The Internet today occupies such a role in our lives that now it is practically impossible to find a place where there would be no possibility of connecting to the network. Whether it is a metropolis or a remote village, the Internet takes its place in homes and in the lives of their inhabitants. Almost all modern appliances have the ability to connect, and no one is surprised by an interactive refrigerator or TV. Therefore, installing and connecting sockets for wired Internet is a very relevant topic, and if you have not yet encountered this task, then it is likely that sooner or later this will happen. You can call a wizard from your provider's staff to RJ-45 socket installation, although you can do this work yourself if you wish. Low voltage currents flow in the wires for connecting to the Internet, and when you connect an RJ-45 socket, you can not be afraid of electric shock. If you decide to do the job without resorting to help, this article with a video will help you with this.
The RJ-45 network socket is a standard product, depending on the manufacturer, differing only in appearance. When wondering how many sockets for the phone and how many for the Internet to install, you can not hesitate to install an RJ-45 socket for connecting to the Internet, since you can connect a telephone wire to it and connect a phone.
RJ-45 socket wiring diagram
The wiring diagram for an RJ-45 socket is not particularly difficult. Having removed the outer insulation from the cable by two to three centimeters, we unwind 4 paired cores and clean them of insulation, preferably with a special knife ( stripper). We open the case for the internal connection of the RJ-45 socket. We see that all contacts are highlighted in a certain color corresponding to the desired wire so that it will be difficult to make a mistake. It is necessary to clean the wires in such a way that the wire coming out of the case is covered with external insulation, and the bare part is only at the point of contact with the latch. In network sockets for connecting RJ-45 Legrand, it is not necessary to clean the insulation from twisted pairs.
The contacts of these sockets themselves pierce the protective sheath of the wire. Models of these brands have proven themselves to be reliable, beautiful and easy to connect. RJ-45 socket pin latches work to hold, and you just need to attach the appropriate wire to them and press it from above with a knife or thin screwdriver, or close the special clip provided in some socket models. After making sure that the contacts securely hold the wires at all points, we insert the socket into the socket in the wall and tighten the fixing bolts until the socket is held in the desired position. Screw or put on the top cover. If the network wire is connected to the station, the RJ-45 socket can be immediately used for its intended purpose. The wire from the station must be removed into the wall or into a special wire channel.
In some cases, it makes sense to connect a double RJ-45 socket, since each computer needs its own port to connect to the network. The principle of connection and installation is the same.
Most people live in separate apartments and private properties. And often for each room it is necessary to solve one small, but rather insidious problem: in an affordable, low-cost, but effective way to create an access point for connecting to the Internet. It would seem that the answer is obvious - purchase, configure a Wi-Fi router and forget about all the problems. However, wired Internet still remains the most common and reliable solution, because such a signal is much more stable. This leads to another problem - how to hide the Internet wiring? Usually it is mounted on walls and plugged into sockets, although not of a completely standard type: they are called computer or simply Internet sockets.
What is an internet socket
The main difference between an Internet outlet and a conventional electrical outlet is that it has its own unique connector, to which a special type of wiring called twisted pair is suitable. It is unique in that it contains 8 individual copper wires twisted together in 4 pairs. Thanks to such a connection system, existing electromagnetic interference is leveled, which ultimately ensures a high data transfer rate (up to 1000 Mbps).
The Internet socket has a special connector to which a twisted pair cable is connected.
The return connector is called RJ-45/8p8c. It is mounted on the cable using a special tool, and the connector wires must be arranged in a strictly defined order.
The sequence of colors of wires connected to the pins of the connectors is determined by the standard scheme
Classification of Internet outlets
IT specialists classify Internet sockets according to their distinctive features:
Algorithm for laying an Internet cable in the walls
The most correct, but at the same time, the most difficult solution for laying an Internet cable in a home (office) environment is its installation inside the walls. The advantages of such wiring are obvious: the cable does not get under your feet and does not affect the decorative design of the room. A significant disadvantage of in-wall installation is that in the future there may be problems with access to the cable for its repair or maintenance. But with proper cabling along the strobes in a corrugated PVC pipe, you can not only minimize the risk of a malfunction, but also provide relatively easy access to the twisted pair without complicated dismantling.
