. Just remember that here the most important thing is not color, namely position. Colors are used in order to be visually easier to distinguish between the positions of the same veins at different ends of the cable.

Also keep in mind that when using 4 wires, i.e. Two pairs of twisted pair, you can reach speeds up to 100 Mbps / sec. But for a gigabit network (1Gbit / s), all 8 wires will be needed.

Errors when connecting the Internet socket

1 Incorrect connection lived according to the protocol.

You can easily confuse the order of the location of the veins on the connector and in the rosette itself. Roughly speaking to flip them over 180 degrees.

Here, everything is checked by a more careful study of the inscriptions on the housing of the socket and the colors themselves lived. Tester with generator and signal receiver Good assistant to identify such errors.

With incorrectly opening, lived, the light bulb on the tester will not light up in order from 1 to 8, but in arbitrary versions. For example, first 1, then at once 3, then 2, etc.

2 Not significant, but still the error is considered if the veins from the contact plates of the socket are not cut off after the cover is closed, and up to this point.

That is, immediately after laying them in their places in the slot. In this case, there could be accidentally falling, and inserting it back cut off will no longer succeed. We will have to re-inspire everything and pass the entire connection cycle on a new one.

And if you left the cable stock in the mounting box small, then you will come to the big headache at all.

3 Stripping external isolation on a large distance, up to the walls of the opposition, as in conventional networks 220V.

As mentioned earlier, here is the result - deterioration of the speed and quality of the signal. Moreover, you do not need twisted pairs to break up to the place of insulation, the more screwdriver. Just expand their lifting the veins on the required length to start in the slot.

According to the standard, no twisted pair is allowed on more than 13mmotherwise in tests frequency characteristics Crosstalk errors will appear. In practice, problems will begin when loading the network of traffic.

A task: To combine computers in the network you need wires. Network cord (Ethernet - cable) is freely sold and called Patchcord. If you need a patchcord longer or vice versa - shorter, you can make it yourself.

Instruments: For the manufacture we need:

1. Cable "Twisted Pair", also called UTP ( Unshieded Twisted Pair - Unprotected Twisted Couple). The cost is usually about a quarter of a dollar per meter. Also for sale in 305 meters bays. The bays are naturally cheaper. There is still a protected twisted pair (FTP Foild Twisted Pair). Usually more expensive due to braid, which shields cable. For home use need not. Cables are broken by category. For the house, the 5th category is enough. In catalogs and stores, it is designated: UTP Cat5.Sometimes to save providers to pull cable with 2 AApara, instead of 4. For such cables, the speed will be limited to 100 MB / s. How to crimp the cable twisted pair with four wires (two pairs) - read below.

2. Connector (Can also be called "Jack", "connector") RJ-45. 2 on the wire + 1 is often spoiled :) Take the reserve.

3. Tool for crimping. ("Swage"). Special pliers for crimping connectors. An indispensable tool. Without it, it will not work well. Look for friends, acquaintances, ask Adinistors, they have sure. With a certain skill, you can scratch the connector with a knife, but this occupation is rather for extremes and the quality here does not have to wait.

Let's start.

1. Crimp ticks cut insulation by approximately 3 cm. From the end. In the ticks usually there is a semicircular recess with a knife from above. Put in the recess cable, clamp the knife on top and wrap the pliers around. Isolation will steal.

2. Check if you accidentally cut some wire when the isolation was cut off. If the wire was cut, they were thrown or tear off - it is necessary to start all over again. Boldly bite off a spoiled piece of cable and start all over again.

3. Disassemble wires by colors. Split them well at the base, spread them in color order.

3.1. Crop the wires in twisted pair need to be strictly defined. The most popular scheme is as follows:

B-op, op, b-beer, blue, b lying, green, b-kor, cor.

It is necessary to crimp from both ends the same. In this case, we will succeed. Direct cable. For cross-cable, the scheme at different ends is different: on the one hand standard:

B-op, op, b-green, blue, b lying, green, b-cor.,

with another: B-beer, green, b-op, blue, b lying, op, b-kor, cor.

3.2. If there are 8 wires in the cable, and 4, then the order of crimping will be different.

If you need to enhance the cable from both sides - do according to such a scheme

1: White-orange
2: Orange
3: White-green
4: Empty
5: Empty
6: Green
7: Empty
8: Empty

(instead of green can be blue)

If you need to enhance only one end of the cable, and the second will already be enjoyed - it is better to see how the second is cured and do the same.

4. Lay out the wires in order, align and flexing, flexing them all together achieve that wiring will be tight to each other pressed.

5. Sweep the edge of the wires as much as possible. Leave approximately 1.5 cm.

6. Gently so as not to break the folded wires insert them into the connector. Odja Connector Make sure that the removal at the bottom of the connector captures isolation. When burning, the excavation is pressed and fixes the connector on the insulation.

7. Turning the end connector make sure that all the wiring reached the edge of the connector and are visible there. Metal knives that are pressed into the wire must capture it entirely.

8. At the same time, the pushing wire towards the connector compress the ticks.

9. Making sure that the colors are not confused. Hold the connector is finally. After crimping the second end, check the performance. With unsure work, boldly cut off and crimp again.
