Network connection of computer devices is carried out using an RJ-45 socket with two or one port, the material of the socket body is usually made of impact-resistant plastic (ABS UL 94V-0).

A computer socket is used to connect equipment on the one hand, on the other hand it performs the function of connecting to a patch panel (For example, a patch panel 19, 1U, 48 Ripo ports).
Varieties of devices overhead computer sockets RJ-45
Each RJ 45 socket (8P8C) is equipped with 8 pins. Models are divided into several types and, depending on this, are applied to various objects.

Buyers can buy the following options:

Model RJ-45 Cat5 (8P8C). The socket is used to form network structures of the 100BASE-TX standard, providing a data transfer rate of 100 Mbps. For example ()
- Model RJ-45 Cat5e (8P8C). This model computer outlet is the most popular and allows you to organize a network operating at a frequency of 125 MHz. When connecting a double pair, the speed is - 100 Mbps. If the number of pairs is 4, the speed reaches - 1000 Mbps;
- Model RJ-45 Cat6. The socket is used in work with network protocols Fast Ethernet, Gigabit Ethernet. The transfer rate is 1Gbps;
- Model RJ-45 Cat6A. Analog previous version except for the increased bandwidth, here the data transfer rate is - 10Gbps.
Along with the specified parameters, the product is distinguished by the type of installation. Allocate an internal method when the devices are mounted in a valid box or invoice. In the latter case, a box is initially installed and already functioning computer sockets are inserted into it.
When purchasing an RJ-45 computer socket, the future owner specifies the number of ports 1 or 2. There are various versions that allow you to connect an RJ-45 or RJ-11 connector.
RJ 45 computer socket components
Installation of products requires prior purchase of components.

One of them is RJ-45 Jack (connector). This is the name of the device that connects the LAN cable and the computer socket. RJ 45 models use 8 RJ-45 plugs. determined by the materials used in the production.
The second LAN cable used to connect sockets is also twisted pair divided into different models. The choice primarily depends on the type of computer outlet, according to which the twisted pair is selected.

The range of twisted pair is:

FTP4 cable number of twisted pairs of conductors: 4/2, category 5e, used for RJ45 cat.5e FTP models with a data transfer rate of 100 Mbps. An example is FTP 4 RIPO CAT 5E 24 AWG Cu;

Unshielded twisted pair UTP4 (4-pair, category 6) used to connect RJ45 cat.6 UTP socket models with a data transfer rate of 1Gb/s. For example RIPO.
If it is necessary to connect a large number of devices, an RJ 45 patch panel is purchased, which is installed in racks or telecommunication cabinets 19. It has a significant number (12-50 pieces) of RJ-45 connectors and pays for its cost many times over. In offices and organizations, a category 5e patch panel is recommended.
If during installation the length of the LAN cable is insufficient, you can use a 2x RJ 45 pass-through adapter. It easily connects twisted pair without loss of signal and transmission speed.

At AVS-Electronics, you can buy a computer socket at competitive prices, as well as get competent advice on SCS elements and other products.

In many families, several devices connect to the Internet: without world wide web we can’t imagine life for ourselves, therefore everyone needs their own line. They work mainly on wireless protocol- Wi-Fi, but the wire is still available, since so far wired Internet more stable than wireless. During repairs, all the wires are hidden in the walls and the "Internet" ones are no exception. They, like electric ones, are plugged into sockets, only of a different standard: they are called computer or information. They can be with different connectors, but the most common is RJ 45. Installation and connection can be done independently, but since the connector looks unusual, there are more than two or three wires in it, and the connection is not provided by soldering or twisting, you need to know how to connect an internet outlet as well as the connector that should be inserted into it.

RJ-45 connector crimp

An Internet cable that enters an apartment or house, which is most often called a twisted pair cable, often ends in a small plastic connector. This plastic device is the connector, and usually RJ45. In professional jargon, they are also called "Jack".

Its case is transparent, due to which the wires of different colors are visible. The same devices are used on connecting wires that connect computers to each other or to a modem. Only the order of location (or, as computer scientists say, pinouts) of wires can differ. The same connector is inserted into a computer outlet. If you understand how the wires are distributed in the connector, there will be no problems connecting an Internet outlet.