Before you start laying an Internet cable, it is worth marking the places where it should be located. Remember that unshielded twisted pair is made of copper, which is very sensitive to electromagnetic interference. Try to keep the distance between computer and electrical wiring at least 50 cm.
How to pinout an RJ-45 cable
When crimping a twisted pair, it is necessary to adhere to a certain pinout (color scheme). There are two generally accepted connection standards.
To select the correct connection color scheme, you should contact your Internet service provider and get information from him about which scheme was used during the connection.
We perform the work in the following order.

Connecting RJ-45 wire to two twisted pairs
A two-pair RJ-45 cable uses data rates up to 1 Gb/s.
The two-pair cable is connected to one side of the socket contacts.
The pinout of a two-pair cable is made in the same way as a four-pair cable. Only instead of eight multi-colored wires, only four are switched: white-blue, blue, white-orange and orange. Then the cable is crimped, the socket is assembled and installed and its performance is checked.

How to crimp an RJ-45 cable on the pins of an Internet outlet
When pinning the cable to the terminals of the Internet outlet, they should be crimped. This will affect the performance of your internet connection. Based on a similar process for conventional electrical outlets, one would assume that crimping an Internet outlet is a similarly time-consuming process, removing the protection from each individual wire and then connecting them with bolts. In fact, everything is much simpler and faster. At the Internet cable, the contacts are arranged in such a way that when the conductor is firmly connected to them, they cut the insulating coating, due to which they come into contact with the copper core. Because of this, stripping each wiring is not necessary.
Usually, an extractor is used to crimp socket contacts - a crossover knife. Work should be done carefully to avoid damaging the cable.

Signal verification, testing
After pinning out the Internet outlet and the RJ-45 connector at the opposite end of the cable, you should make sure that the line is working. Testing is best done with a special device called a cable tester.
It is better to check the performance of the outlet with a specialized device.
It consists of two parts - a signal generator that transmits short electrical impulses using encrypted codes, and a receiver that processes these codes. The generator connects to your router and the receiver connects to an internet outlet.
After the transmission of electrical signals, they are compared. If all connections are in order, two green LEDs on the generator and receiver housings light up sequentially. If there is a break somewhere on the cable or there is a short circuit on the Internet outlet itself, then one or both LEDs will not light at all.
Overview of products of well-known brands - manufacturers of Internet outlets
Without exception, all Internet outlets are divided into two large subgroups: mortise and outdoor. The manufacturer usually only slightly changes the mechanism for attaching the outlet to the wall, but the principle of connecting it to the Internet always remains the same. Consider the most common brands of manufacturers.
Legrand ("Legrand")
Internet sockets from the French manufacturer are not only among the most popular, but also have one of the best cable retention mechanisms. The wiring diagram for Legrand sockets does not differ from generally accepted standards. At the same time, any Internet socket can be connected both according to type A and type B. The color schemes for connecting are located on the terminal of the socket itself.
The pinout and connection of the Legrand socket is made according to the generally accepted scheme.

Viko ("Viko")
Viko sockets are cheaper than Legrand ones, while their quality remains at a high level. The case is made of durable polymer materials, and the internal assembly is very ergonomic.
Viko sockets are an economical and high quality solution
The only major difference from other manufacturers is that inside the terminal there are no hints in the form of a color scheme for connecting. Therefore, the pinout should be done very carefully.

Lezard ("Lezard")
Lezard brand switches and sockets are produced by the Turkish company Dernek GROUP. They do not have any distinguishing features.
Connecting and mounting the Lezard socket is quite simple.

Schneider ("Schneider")
This socket is connected by analogy with others. Often it can be double, then you have to run two cables from the router, since parallel connection is not supported by network equipment.
The most common version of the Schneider socket has two outputs.

Connecting the Internet network via cable is the most common way today. Wired Internet is still considered the most stable. For the convenience of connecting it, there are special sockets, thanks to which any cable can be hidden in the wall. Such a seemingly time-consuming task of connection and installation is actually solved relatively easily, without requiring the use of an expensive tool. Therefore, anyone can connect an Internet outlet.
According to the EIA / TIA-568 specification, there are several color schemes for crimping a twisted pair network cable (patch cord) into an RJ-45 connector for connecting a computer to a router, hub, switch, or connecting two computers to each other.
