Crimping twisted pair RJ45 circuit. We crimp the network wires with RJ45 connectors. Pinout of wires for creating a local network

As a rule, Internet users most often encounter this problem. One of the common reasons for lack of access to " world wide web» – inaccurate line switching, when cables are literally lying under computer desk and systematically break off at the points of connection.

Although it is often necessary to change its routing, thereby increasing the length. For example, when changing the position of the PC or telephone set in the home. In any case, you cannot do without reinstalling (or attaching a new) RJ-45 connector. Let's figure out how and with what you can compress it at home network cable RJ-45 connector.

The RJ-45 connector is often designated by the symbol “8p8c”. It is simply deciphered - this connector has 8 contacts and inserts (so-called knives). There are several modifications of this switching element. Depending on the design features, the specifics of its application also differ. RJ-45 having 3 protrusions are considered universal. They are used for crimping both single- and multi-core cables, which is why all patch cords are made with their help. The connector diagram is shown in the figure.

Necessary tool

In fact, you only need a special device for crimping RJ-45 cables - a crimper.

It is inexpensive (between 638 - 689 rubles), and in order not to constantly call a specialist, it is advisable to purchase it, although the crimper does not belong to the class of household tools. In any home there are many connection points for lines (telephone, computer) that are organized using RJ-45, and this device will definitely be needed again, and more than once.

Sharply sharpened cutting tool. As a rule, a scalpel is used to prepare the cable for crimping. They are much more convenient to work with than a knife. And the cutting of the conductor is more accurate.

Before you begin the crimping process, you should make sure that the RJ-45 is suitable for the type of cable you have. Although it’s worth thinking about this when choosing a connector in the store.

Network cable crimping technology

Twisted pair (network cable) is sold in coils. Therefore, it is necessary to lay the cable around the room according to the selected (drawn up) diagram and cut it to length, taking into account a small margin.

A layer of external insulation is removed (2.5 ± 0.5 cm) at the end of the cable that is supposed to be crimped. Either with a scalpel, or with a miniature knife (available on the crimper itself). It is necessary to carry out the work so that the coating of the cores themselves is not damaged. That is why those who do not have sufficient experience in this area are recommended to trim twisted pair, leaving some margin in length. The explanation is simple - it is not a fact that you will be able to perform this operation accurately the first time.

The veins unwind and straighten. If their tips are not aligned, they can be bitten off (with side cutters, about a millimeter and a half). Otherwise, it will not be possible to position them correctly in the RJ-45. The standard by which the connection to the network is made is also taken into account.

Direct crimping. There are two methods - straight and cross (oblique). The first method is implemented by connecting the PC to the Internet line. The second is when creating local network, that is, when connecting two computers.

Feature of the operation

• When laying conductors in RJ-45, the wires should not cross, and even more so, should not be placed in pairs in 1 connector socket - only one at a time. This is typical for their tips, which can become twisted as they are pressed into the connector body.
• Before you begin crimping, it is recommended to check the wire layout again. That is, carry out a control inspection, since it will be impossible to change anything later.
• Installing a crimper at the cable crimp site. Then simply squeeze the handles of the tool. The main thing is not to overdo it.

Checking the line's functionality. In practice, this is done by connecting a cable to a PC. The result will be clear immediately.

If a patch cord is made (with rj-45 at both ends of a piece of cable), then, in the absence of a special test device, you will have to. To do this, its probes should be sharpened so that they can ensure tight contact with the miniature lamellas of the connector. Next - dialing for each conductor. If everything is in order, you can connect both PCs to each other.

In principle, there is nothing complicated about crimping cables. If you have a crimper, then installing one RJ-45 takes just a few minutes.

Computer local and Internet networks are created using special cables. And in order to reduce the impact of various interferences, it is used twisted pair, which is laid from the router to the computer or between PCs. Specialists of the portal “2 Schemes” will tell you in detail about the types of such cables, their installation and features of use. The cable design consists of 8 cores, which are twisted together and placed in a common braid.