Internet cable connection scheme by color

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

To finally clarify all the issues, let's talk about the number of wires in a twisted pair. This internet cable comes in 2-pair and 4-pair. For data transfer at speeds up to 1 Gb / s, 2-pair cables are used, from 1 to 10 Gb / s - 4-pair. In apartments and private houses today, mainly, streams up to 100 Mb / s are brought. But with the current pace of development of Internet technology, it is quite possible that in a couple of years the speeds will be calculated in Megabits. It is for this reason that it is better to immediately expand the network of eight, and not of 4 conductors. Then when you change the speed you do not have to redo anything. It's just that the equipment will use more conductors. The difference in cable price is small, and sockets and Internet connectors still use eight-pin.

If the network is already wired in two-pair, use the same connectors, only after the first three conductors laid according to scheme B, skip two contacts and lay the green conductor in place of the sixth (see photo).

Crimping a twisted pair in a connector

There are special pliers for crimping wires in the connector. They cost about $6-10 depending on the manufacturer. It is more convenient to work with them, although you can get by with a regular screwdriver and wire cutters.

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 twos. Sometimes there is also a thin shielding wire, we simply bend it to the side - we do not need it. We unwind the pairs, align the wires, spreading them in different sides. Then fold according to the scheme "B".

How to terminate an RJ-45 connector in a connector

Wires in right order we clamp between the thumb and forefinger, we lay out the wiring evenly, tightly to each other. Having aligned everything, we take wire cutters and cut off the excess length of the wires laid out in order: 10-12 mm should remain. If you attach the connector as in the photo, the twisted pair insulation should start above the latch.

We put a twisted pair with cut wires into the connector. Please note that you need to take it with the latch (protrusion on the cover) down.

Each conductor must get into a special track. Insert the wires all the way - they should reach the edge of the connector. Holding the cable at the edge of the connector, insert it into the pliers. The handles of the pliers are brought together smoothly. If the body has become normal, no special efforts are required. If you feel that it “does not work”, double-check whether the RJ45 is in the socket correctly. If everything is fine, try again.

When pressed, the protrusions in the tongs will move the conductors to the micro-knives, which will cut through the protective sheath and ensure contact.

Such a connection is reliable and problems with it rarely occur. And if something happens, it's easy to remake the cable: cut off and repeat the process with another "jack".

Video lesson: crimping the RJ-45 connector with pliers and a screwdriver

The procedure is simple and easy to repeat. It may be easier for you to do everything after the video. It shows how to work with pliers, as well as how to do without them, and do everything with a regular straight screwdriver.

How to connect an internet cable to a power outlet

Now we come directly to how to connect the Internet outlet. Let's start with varieties. Like conventional electrical outlets, information ones come in two modifications:

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

Although outwardly computer sockets differ, the principle of connecting conductors is the same for them. There are special contacts equipped with micro-knives. At the inserted conductor, the protective sheath is cut through. As a result, the metal of the microknife contacts fits snugly against the metal of the conductor.

How to connect a computer wall outlet

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

The case is mounted on the wall, usually with the cable inlet up, the computer connector down. The next steps are simple:

Connecting a twisted pair to an outlet is really a simple procedure. Even the first time it will take a few minutes. Once again, you can see what and how they do in the video. It first shows the connection of an Internet cable with 4 wires, then with 8.

How to connect an internal internet outlet

We will not describe the installation of a plastic box - this is another topic. We will understand the features of connection and assembly. The main snag here is how to disassemble computer sockets. When connecting conductors to them, it is necessary to get to the contact part: a small ceramic or plastic case with built-in microknife contacts. The conductors are connected to this mounting plate, and then the case is assembled again. And the whole problem is that different manufacturers they are assembled/disassembled differently.

For example, at the popular manufacturer of computer sockets Legrand (Legrand), in order to get to the connectors in the Legrand Valena RJ45 computer socket, you need to remove the front cover. Under it, a white plastic impeller (as in the photo) will be found, on which an arrow is applied.

It is necessary to turn the impeller in the direction of the arrow, after which the case and the contact plate will remain in your hands. It has color-coded conductors. The connection is no different, except that - first, you need to thread a twisted pair into the hole on the plate, and then spread the wires.

For clarity, watch the video.

Another popular manufacturer of such equipment is Lezard (Lezard). He has a different system. The front panel and metal frame are fixed with small bolts. They are easy to unscrew, but the internal contact plate is held on by clamps. Assembling and disassembling Lezard computer sockets (Lezard) in right places it is necessary to wring out the contacts with a screwdriver.