The network plug is usually called RJ-45, although its correct name is 8P8C. And RJ (Registered Jack) is the name of a standard that describes the design of a plug-in connection between a plug and a socket.
All the photographs below show one split utp cable designed for use in LAN (Local Area Network) and DSL (Digital Subscriber Line) networks, with twisted pairs crimped at its ends into RJ-45 plugs.
RJ-45 crimping color scheme computer - hub for the Internet
option B, the most common option.
Twisted pair lan cable crimp color code by option A.
As you can see in the photo, in both versions, the ends of the lan cable are crimped according to the same electrical circuit, only two twisted pairs are swapped. A green twisted pair is crimped in place of the orange twisted pair, and orange is crimped in place of the green twisted pair.
Twisted pairs of utp cables, crimped both in option A and option B, interchangeable. So you can compress according to any color scheme option that you like best, this will not affect the performance of the lan network.
Color scheme for crimping RJ-45 two-pair twisted-pair cable
Currently, a twisted pair network cable has appeared on sale, in which instead of the traditional four there are only two twisted pairs. And this is economically justified, since 90% of cable lines for the Internet use only two twisted pairs.
As you can see, the electrical circuit for connecting the RJ-45 pins has not changed, only the blue one is crimped instead of the green pair.
Such a twisted-pair cable according to option B is crimped according to the scheme shown above in the photo. When crimping option A, the pairs are simply swapped. Instead of an orange pair, a blue one is crimped, and instead of a blue one, an orange one.
RJ-45 crimping color scheme Computer - computer
If you need to create a local lan network of two or more computers without using additional active equipment (hub, switch or router), for example, for group games, then for this case the EIA / TIA specification provides for the following twisted-pair network cable cutting. To create a network of two computers, it is enough to insert one such twisted-pair cable into their network ports.
Please note that the opposite ends of the computer-to-computer twisted-pair lan cable are crimped according to different color schemes.
RJ-45 twisted pairs are crimped with a tool called a crimping tool. If there are no pliers at hand, then you can use twisted pair crimping technology without pliers.
All of the above color schemes for utp twisted pair cable pinouts are currently out of date. Modern network cards, switches, hubs and routers, thanks to the support of Auto-MDIX technology, automatically determine the twisted-pair cable crimping option and perform internal adjustments. So a modern computer, when creating a network, can be connected at least to a hub, or to another computer without thinking about the color scheme for twisted pair cable pinouts.

PoE IEEE 802.3af and IEEE 802.3at
The PoE IEEE 802.3af standard provides for the possibility of transmitting an information signal and supplying power to the device over a single twisted pair cable crimped with an RJ-45 connector. This eliminates the need for an additional wire for supplying voltage.
Regardless of the RJ-45 crimping options, from the positive output of the power supply, voltage is applied simultaneously to pins 4 and 5 (blue pair), and the negative output to pins 7 and 8 (brown pair).
As a rule, twisted-pair cable pinout according to the PoE IEEE 802.3af standard is used when creating video surveillance systems that use a switch, for example, a 9-port PoE switch ROKA R-KM-POE0801, in which each port has the ability to feed through RJ-45 DC voltage 12 V power up to 30 W.
RJ-45 Crimp Color Scheme 4 Wires for Internet
When connecting a computer to the Internet or creating a local network, rarely does anyone use the full capabilities of a twisted-pair lan cable. This is usually due to a lack of information.
When transmitting a signal over twisted pairs of a CAT5 cable (speed up to 100 Mbps), only two pairs of wires out of the four available in the cable are involved. One pair for signal reception, the second for transmission, which is clearly demonstrated by the above electrical diagram of connecting a computer network card with a twisted pair cable with an RJ-45 connector to a switch hub or router.
As can be seen from the diagram, each of the two pairs of lan cables is connected to a computer and a switch hub or router using a transformer symmetrical circuit. The advantage of the transformer circuit is the suppression of interference and interference and provide a high degree of protection against short circuits and errors when installed in a twisted pair cable.
If it becomes necessary to lay an additional line or if the pairs in the twisted pair network cable are partially damaged, it is possible, without degrading the data transfer rate, to double the number of lines or repair the twisted pair cable by crimping the RJ-45 plugs to previously unused twisted pairs.