Types of color schemes for crimping LAN cables

Multiple crimp color schemes available per EIA/TIA-568 specification lan cable twisted pairs (patch cords) into an RJ-45 connector for connecting computers to a router, hub, switch, or connecting two computers to each other.

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, for example, a computer with a hub, switch, or two computers together. To make a patch cord, you take a twisted-pair cable, the cores of which are made of stranded wire so that they do not break due to frequent kinks. To crimp such a cable, special RJ-45 connectors are used.

Types of cables for the Internet

Shielding provides better protection from electromagnetic interference, both external and internal, etc. The screen along its entire length is connected to a non-insulated drain wire, which unites the screen in case of division into sections due to excessive bending or stretching of the cable.

• Unprotected twisted pair(UTP - Unshielded twisted pair) - there is no protective shield around an individual pair, most often this is UTP category 5 and higher;
• Foil twisted pair(FTP - Foiled twisted pair) - also known as F/UTP, there is one common external screen in the form of foil;
• Protected twisted pair(STP - Shielded twisted pair) - there is protection in the form of a screen for each pair and a common external screen in the form of a mesh;
• Foil shielded twisted pair(S/FTP - Screened Foiled twisted pair) - an external screen made of copper braid and each pair in a foil braid;
• Unprotected shielded twisted pair(SF/UTP - Screened Foiled Unshielded twisted pair) - double external shield made of copper braid and foil, each twisted pair without protection.

Crimping twisted pair with a screwdriver

You can crimp a network cable without a crimper. If you don’t have a special tool at hand, you can use a regular flat-head screwdriver.

You can really crimp it reliably with a screwdriver - there’s nothing complicated here, the main thing is to properly align the wires in advance so that they fit evenly and stay in the connector, and then carefully press the metal plates with a screwdriver, turning them over and placing the connector on a flat surface. You will clearly feel that the pressure is enough - the braid is broken and the wire is securely fixed. You need to press with the tool until the latch stops protruding beyond the edges of the connector. Only in this case will the electrical wire be securely fixed and secured.

Technology of cable routing in the socket

The pinout of the RJ45 socket does not require any specialized equipment, you will need only one tool - nail scissors or a small knife with a thin blade. Here is the sequence of actions:

1. The top layer of the winding is cut off. The cut length is about 10 cm for ease of wiring.
2. The twists of all pairs are unwound and the wires are aligned so that from the base of the top layer to the tips of the wires they do not intersect.
3. Any socket has two color markings. “A” — cross connection, “B” — standard connection. By latest marking and RJ45 pinout is carried out.
4. Having attached the base of the braid to the board, first the cores are inserted into the far connectors. Be sure to check the cable tension so that the distance from the braid to the clamp does not exceed 3 cm.
5. Having secured the cable cores in the required connectors, crimping is performed. Holding the nail scissors so that the angle of the cutting guides is 45 degrees, you need to press on the core from above until you hear a characteristic metal click.

When installing a power outlet on a wall, the connectors should always face down. This protects the contacts from becoming clogged with dust and moisture, and when fast connection cable from below, there is less chance of accidentally knocking down the socket mount on the wall.

Reduced Internet or network speed

If the cable is cheap and very long, then, as a rule, it is rarely possible to increase the speed with this option by more than 10 megabits in practice - the system itself will lower it by switching to the only possible stable option. More low speed possible because the connectors were poorly crimped - the contact plates did not clearly penetrate the wire braid.

Despite the advances by leaps and bounds wireless technologies, in an apartment building or private household desktop computers, TV set-top boxes, file storages are best connected using a cable or twisted pair. To do this, it is important not only to correctly route the wire around the room, but also to crimp the RJ-45 standard connectors at the ends of the cable.

Types of cables for Internet connection

Depending on the type of provider, the cable can be routed to the subscriber in several ways. If the connection is made using the Wi-MAX, LTE or 3G standard, there may not be a cable at all.

Telephone cable

Used when connecting to the Internet using aDSL technology. The wire is used in two- and four-core wires; when using four wires, you can increase the length of the cable route and reduce interference. In some cases, a wired telephone is also connected via the same line. To connect, use a special cable modem or modem router.