To remove the plastic contact group from the housing, it is necessary to press on the latch located at the top. After that, you will have a small box in your hands. But that's not all. It is necessary to remove the plastic cover that closes and presses the conductors. Remove it by prying the side petals with a screwdriver. The plastic is elastic and the effort required is quite decent. Just do not overdo it: it's still plastic. After that, the wiring is standard: according to the markings applied on the sides (do not forget that we use the "B" scheme).

If you know how to connect an Internet outlet, even with an unfamiliar model, it’s easy to figure it out. And now you can upgrade your network yourself (increase the length of the twisted pair cable, move the computer to another location, make another connection point, etc.), without involving specialists. One more question remains: how to connect double sockets. Two cables are brought to them and then there is a color scheme. This is possible when your network is formed by a modem or two Internet lines come in. Is it possible to embroider both inputs with one cable? It is possible, but you need not get confused in the color designation of the wires in the further wiring of the network (remember which color you used instead of which one).

Information sockets brand RJ 45 have an increased number of contacts. There are 8 point contacts per module, unlike the usual 4 in RJ 11 connectors. Modular computer sockets from the SvetElectro.net store presented in several factory categories. The frequency, speed and transmission range of a “clean” signal directly depend on the brand chosen.

Categories and purposes of Internet sockets

• Category 5. Reference material. Designed for point network organization. Average clean signal speed 100 megabits/s
• Category 5e. Improved version of the 5th category. It is used in paired (and more) networking. The transfer rate depends on the number of modules: from 100 megabit/s in the basic version, up to 1000 megabit/s in four pairs.
• Category 6. The most "high-speed" of the presented. The average is 1000 megabits / s.
• Non-categorical "UTP" "FTP". Thanks to the removable modules, in both types, it is possible to combine from any category. Easy to maintain, one of the most practical.

When buying computer sockets for the needs of the office, modules with additional ports are most often used. The main advantage of such models is multitasking. So one socket with two combinations of modules can have different potential. This allows you to optimize costs and increase overall efficiency. For domestic use, any RJ45 Internet sockets are suitable. Since the prices of high-quality modular sockets in the SvetElectro.net store are quite affordable, you can consider each option presented.

Types of computer sockets by type of installation

External mounting - computer sockets are mounted on any convenient surface with open access. Modern models are equipped with a lightweight installation system. The special clip-connector is equipped with cutting shelves. When installing, it is enough to push through the wire and the contacts themselves are exposed. Removable protective boxes consist of heat-resistant materials with a protective coating. Long-term heating of the surface does not lead to melting and other consequences high temperatures. Such sockets are the safest for intensive use.

Internal installation - conditionally divided into hidden and classic. Installation of classic internal RJ 45 computer sockets is no different from installation of household sockets. Hidden, more often used when it is not possible to carry out serious installation work (chasing and drilling walls). Easily mounted on plasterboard walls, wooden surfaces - computer and office tables. Flush-mounted systems carry not only a practical load, but also a decorative component.

To beautifully organize the connection point of a computer or other device to a wired local network or Internet cable, a special socket with an RJ 45 connector is installed on the wall.

In this case, the hanging "tails" of the cable will not spoil the interior, and the probability of their damage will be reduced to zero. In this article, we will discuss the connection of the RJ 45 socket.

Computer sockets are available in a variety of designs. According to the number of connectors, they are divided into:

• single;
• double;
• terminal: have from 4 to 8 connectors.

By placement:

1. Embedded: the main part of the outlet is hidden in a recess in the wall, only a decorative patch panel remains outside. To lay a cable to such an outlet, you have to ditch the wall.
2. Overhead: the entire socket is in plain sight (screwed to the wall). The cable to is not laid along the wall in a box or openly (fixed with clips). You don’t have to hit the wall, but the appearance of such an outlet is worse than that of a built-in one.

Also, computer sockets may differ in the type of connectors. In addition to RJ 45 jacks, they can be equipped with connectors for connecting audio systems, telephones, etc.

Another distinguishing feature of computer sockets is the category. It must match the network bandwidth:

The installer will need:

• screwdrivers: slotted and cross;
• stripper - a tool for removing insulation from wires (can be replaced with a knife);
• crimper: tool for installation on the RJ45 handpiece ethernet cable;
• a tool for chasing the wall, if necessary: ​​a puncher, a grinder with a stone disc or a wall chaser (depending on the wall material).