The RJ-45 twisted pair cable crimp color schemes below are the same as above, but only show the lan conductors of the twisted pair cable that are used to carry information. Twisted pairs that do not fit close to the RJ45 plug are usually crimped, but the signal is not transmitted over them and they can be used to transmit additional information.

Twisted-pair crimping, option B. The signal is transmitted only on orange and green pairs.
Twisted pair crimping, option A. The signal is also transmitted only over green and orange pairs, but the twisted pairs are crimped in the RJ-45 plug to other contacts.

What is the difference between a patch cord and a twisted pair cable
A patch cord, or as it is also called a patch cord, is designed to connect electronic devices to each other, for example, a computer with a hub, a switch, or two computers to each other if the devices need to be moved relative to each other during operation.
For the manufacture of a patch cord, a twisted pair cable is taken, the cores in which are made of stranded wire so that they do not break with frequent kinks. For crimping such a cable, special RJ-45 connectors are used. According to the ANSI EIA TIA 568B.1 standard, the length of the patch cord must not exceed five meters. Connecting devices using a patch cord is economically feasible if they often move relative to each other during operation.

How to properly connect the Internet cable to the outlet. Wiring diagram for RJ 45
Most often, the installation and connection of an Internet outlet related to low-voltage lines is carried out in a triple block:
- conventional 220 Volt
- internet socket
- TV under TV
For most models, for example, from Schneider Electric (Unica series), Legrand, Lezard, the installation principle is almost the same and does not contain fundamental differences.
Let's take a step-by-step look at the entire cycle of connecting an Internet outlet.
Internet cable
Installation begins with the installation of a router in a low-current shield and connecting it from a 220V power outlet. 
Further, a 4-pair 5E series UTP cable is laid in a separate cable channel or gate not connected to power lines. 
This cable provides a connection speed of up to 1 Gigabit per second at a distance of up to 100m. Here are its specifications: 
There are shielded and non-shielded varieties. The foil acts as a screen in networks where there is normal grounding. 
On one such cable 5E (4 pairs), you can connect only two sockets. In this case, 2 pairs will be separately involved.
Installation is carried out with a solid wire directly from the shield to the socket. Run the cable into the junction box and leave the necessary margin - from 15cm or more. 
Internet socket installation
From the outlet, first remove the cover and pull out the caliper for ease of installation. 
If the design of the outlet allows, the frame on the socket can be mounted initially. Thanks to the grooves in the frame, you can easily adjust the horizontal position of its location.
With screws 3 * 25mm, pre-tighten the entire structure. At the same time, check the accuracy of the installation with the level of the Pocket Electric electrician and tighten the screws completely.
Manufacturers have recently begun to make aluminum alloy frames, they are certainly stronger in design, but they will not be magnetized to the level. You will have to support it with one hand on weight. 
Next, bite off and leave a supply of wire in the socket, a maximum length of 15cm. Remove the top layer of insulation from the UTP cable. 
To remove the insulation, so as not to damage the cores, it is better to use a special tool - a stripper. But you can do all this neatly and with an ordinary clerical knife.
The top layer from the cable must be cleaned to a length of no more than 2.5 cm. Cut off the excess thread in this case, which goes between the cores. 
A strong thread in twisted-pair cables, often used to facilitate opening the sheath over long lengths. It is even called that - a breaking thread. In telephone cables, bundles and layers are separated by it.
Lightly untwist the veins separately. Next, pull out the inside of the socket with contacts. 
As a rule, for any brand, whether it is a TV, an Internet outlet or a regular 220 Volt, there should be an instruction.

Standards and wiring diagram
Open the cover of the contact part and carefully study the markings. Each RJ45 socket can be connected in two ways:
- according to standard “A”
- according to standard "B"
In most cases, the second option is used - "B". To understand where to connect which wires, carefully inspect the case. It should show which standard corresponds to certain contacts.
For example on Unica:
- protocol “B” refers to the top color marking. When connected, you will be guided by these colors.
- “A” - to the lower color marking
If this is sorted out, then with further installation there will be no difficulties. Protocol “B” follows the EIA/TIA-568B color scheme. One side of the clip should have the following colors:
- white- Orange
- Orange
- white- green
- green
On the other side:
- blue
- white- blue
- white- brown
- brown
Pass the wire through the cap. In this case, as mentioned above, the top layer of UTP cable insulation should not be removed by more than 2.5 cm.