Often, a single-core copper “noodle” is used for the last mile of a telephone line; the speed and quality of such an Internet channel will be low

Providers use this type of cable to connect network subscribers cable television. Thanks to the wide bandwidth coaxial cable transmits both data and analog TV signals without mutual interference. As is the case with telephone line, a special modem is used for connection.

Coaxial cable is used when laying dual-use networks, for example, Internet + analog TV

Fiber optic

Fiber optic cable is used to connect either multi-storey buildings, with the installation of subscriber routers in the entrances, or houses in the private sector, since this type of cable transmits the signal over vast distances without reducing the signal level or interference. A converter, or interface converter, allows you to connect a router-router to such a cable using a patch cord made of ordinary twisted pair (UTP).

Fiber optic cable is used for laying long and interference-free routes

Twisted pair (UTP)

This is the most common and inexpensive type of connection. These cables bring the Internet to an apartment or house, and also connect client devices (computers, TV set-top boxes, printers) to the router. Cables come in four and eight cores. Four cores transmit data at speeds of up to 100 Mbit/s, and the eight-core version allows you to increase the speed tenfold.

UTP-8 is the most common wire for laying a local network

Without additional amplifying equipment, the length of cable routes will be small (up to 100 meters). Nevertheless, twisted pair connection is a popular type of connection due to the low cost of the wire and connectors, as well as the ability to cut the cable with or without a cheap tool. Whatever wire enters the house, the good old twisted pair will still go after the interface converter or cable modem.

Types of twisted pair

The wire for creating patch cord cables and cable routes differs both in the insulation material and in the composition of the central core (conductor). The cheap one is made of aluminum conductors and plastic insulation, designed for indoor use. Electrical resistance aluminum is higher than copper, and the signal in such a wire attenuates faster. Accordingly, it is worth making only short cables for indoor use, for example, connecting computers in an apartment or small private house to the router.

Use a cheap one UTP cable only indoors and when creating short network segments

The expensive wire is supplemented with another layer of insulation and a thick steel core, which takes on mechanical loads when suspended. Protected frost-resistant wire with copper conductors costs 3–4 times more, but with its help you can lay long sections of cable routes inside entrances and even between individual houses. It is worth noting that in lately Such routes are increasingly being made using fiber optic cable.

Protected twisted pair cable is equipped with additional insulation and steel wire for suspension

Tools required for crimping twisted pair cables

You will need crimping pliers (for 99% of the job), a utility knife or a strong utility knife, and a small flashlight.

Crimping pliers, or crimper, are the cableman’s main tool.

From consumables You will need UTP wire and RJ-45 connectors. If the connectors do not come with silicone caps, a hot glue gun will be useful.

Using RJ45 connectors with silicone caps will not only protect the cable from damage, but also make the connection clearer

If there are no mounting pliers, a small hammer and a flat-head screwdriver with a blade width equal to the width of the contact group of the RJ-45 connector will serve as a substitute.

A cable tester - a device for checking crimped cables - will be extremely useful. If there is a break in the cable or there is no contact in one or two wires, the connection will become unstable.

The cable tester is indispensable for large volumes of cable work and long routes.

Twisted pair crimping circuits

Regardless of the number of cores, cables are divided into two types: straight and crossed. Crossovers are used to connect two computers into a peer-to-peer local network, without a router. If you use a router to build a network, then use any type of cable, since the router automatically detects which cable is connected.

Crimping 4-core cable

A four-core cable can be used indoors at network speeds up to 100 Mbit/s. If you examine the connectors of an inexpensive 100-Mbit router, you will find that each socket is equipped with only four contacts and using an 8-core cable will not provide any advantages. You can perform straight or cross crimping.

Direct crimping of four-core patch cord

The difference between the two types of crimping is the location of the orange and green cores.

Cross crimping of four-core patch cord

Crimping 8-core cable

There are more options for pressing in an 8-core cable, which is not surprising, because local networks with such a cable are the most common. Direct cable pressing can be done in two ways; they differ in the location of the orange cores. Type T586B is a de facto standard in the Russian Federation, and type T586A is common in the European Union and the USA.