In addition to the tools you will need:

• Ethernet cable ("twisted pair") of the same category as the computer outlet;
• switch (also called a router or router): required if you connect a socket with several RJ 45 connectors or several single sockets;
• RJ 45 connectors (when connected via a switch);

You also need to purchase a box or a corrugated pipe: the first is used when laying the cable along the wall, the second - in the strobe.

Work order

Before proceeding directly with the installation of a computer outlet, you must do the following:

1. For a built-in socket: knock out a recess in the wall under the inner part of the product and install a socket box in it. The recess is made with a perforator.
2. Cutting recesses and channels (strobe) in the wall is accompanied by the formation of a large amount of dust, therefore, before starting work, furniture and appliances should be taken out of the room or covered with plastic wrap.
3. Lay an Ethernet cable to the installation site.

Connecting an RJ-45 socket: diagram

Let's consider two options:

1. A single outlet is installed. In this case, a cable is laid that was brought into the room by the provider. In this case, the place for the outlet must be chosen so that the “tail” of the cable with a length of at least 20 cm remains in the socket (for ease of installation).
2. A socket with several connectors or several sockets is installed. In this option, a switch is first installed in a convenient place and the cable brought into the room by the provider is connected to one of its ports. Further from the switch, several cables are laid - according to the number of connectors in the socket. Each cable is included in separate port switch.

If a switch with a Wi-Fi transmitter is used, it cannot be installed in a metal cabinet.

The Ethernet cable is laid away from electrical wires, otherwise they will interfere. If it is not possible to maintain a sufficient distance, a shielded cable is used.

The following options are used:

• along the wall: in a box or simply on special clips;
• inside the wall (a strobe is cut out): in a corrugated pipe, which will make it possible, in which case, to replace the cable without opening the strobe;
• under the plinth;
• behind a false ceiling.

You can not bend the cable, since its cores are quite thin (designed for weak currents) and therefore can easily break.

Connecting a Legrand computer outlet

Legrand products combine affordable cost, high quality, great variety and good design, which is why it is one of the most popular.

It would be logical to consider the installation order using the example of a socket of this brand:

1. If it is supposed concealed installation, the ethernet cable inserted into the socket is cut to a length of 20 cm. With such a length, it is convenient to work, and the cable will fit in the socket. If this is a cable brought into the room by the provider, then before cutting the RJ 45 lug installed on it, you should remember the order of the cores (according to the color marking of the insulation). The wires are connected to the socket in the same order, otherwise there will be a discrepancy with the order of the wires at the opposite end of the cable (it is plugged into the provider's switch) and the network will be inoperative.
2. The end of the cable with a stripper or a knife for a length of 2 cm is freed from insulation and a shielding layer, if any. Core insulation marked with different colors does not need to be removed.
3. The veins are untwisted (they are twisted in pairs) and lined up in the correct order. Their ends are cut with a crimper at a right angle to the axis of the wires.
4. Having freed the socket from the front panel, turn it with its back side and unscrew the lock located there counterclockwise. This will release part of the clamping mechanism - it must be removed.
5. Passing the cable through the hole, lead the wires into the terminals. Those are also color-coded, but it is not necessary to follow this marking. Remember that when connecting an Internet cable, the cores are installed in the order in which the provider installed them when installing the RJ45 tip.
6. The removed part of the clamp is returned to its place and the latch is rotated clockwise. In this case, the cable will be crimped: miniature blades will pierce the insulation and pierce the cores, providing high-quality electrical contact.
7. Next, check the performance of the outlet. To do this, you need to connect a computer to it with a patch cord or wifi router and make sure you have an internet connection.

If everything works, the socket is installed in the socket. In order for it to fit completely there, the cable in the socket is distributed evenly, while avoiding kinks. Next, screw the frame with screws and install a decorative panel.

Installation in cabinets

For mounting an Internet outlet in a cabinet, special DIN tires are produced. Recall that a router with a Wi-Fi transmitter cannot be installed in a metal cabinet: metal walls absorb the radio signal.

Connecting the cable to the outlet is carried out according to the scheme described above.