You can not strip it under the very wall of the socket, as is done with conventional NYM or VVGnG cables. 
The segment without insulation must be of the minimum length. All these layers are not made easily. Their exact number per 1 meter of cable is strictly calculated and regulated.
Otherwise, with the wrong connection and stripping, not only the speed, but also the quality of data transfer may decrease. 
Then just snap the lid on. Extra segments of veins that protrude outward, You need to cut it off 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 Internet sockets is that with them you don’t need to remove the insulation from the wires at all and expose it to copper. Special knives are already installed inside the outlet itself.
When you close the lid, the knives automatically cut through the insulation and form a contact connection. The instructions for such brands often indicate that when connecting a wire, the use of special crimps-crossers is prohibited.
It's like it's already in the design. That is, when the cover is closed, it cuts off the insulation itself and lays the wires to the desired depth of the connector.
Connecting to the router and crimping the connector
After installing the Internet outlet itself, it remains to correctly connect the cable to the router in the communication board.
Remove the insulation from the other end of the cable by 2-3cm. The cores are fluffed and inserted in a certain order, according to the TIA-568B standard, or simply "B". 
The arrangement of colors is considered from left to right:
- white- Orange
- Orange
- white- green
- blue
- white- blue
- green
- white- brown
- brown
The "A" standard is sometimes used if you need to connect one computer to another. Here you crimp one end of the cable according to the “B” standard, and the other according to “A”. In general, if both ends of the cable are crimped according to the same standard (AA or BB), then this is called a patch cord. And if they are swapped (AB or BA), then - cross.
Again, the veins do not need to be cleaned. Just insert them into the connector until it stops. 
After that, all this is pressed in with a special crimper. Some do this with a thin screwdriver or a knife blade, though this can easily damage the connector.
The cat5E and cat6 cables in the RJ45 connector are crimped according to the same principle. Another "fork" is not required here. Differences between cables in data transfer speed, cat6 has more.
Checking your internet connection
After installing the Internet outlet and the connector at the other end of the cable, it is advisable to check the connection and integrity of all connections. You can do this with the cheapest Chinese device. 
What is its essence? There is a signal generator that sends pulses according to certain codes, and a receiver. The generator is connected at the installation site of the router, and the receiver directly into the outlet itself.
After the pulses are applied, the signals are compared. If everything is in order, the green LED lights on the receiver case light up in turn. If there is an open or short circuit somewhere, then one or more bulbs will not light at all. 
When this happened, then first of all you need to sin on poor contact in the connectors. Most often, it is there, on any core, that the insulation is not completely cut off and, accordingly, there will be no connection.
At the very end, a ready-made tested cable with a connector is connected to the router. 
A complete set of all tools for cutting, crimping, dialing the utp internet cable can be ordered on Aliexpress here (free delivery).
How to connect a 4-wire telephone cable
But what if you use a 4-wire telephone cable for the Internet, and a standard 8-wire socket? How to connect the circuit in this case?
A simple connection by color will not help here. That is, if you insert a white-blue core into contact with a white-blue marking and connect all the other cores in the same color, there will be no signal.
This is explained by the fact that for signal transmission it is necessary to use contacts 1-2-3-6.
On one side, connect two wires to contacts 1-2:
- white- Orange contact = white- orange lived
- Orange= orange lived
and on the other, on pins 3-6:
- white- green contact = white- blue lived on cable
- green = blue lived
In this case, everything should work without problems. Just remember that here the most important thing is not the colors, but the positions. Colors are used to make it easier to visually distinguish the positions of the same core at different ends of the cable.
Also keep in mind that when using 4 wires, i.e. two pairs of twisted pair, you can achieve speeds up to 100Mbps. But for a gigabit network (1 Gbit / s), all 8 wires will already be needed.
Errors when connecting an Internet outlet
1 Incorrect wire connection according to the protocol.
You can easily confuse the order of the cores on the connector and in the outlet itself. Roughly speaking, turn them 180 degrees. 
Here everything is checked by a more careful study of the inscriptions on the body of the socket and the colors of the cores themselves. A tester with a signal generator and receiver is a good helper for identifying such errors.