Type T586V - the main one for crimping direct patch cords in the Russian Federation

The standards differ in the location of the green and orange cores. Core colors may vary depending on the cable manufacturer.

Type of crimping T586 is practiced in the USA and EU countries

Cable cross-crimping also has two options: for low-speed networks (10–100 Mbps) and for modern gigabit LANs.

Simple crimping is suitable for low speed networks

The difference between simple and cross crimping is the location of the blue and brown wires.

Use cross-pressure for high speed networks

How to crimp a patch cord cable using pliers

Prepare your tools: pliers, a flashlight and a knife.

1. Using the miter knife of the pliers, straighten the end of the cable. If the cable was cut in a store with a regular knife, the end is probably beveled.
2. Remove the insulation from the network cable. To do this, place the cable in the recess of the stripping tool so as to remove the insulation by 2–2.5 cm. Rotating the cable relative to the knife, cut it along the entire circumference. Remove the cut piece of insulation to expose the colored strands.

   Remove the cable insulation using a special tool

3. Unbraid the veins. The length of the unbraided section should not be more than 12–13 mm. If it is difficult to align the strands, you can unbraid them to a greater length, and then trim the unbraided and aligned end.

   The wire strands are unraveled to a length of 12–13 mm

4. Align and arrange the unbraided strands in that color scheme, which corresponds to the cable type.

   Align the cable cores according to the color scheme

5. Taking the new RJ-45 connector, unfold it with the plastic lock facing down and carefully push the end of the cable into it along the guides. The vinyl chloride insulation tube must reach the inner lock tooth in the connector. If the wire is not inserted completely, the wires may come off.

   Carefully insert the unraveled end of the cable into the connector

6. Check that the wires in the connector are in order and not damaged. If everything is fine, insert the connector into the connector of the crimping pliers and squeeze them all the way, but not too much.

Crimping patch cord without pliers

If you rarely crimp cables or decide to help a friend, but the pliers are left at home, crimping can be done with improvised means that everyone has in their pantry. You will need a flathead screwdriver, a utility knife with a new blade, and a hot glue gun.

1. Align the end of the cable with the blade of a sharp knife. Then, stepping back 2–2.5 cm from the end, make a neat circular cut on the insulation. Try not to cut through it so as not to damage the colored wires. After turning the cut section of insulation back and forth several times, separate it.

   Strip the cable insulation using a regular knife

2. Unbraid the wires so that the length of the unbraided section does not exceed 12–13 mm. If you have difficulty aligning the strands, unbraid them to a greater length, and then trim the unbraided and aligned end.

   You can trim the wires to the desired length with wire cutters or a regular knife.

3. Align the braided wires and arrange them in a color scheme that matches the type of cable being crimped.
4. Now take the new RJ-45 connector and unfold it with the plastic lock facing down. Then carefully push the end of the cable into it along the guides. The insulating vinyl chloride tube must reach the inner lock tooth in the connector. If the wire is not completed to the end, the cores may come off during cable operation. Inspect the connector: the wires must be positioned correctly.

   Check that the wires are positioned correctly. If you make a mistake, you will have to cut off the connector and crimp on a new one.

5. Using a screwdriver, push each of the eight pins down so that they cut into the corresponding colored wire. Place a screwdriver on the contact and press it down. There are only a couple of free millimeters in the connector for maneuver; if you overdo it, you can easily damage it. Repeat this action seven more times.

   Press the connector pins down until they penetrate the cable cores

6. Using a heat gun, fill the inside of the connector with glue to secure the cable insulation in it.
7. Check the quality of the crimp by connecting the cable to an RJ-45 socket (router or laptop). If the connector does not snap fully into place, remove it and repeat steps from step 5.
8. When the cable has passed the test, it is ready for use.

There is nothing complicated about crimping a twisted pair cable. Half an hour with a special tool or a little longer with improvised means - and your home local network is already working, and the cable connection is pleasing maximum speed and no delays. Remember that a device with a cable Internet connection works faster than over the air and also reduces exposure to high-frequency radiation.