Switching

An important point - the order lived when connected to the outlet. For an Internet cable, follow the order adopted by the provider when installing the connector. In other cases, proceed in accordance with the purpose of the outlet.

When connecting an outlet to a switch (router)

The cores are installed in the same order as they are installed in the RJ45 lug from the switch side (direct connection).

The sequence of colors can be arbitrary, but in order to avoid mistakes in the future, it is better to adhere to the generally accepted scheme:

• white-orange;
• Orange;
• white-green;
• blue;
• white-blue;
• green;
• white-brown;
• brown.

If the socket is set to connect the computer to the computer

In this case, a cross connection is used: on one side of the cable, the cores are placed in the indicated order, on the other, the white-green and green cores are interchanged, respectively, with white-orange and orange.

After installing a computer socket, the user does not have to worry about the safety of the cable: completely hidden in a box or wall, it will not be damaged during cleaning or due to repeated kinks when dragging. In addition, the socket looks more aesthetically pleasing than a protruding cable tail.

Despite the fact that wireless communications are developing quite quickly, the UTP socket is still in great demand. After all, it is this product that is an indispensable element in the structured cabling system of a modern building. The socket itself is referred to among specialists as RJ-45, its versatility allows you to connect UTP twisted pair cable without unnecessary devices. Moreover, you can install such a unit yourself.

Short description

Outwardly, the RJ-45 computer socket most of all resembles a standard RJ-11 telephone device. The main difference between these two devices is only that the number of connector pins has been reduced from eight to four. Therefore, a computer socket can be used for a telephone, but not vice versa.

Depending on the model, the final unit may differ from its counterparts in small characteristics, but the whole design concept remains the same. Professionals claim that The quality of the outlet is determined by three main points:

It is the exact number of ports that is considered the main indicator of such a device. Most often there are no more than four. If the user plans to connect much more devices, it will require an additional patch panel. It is worth noting that the acquisition of such a device can only mean that the master did not foresee all the nuances at the stage of network wiring.

A large number of installed patch cords can cause a lot of inconvenience. For high-quality arrangement of a home or office LAN, you can use two-unit modules.

The installation method of this switching unit depends on the version in which the socket is made. Experts have provided for the presence of two proven methods:

1. For indoor installation.
2. Outdoor installation.

The choice of one or another option depends on the method of laying the LAN cable. If it is external (for example: the wire is placed in special boxes), then only external sockets will come in handy. If the master preferred hidden wiring, then internal fixtures will look more impressive and neat.

Separately, it is worth noting that the RJ-45 network socket is sometimes installed directly on the box itself. AT technical terms such execution can be considered both external and internal. In addition, the performance characteristics are completely independent of the performance of the LAN.

It depends on the characteristics of the cable that the fact to which category it belongs. Its demand is due to a wide bandwidth, as this indicator affects the speed of data transfer, as well as the possibility of using special high-quality Internet technologies. The masters always have a table for this case, which clearly shows the relationship between the outlet category and the bandwidth.

Development of modern information technologies influenced the fact that during the installation of the LAN, cables lower than UTP 5e are practically not used anywhere. In order for the result of the performed manipulations to fully meet all expectations, it is necessary that the category of the outlet is not less than that of the wire connected to it. Otherwise, there is a high probability that the data transfer rate will be reduced several times.

Design features

The professional connection of the RJ-45 socket may differ in the external or internal type of execution. Each option has its own advantages and disadvantages. The main positive characteristics of indoor installation include compactness and hidden cable routing. In addition, the product itself will be reliably protected from any mechanical influences.

Disadvantages indoor installation practically none, the only thing is that if necessary, the user will not be able to move the outlet to another place, and the installation process itself is always accompanied by certain repair work. In this regard, overhead models R-45 cat 5e are the most popular today.

The modification of each device differs in the total number of connected users. Each model is designed to connect one, two or more wires. Depending on the chosen installation scheme, the master can use both single-sided and through-hole sockets.

Pinout principle

A high-quality connection of a twisted pair cable to an outlet is possible only if the master correctly pinouts the wires. There should be no problems with this task, since in front of each contact group, manufacturers have provided for a special color coding which fully complies with all established standards. Regardless of which option the master decides to use, the main task is to make it the same type for the LAN. Otherwise, some problems may arise.