If the wires are disconnected incorrectly, the tester lights will light up not in order from 1 to 8, but in arbitrary variants. For example, first 1, then immediately 3, then 2, etc. 
2 Not significant, but still considered a mistake, if the wires from the contact plates of the socket are cut off not after closing the cover, but before that moment.
That is, immediately after laying them in their places in the slot. In this case, the core may accidentally fall out, and it will no longer be possible to insert it back cut off. You will have to clean everything up again and go through the entire connection cycle on a new one.
And if you left the supply of cable in the mounting box small, then you will face a big headache.
3 Stripping of external insulation for a long distance, up to the walls of the socket, as in conventional 220V networks.
As mentioned earlier, the result here is a deterioration in the speed and quality of the signal. Moreover, it is not necessary to unwind the twisted pairs beforehand to the place where the insulation is cut, especially with a screwdriver. Just embroider them by pushing the strands to the required length to bring them into the slots. 
According to the standard, it is not allowed to unwind a twisted pair cable by more than 13mm., otherwise crosstalk errors will appear in the frequency response tests. In practice, problems will begin when the network is loaded with traffic.

Connecting the Internet network via cable is the most common way today. Wired Internet is still considered the most stable. For the convenience of connecting it, there are special sockets, thanks to which any cable can be hidden in the wall. Such a seemingly time-consuming task of connection and installation is actually solved relatively easily, without requiring the use of an expensive tool. Therefore, anyone can connect an Internet outlet.
Connection of Internet outlets Legrand, Loop (diagram)
Access to the Internet has become commonplace for a modern person. For simultaneous use of the World Wide Web by several gadgets, of course, one router is enough to provide Wi-Fi wireless communication, but to connect it, you need to install an Internet socket. In the article we will talk about connecting an Internet outlet, consider step-by-step instructions.
This procedure is different from installing a conventional connector, because the design of the device is different and the principle of its operation has nothing to do with a 220V power point. However, having the necessary information and skills to work with electrical appliances, the user will be able to complete the installation himself.
Design features of the Internet outlet
The described products are passive network equipment designed for switching devices to local networks using special disconnectors. Like ordinary sockets, devices for Internet connection, called RJ-45, can be external (overhead), installed on top of the plane and internal (mortise), mounted inside the wall.
Internal socket for internet connection, painted in dark color The main components of a computer connector are:
- front side - which is a decorative panel with a socket for patch cords;
- the reverse (internal) part - which is essentially a terminal block with contacts for wires from an Internet cable.
A twisted-pair network cable is inserted into the outlet, which contains four twists of two wires each. They are divided into eight conductors with different colors.
Appearance and internal structure of the network Internet wire "twisted pair" Each conductor is connected to the corresponding socket contact according to a specific scheme. This connection is called crossover. Its implementation is described in more detail in the next section. Wires are two-pair and four-pair. The former are used in networks where signal transmission occurs at a speed of less than 1 Gb / s. But in our high-speed age, everything is changing rapidly and the data flow in the worldwide network can very soon reach values of several gigabytes per second. Therefore, it is better to use four-pair products designed for speeds up to 10 Gb / s in order to avoid later rework.
Installation and connection of the mains socket
The twisted pair wire is laid in a cable channel or covered with a plinth. The free end is brought out through the socket to the outside (when installing the mortise model) or left open (if the overhead version is mounted). Its length is left sufficient to carry out the necessary work. 7-8 cm recede from the very edge and the outer shell is removed from this area. Conductor pairs are untwisted, separated and straightened. Further steps are given in the instructions.
Step-by-step instructions for connecting RJ-45 with a four-pair wire
- Crimp the wires in the terminals of the socket according to the selected option (the color of the wire matches the color of the contact). For example, as shown in the picture, from left to right: brown, white-brown, green, white-green, orange, white-orange, blue, white-blue. The crimping procedure is best considered as a separate paragraph of this publication.
- Fix the wire with a clamp and carry out a preliminary check of the signal transmission through the connector. To do this, connect the connector from a tablet, laptop or mobile phone to the disassembled device and make sure that there is an Internet connection
- Trim excess wires. Assemble the socket by connecting both parts. Fix it on the wall or in it (depending on the type of execution) in the same way as a conventional electrical point.
At the end, you must again check the performance of the already assembled device by connecting a laptop or other gadget. article: → “How to install and connect the socket correctly? Connection schemes.