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

Basic Concepts

A special type of cable intended for the manufacture of computer and telecommunication networks is called “twisted pair”. It consists of several pairs of copper conductors in insulation, twisted together with a certain number of turns per unit length. The most common is 8-core twisted pair. All conductors are placed in a common polyvinyl chloride (PVC) sheath.

A slight twisting or twisting is done in order to neutralize interference from electromagnetic radiation generated by the conductors themselves and third party sources. Because when the veins are close together, the result they create electromagnetic radiation cancel each other without creating signal loss. In addition, external interference is caught by two twisted conductors in the same way, and therefore is easily recognized by the receiving device and cut off. The end result is quality digital signal with minimal losses.

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

Types of twisted pair

1. UTP - twisted pairs are not shielded, there is no external shield. The most common type for apartments computer networks, when there are no large interference and distances.
2. FTP - twisted pair cables are not shielded, but there is an external foil shield. It is used in small offices where it is necessary to transmit data over distances of up to 100 m without loss of speed, and where interference occurs.
3. STP - each twisted pair is braided with wire protective screen, there is an external screen. Used in medium-sized offices and establishments where there may be interference. Allows you to maintain signal quality when transmitting to long distances, but not higher than 100 m.
4. SF/UTP - twisted pairs are not shielded, but there is an outer copper braid and foil film that make up a double shield. They are used in enterprises to maintain signal quality over long distances and to protect against interference.
5. S/FTP - each twisted pair is shielded with foil, there is an external shield in the form of a copper braid. It is used in enterprises with large interference and where it is necessary to maintain the speed of information transmission over a long distance.

The cable insulation color gray is the most widely used. The color is red or orange - it means the insulation is made of non-flammable material.

Two ways to crimp twisted pair cables

The Rj-45 computer cable is connected to the device using an 8P8C connector (an abbreviation of the English words 8 positions, 8 contacts). This connector is installed on the cable by crimping a twisted pair of 8 cores according to the color scheme, depending on the telecommunication standards.

Standard 568-A is obsolete and 568-B is most often used.

Following the diagram, the cores for the 568-A system are laid out as follows:

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

The order of colors when crimping twisted pair cables according to the 568-B standard is as follows:

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

The connector has eight grooves into which 8 twisted pair wires are laid according to the color scheme. The pinout is shown above.

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

Direct twisted pair connection by color

The first way is direct. The pinout of twisted pair 8 wires can be done both according to the 568 A standard (when one and the other ends of the wire are crimped according to the 568 A type) and according to the 568 V standard (when one and the other ends of the wire are crimped according to the 568 V type).

In our country, the 568 V method is common, and in the USA and Europe the 568 A type is most often used. The only difference between these two methods is the swapped white-green cores with white-orange and green with orange. Used to connect various user devices (computer, TV, laptop) to network equipment (switch, router, hub, router, patch cords, extender), and is also used to connect network devices among themselves. The information transfer speed with this scheme is 1 Gbit/s.

Direct twisted pair connection 100 Mb/s

In some cases, when high Internet speed is not required and large volumes of traffic are not provided, you can use a connection based on the colors of a twisted pair of 4 cores: white-red, red, white-emerald, emerald. This method saves wire consumption, but it must be taken into account that the highest information transfer speed drops 10 times and amounts to 100 Mb/s.

Twisted pair cross connection

The second method is cross or crossover. The 8-core twisted pair crimp (color scheme) is shown below, used to connect two computers into a home network without any network equipment or two client devices of the same type (computer, TV, laptop).

To make a crossover cable, you need to crimp one end of the wire according to the 568 A standard, and the other according to the 568 V standard. In this case, the wires are swapped: white-red with white-emerald, red with emerald. In this case, the information transfer speed will be only 100 Mbit/s. The Gigabit Crossover scheme involves exchanging places of all eight cores: white-red with white-emerald, red with emerald, blue with white-chocolate and white-blue with chocolate. This 8-wire twisted pair pinout color scheme is designed for high-speed 1000Base-T and 1000Base-TX networks when the information transfer rate is 1 Gbps.