Many people think that in Russia everyone “compresses” the wire according to the T568 B type, but this statement is very conditional. The easiest way is when the user knows what standard his provider uses. You can also determine this yourself by looking at the pinout of the connector that is installed on the cable introduced into the apartment.

Connector crimping instructions

You need to start by choosing professional tools that will be useful for introducing twisted-pair sockets. Of course, better buy a quality extractor, which allows you to quickly press in and cut off the rest of the unnecessary wire with one touch of the hand. The Chinese equivalent of such a tool costs about $5. Advertised models can cost three or even five times more.

The extractor provides for the presence of a universal mechanism that allows you to quickly and efficiently press the wire between two contact knives, cutting off all excess. In addition to this, the unit is equipped with a flat screwdriver and a small hook, which is designed to carefully remove the wire if it is incorrectly terminated.

During operation, universal pliers are sure to come in handy for the accurate removal of the insulating layer. Their cost is almost the same as that of the extractor. Such a tool does an excellent job with a cable such as UTP, FTP, STP. In addition, the user can independently adjust the depth of the incision. Experts do not recommend using an ordinary kitchen knife to strip insulation, as the risk of damage to one of the cores increases significantly.

When the choice of tools is over, you can safely proceed to the main algorithm for terminating a twisted pair into a switching device. An example will be given on the assumption that the main cable has already been laid, the seat for the socket has been prepared. The scheme of actions is as follows:

It is worth noting that you can meet craftsmen who recommend using an ordinary clerical knife instead of a professional tool. This method is valid only when you need an urgent Internet connection, but the extractor is not available. But at the first opportunity, such an outlet will need to be pinched, since the contact of the wire with the latch will still be broken.

When the twisted pair is pressed in, the module must be installed in its original place. If socket external configuration, then its base must be screwed to a pre-prepared site. As a result, the cable should be fed from above, and the connector along the contour from below. If the socket is internal, then its base is mounted in a special glass, after which it is fixed.

It remains only to screw the front panel and check the operation of the device. This can be done by a professional tester, but it is much easier to connect a computer. If network connection no, the first step is to check the correctness of the pinout, since in 99% of all cases this is the problem.

Installation of a hidden socket

Beginning masters often have difficulty with how to properly disassemble such a computer device. When connecting all the conductors, it is necessary to gradually get to the main part - a small case (most often plastic or ceramic), where miniature contacts are located. It is to this plate that all the conductors are connected, and then the case is assembled. The thing is that different manufacturers carry out this procedure in different ways.

For example, the well-known brand Legrand produces sockets in which the main connectors are hidden behind the front cover. Having removed this part, the master comes across a white plastic impeller, which contains a small arrow. The impeller must be carefully turned in the direction of the arrow, after which access to the housing and the contact plate will open. It is on it that the multi-colored marking of the conductors is applied. The final connection practically does not differ from a standard outlet, the only thing is that initially you need to thread a twisted pair into the hole on the plate, and only then level the cores.

No less popular today is the Lezard trademark, which manufactures computer sockets in a different way. The metal frame and front panel are fixed with small bolts that can be easily unscrewed. The main internal contact plate is fastened with special clamps. When assembling and disassembling such a socket, you need to know that some contacts can only be squeezed out with a screwdriver.

But to remove the contact group from the case, you must gently press on the top latch. After these manipulations, the master will have a small box in his hands. To connect a twisted pair, remove the plastic cap that presses the conductors. Since the plastic in this place is quite elastic, then the effort should be significant. It remains only to separate the cores according to the markings applied to the product.

When it is decided to use a shielded cable, then the socket must be selected appropriate, where the connection of such a product is provided in advance. Otherwise, the screen will turn into a huge antenna, which will negatively affect the bandwidth and speed of the Internet. It is for the same reason that you should not buy an FTP cable if it is not provided for connecting powerful ungrounded equipment.

To make full use of high-quality twisted-pair LAN technologies, you need to equip entire lines. Twists and spikes in this case are simply unacceptable, as this is fraught with serious speed losses. In cases where it becomes necessary to extend a certain length of cable, only special connectors should be used. Such a device is presented in the form of a small box in which a powerful board with two RJ-45 connectors is mounted. In some models, twisted-pair latches, like sockets, may be provided.

You should not buy products with a large number of ports for domestic conditions. Numerous patch cords that are installed in one place will definitely begin to get tangled, giving users some discomfort. It is best to make several outlets at different distances.