Connecting RJ-45 wire to two twisted pairs
The preparatory actions in this case are carried out exactly as in the previous version. The only difference is the connection itself. Instead of eight conductors, four are switched in the wire. The contacts corresponding to the color of the wires and corresponding to the selected scheme "A" or "B" are activated. After that, crimping, assembly and installation of the product, verification of signal transmission is carried out.
An example of cross-connecting an Internet wire with two twisted pairs in an RJ-45 socket Practical advice: It should be remembered that a wire with two twisted pairs is used to transfer data at speeds up to 1 Gb / s. With an increase in the speed of the Internet signal, the wire will have to be replaced and all connections made on it too.
Crimping wires on socket contacts
As stated above. When connecting wires to the terminals of the device, it is necessary to crimp them. The quality of the entire system will depend on this procedure. No need to think that you need to scrupulously remove the sheath from each wiring, and then put it on a bolted connection, as happens in ordinary electrical outlets. For system connectors, the contacts are arranged in such a way that when a conductor is tightly inserted on them, they cut the insulating coating and provide switching with a copper core. In this case, it is not necessary to clean thin wires.
Such a high-quality and reliable connection is achieved when the wire enters the contact terminal as far as it will go. You can use a knife or a thin screwdriver for this. But you must act very carefully so as not to damage the wire. article: → "How to properly connect the wires to each other: terminals, caps, welding, soldering, crimping."

Connecting a connector to connect a computer to an outlet: step by step instructions
To connect a laptop to an Internet outlet, you must have a power cord equipped at both ends with connectors - transitional devices that provide connection to an RJ-45 jack. Crossing the connector to a wire with four twisted pairs is made according to the color schemes suggested in the figure:
RJ-45 connector crossover color scheme according to options "B" and "A" The process of mounting the device on a wire can be represented as a step-by-step instruction:
- The wire at the end is released from the protective sheath, after which the twisted pair conductors are untwisted and aligned
- The wires are distributed according to the colors indicated on the corresponding color scheme and cut to one length - 10-12 mm
- Having placed the conductors tightly to each other, they are all brought into the connector together, after which the correctness of their location is again checked
- Using a crimping tool, the wires are crimped into the connector.
If a crimping tool is not available, crimping can be done with a thin flathead screwdriver. To do this, alternately press each of the contacts of the device with a screwdriver so that it clamps the conductor in it all the way. At the same time, the built-in micro-knife will cut through the wiring insulation and ensure reliable switching. The wiring diagram of the Internet wire on the connector must match the diagram in the outletRJ-45. Otherwise, the connection to the worldwide network will not be available..
Other connector connection schemes
In addition to connecting a computer with an Internet connector, you may need a cable to connect the computer to another computer. In this case, the crossover will be different at different ends of the wire. Also, do not forget about the 2-pair wire, which is also often used for connections.
Twisted-pair crimping schemes for different connections with 4- and 2-pair wires The color schemes shown in the figure will help you cross-connect wires for different connection options. see the article: → "The principle of operation, selection criteria and installation of a GSM socket".
Common mistakes when installing computer connectors
The most common mistakes when installing sockets and connectors are associated with an inattentive attitude to the distribution of wires by color.
Mistake 1. The computer socket is installed independently according to option "B", and the connecting cord is purchased together with the gadget or separately, but already assembled. The user without verification starts to connect. The error lies in the fact that the wire can be mounted according to the “A” scheme, in which case there will be no connection. Before use, you need to make sure that the connector is cross-linked properly.
Error 2. To ensure good contact, the user tries to strip the twisted-pair wires with a knife. The mistake is that it is a waste of time and effort. Signal transmission from such procedures will not improve. Proper crimping ensures fast switching and reliable contact
Mistake 3. Leaving too long a free end of the wire when installing the outlet. The error will be revealed only after connecting the wire, while fixing the device to the wall or inside the wall. If the length of the cable does not allow it to be placed in the socket, then the entire connection procedure will have to be repeated again after shortening it. Therefore, you should not leave a large piece of cord - 15-20 cm is enough.
Mistake 4. Use of a low-quality product of a dubious manufacturer. Installing an Internet outlet is one of those issues that rarely arise. It is for this reason that it is not worth saving and jeopardizing the use of the resources of the global network. It is better to purchase a quality device from a well-known manufacturer. The same applies to cables.