To summarize, we can understand that if you need to connect a computer to the Internet, both ends of the cable should be crimped using the 568 V type. If you want to connect two computers to each other, then you should use the Gigabit Crossover circuit, where the first end of the wire is crimped using the 568 A type, and the other by swapping all eight wires.

How to crimp a network cable?

Now that you know how to correctly connect a twisted pair cable by color, you can begin crimping. How to do this is described below.

Tools and materials

Sequence of actions

Using two knives on the crimper, you can cut the cable to the desired length. Then remove 2 cm of outer insulation from both ends of the cable using a knife and the notch on the crimper located near the handles of the tool. This can also be done with a stripper or a sharp knife, but only carefully so as not to damage the core insulation.

Unwind the twisted pairs to make 8 separate wires. Lay out 8 wires in a row, according to the color scheme of the twisted pair pinout.

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

Insert the connector with the cable into the crimper socket marked 8P. Squeeze the handles firmly but smoothly until you hear a click. If you have a tool at hand, this procedure is quite simple, but if you don’t have pliers, you can get by with a flat-head screwdriver. To do this, you need to place the tip of a screwdriver on the connector contact and press until it cuts through the core insulation with its teeth. Do this for each of the eight contacts. Then you should also push through the central part of the connector body - the recess on the connector near the cable entrance, for fixation. If it doesn’t work the first time, you can cut off the failed connector and do it again.

Check the quality of work using a multimeter. To do this, you need to set the device to “resistance” mode. To check the device, connect the two probes to each other, it should show a resistance of 0 - this means there is contact. Then place one probe on the contact on one edge of the cable, and the other probe on the corresponding color contact on the other edge. If it shows 0, therefore, there is a connection, everything is fine. If it shows 1 or so, then the teeth have not broken through the insulation, you should either push the contacts again, or cut them off and do it again.

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

I’ll admit right away that I’m not an expert in crimping twisted pair cables, and I don’t have much experience in this matter, but I still know and can do something. More than once I had to make a network cable myself, and I even bought special pliers. In fact, there is nothing complicated about it. Anyone can crimp a twisted pair cable correctly. True, for this it is advisable to have a special tool - a crimper. And here small problems already arise. Most likely, you need to make a network cable of the required length once, and buying a crimper for this is not very correct. You will use it once, and most likely you will not need it again. And it doesn't cost a penny. There is an option to crimp the network cable without a special tool. For example, using a screwdriver. This is not very correct, but it is quite possible. It may well be an option to make a cable at home. I wrote about this in the article: . And in this instruction I will show you how to do everything using this very special tool.

As for the twisted pair cable itself, I talked about it in more detail in the article:. As you probably already understood from the title of the article, there I also wrote about the schemes by which you can make a network cable. It all depends on what purpose you need the cable for. We will return to this issue when we move directly to the manufacture of the cable.

What will you need to make a network cable?

Let's look at what materials and tools we need.

We've sorted out the set of materials and tools. Let's now choose the scheme by which we will crimp the network cable. This is a very important point.

Selecting a twisted pair crimping scheme

There are two schemes by which you can make a network cable. Let's find out which method is right for you.

I'm pretty sure you need a regular straight through cable. With which you can connect your computer, TV, game console to the router. Or, for example, it will connect two routers to each other.

Crimping a network cable (twisted pair) using a crimper

We've sorted out all the nuances; it's time to move on to the most interesting part. I will describe everything step by step, and of course show it in the photo.

It will turn out like this:

4 Check if the wires are positioned correctly in the connector. And are they fully inserted into the connector? 5 Insert the connector into the crimper and slowly crimp the cable while squeezing the handles. You need to squeeze the crimper handles tightly.

After crimping:

We crimp the other end of the cable in the same way. Our cable is ready, we can check it.

I connected my laptop to the router using this cable and everything worked. Maybe I didn’t perform the crimping of the twisted pair perfectly, of course you need to practice for this, but I did it. And this means that you will succeed too.

Without a special tool, a crimper, it is of course more difficult to crimp a network cable. The only difference is that after stripping, aligning, and installing the cable into the connector, you need something sharp (for example, a screwdriver) press each contact on the connector one by one.

If you still have questions about any points, then ask them in the comments.