Practical advice: If the user has no idea about working with sockets and wires, it is better not to try to install and connect it yourself. It is recommended to use the services of specialists who will do everything competently and quickly.
In conclusion, I would like to note that the Internet is an outstanding achievement of modern civilization. The attitude to the possibility of access to this resource should be responsible. Properly performed work on the installation of a computer outlet and a cord with connectors will ensure high-quality and reliable communication with the global information system.
An Internet socket, which is used in computer and other communication networks, has a significant difference from connecting and installing conventional electrical equipment. This is due to the presence of a cable for data transmission (twisted pair is used) and the presence of an RJ-45 plug that must be connected to power (8P8C type). These two differences have significantly changed the structure of the connector, because of this, the installation and connection of the Internet outlet has also changed significantly.
What is important to know?
As a rule, a socket with two twisted pairs with four wires is used (eight wires are obtained). Each core is divided by color and has a personal color marking. They are all necessary for fast data transmission.
The 8P8C type connector, which is used to connect to the socket, has the following form:
Manufacturing engineers have spent a lot of effort developing an Internet socket that the user can independently install and connect to the electrical network without having experience and special equipment. In addition, the user must make the connection in such a way that the reliability of the connections and the safety of the contacts remain at the highest level.
Preparatory work
The example uses a product from the Legrand Valena model. Since its mechanism is suitable for many series of Legrand wiring equipment, it has become popular among consumers.
Before proceeding with the installation of a computer outlet with your own hands, it is necessary to install a twisted pair cable. To do this, the end of the twisted pair is output to the socket.
First of all, you need to remove the back cover from the mechanism. To do this, the Internet socket must be turned with the back side facing you. This is done as follows: you need to turn clockwise (approximately ninety degrees) the white retainer. How this is done correctly is shown in the photo below:
After the latch has been turned, it stands perpendicular to the connector body and the back of the structure is easily detached from the device. Then you need to push the network cable (twisted pair) into the center of the back cover, which was previously removed. This is done from the side of the latch (outer side). After that, you need to expose the veins. To do this, carefully remove the protective sheath from the twisted pair.
Connection nuances
On the back cover of the Internet outlet, there are grooves and stickers that indicate in which scheme the device can be connected. There are two connection schemes - these are A and B. Which type to use depends on how the equipment is interconnected.
Today, almost all network structures independently recognize the scheme by which the connection was made and, if necessary, adjust to it. But the network outlet to which you need to connect the mechanism for accessing the Internet is best installed by connecting the wires of circuit B.
According to the scheme, it is required to place twisted-pair wires of a certain color in the grooves of the cover of the corresponding color.
Then we return the cover to its original place. As soon as the lid has taken its seat, close the white latch. To do this, it rotates counterclockwise. It should be noted that incorrect installation of the cover is completely excluded, since the device has special elements that are mirrored on the connector (protrusion and groove). Therefore, it is impossible to set the elements incorrectly.
But, the question arises: how is the Internet outlet connected to the cable, because the insulation was not removed from the wires? This is considered the main difference between the network socket and other wiring structures. The pads with contacts in a computer socket are two sharpened plates. They are located so that the distance between them is equal to the cross section of the copper double core.
Thus, the cover with all the wires inserted is placed in its original place, and these blades cut through the insulation of the twisted pair and come into contact with the cores that conduct current. This connection is secure. It guarantees uninterrupted stable operation of electronic structures. In this case, the work will be carried out without excessive losses.
Then you should make sure that the installation of the cores is carried out correctly and cut off the extra ends of the twisted pair that stick out. The main thing is not to allow accidental closure of any cables to each other.
It remains to install the Internet socket in the socket, fix the front panel. When the connection to the network is made, you can check what the result is. You can install and connect any network device yourself using this method. Even if the contact groups differ in them, the meaning will not change.
For example, there is such a socket mechanism, the connection of which is carried out manually. That is, each twisted pair cord is squeezed into a specific terminal according to the number and, as shown in the photo below. It is a little more complicated and longer than installing the Internet outlet of the Legrand series. But the technology of how to install and connect the device remains unchanged: the cores fall into the hole between the pointed plates and touch the core, which carries the current.
