In the modern period, when the Internet is in each apartment, any user should know how to properly lay the wires. At the very least, a person should be able to do this in his apartment in order to thereby be able to create a connection to the world wide web without any help. Naturally, after just laying the Internet cable you will not appear, because you did not connect it directly to the network card. To do this, you must have a specific connector. It should be fixed at the end of the wire, the result should be twisted pair.
However, to do this without the help of special devices will not work, because the device must be compressed. But there is a simpler option - go to the store and buy there is already ready cable "twisted pair". But in this case, you will have to pay for it in 5, or even 10 times the large amount. Therefore, if you want to save money, then try to make the cable "twisted pair" yourself.
The name of this cable was not accidental. It presents 8 copper conductors, which are distributed in pairs. These postings are arranged in a twisted form and have approximately the same color. Let's say it can be orange and white-orange, blue and white-blue, etc. Given that they are arranged in a pair and twisted, they decided to call them a twisted pair.

What are 8 wires for?
It should be said that this version of the execution was made for the future. Even at that moment, when the high-speed Internet was just beginning to be distributed, such cables were often used in internal networks. In other words, with their help, two or more computers were connected or connected to the router, thereby creating a common network. At that time, all wires had only 4 wires. These cables represented a 100 megabit network, which was characterized by a high data transfer rate at that time.
However, gradually began to create more high-speed cables, and therefore today everyone has the opportunity to make a network with a data transfer rate of up to 1 gigabit per second. Such a possibility is provided for any modern network card, regardless of whether it is built-in or separate. And to create so much high-speed network, we must have a cable with eight wires or 4 twisted pairs.
For this reason, it is advisable to crimp all eight wires, if you have purchased just such a cable. However, you can also find special cables, which have only 4 wires.
What do you need to snap?
If you decide to independently compress the twisted pair, then you must first have the wire itself. When choosing it, be guided by that the speed that will suit you: A wire with 4 conductors can provide data transmission at a speed of 100 megabits per second, and a cable with eight conductors - 1 gigabit. At the same time there is an important point: the cable to be purchased must be special, designed for creating networks and the Internet.
To date, they are made in 2 versions:
- STP cables. They represent a class of shielded cables, which have a fairly high price and are not the only option for laying networks in an apartment.
- UTP. These cables represent an unshielded class. They are most often used in various rooms. Demonstrating high practicality, they are on top of everything and affordable.
In the framework of UTP cables, you can select several subcategories: 3, 5, 6 and 7. Choosing category 3, you get the cheapest and not very high-quality twisted pair, since it has thin conductors that will not serve for a long time. Twisted pair, belonging to category 7, has the highest durability and reliability, however, due to the high price, it cannot be considered the best option. The best choice among those available today is the 5th category, which not only has an affordable price, but also has a fairly good quality of performance. Today, the vast majority of organizations use this cable, which will suit any consumer in all respects.
RJ-45 connector. This is a standard connector with which network devices are connected. It will be he who will be used by us to fasten it on the veins that have been stripped of insulation.
Crimp tool. As it comes a simple penknife. Also need and special scissors, called ticks.
Special tool. Frankly, use it as an ordinary user is optional. However, if you set yourself the task of making a twisted pair according to all the rules, then you will have to prepare it.
Many often wonder what is the use of ticks if this operation can be performed with scissors. In part, they are right, since they can also be compressed. However, ask yourself, can you with this option of crimping to ensure the effective operation of the cable? You will be able to achieve this, provided you acquire the simplest ticks. And for them you will have to pay no more than 200 rubles.
How to combine colors?
In principle, this is nothing complicated. Today there is two types of connection:
- standard T568A;
- standard T568B.
To make it easier to deal with them, you need to remember the following: the first is white-orange and orange, and the second is white-green and green.
Frankly, in our country the 2 most popular option. However, if you create an internal network, you can compress the cable in the way you like.
Crimped twisted pair 8 cores
Let us dwell on how to crimp the 8 wires when creating a network with a speed of 1 gigabit. Given that today the demand for more high-speed networks for the Internet is increasing, it is this type of crimping that is the most popular.
Network cable crimping process
First you must remove the insulation at the end of the cable so that it was trimmed to 3 cm.
Further, in accordance with the pinout pattern, all the cores should be carefully stranded from each other so that they are placed separately.
Next, we will perform manipulations with the RJ-45 connector: we will have to insert the wires, but first they should just put without crimping, in order to find out that each of the canals is high quality, and the wires go in before the end.
When it comes time to insert the wires into the connector, it will not hurt you to focus on the contact group. For traditional connectors, pin assignments and colors has the following scheme:
- The first is white and orange;
- The second is orange;
- The third is white and green;
- The fourth is Blue;
- The fifth is white and blue;
- The sixth is green;
- The seventh is white-brown;
- The eighth is brown.
After we have inserted all the wires, according to the pinout scheme, you should make sure that they are entered to the very end. If everything is done correctly, you can proceed to crimping.
The cable with a bare end of 3 cm, we must cut. Performing such a manipulation, we will ensure that the wire will be securely fastened and will not move. This opportunity provides RJ-45 connector design, which has a special knob fixing the winding.
When the twisted pair will be cut, you need to put the wires in the connector, after which we put all this construction into the tongs. You will easily understand exactly where you need to place the cable, because the clamp has a special connector that fits only in one position. After that, you just need to press on the tool, and the task will be solved.
If you want to create a connection for the Internet, then you need to connect a special wire - twisted pair. If you wish, you can buy a finished cable or bring it to your own mind, and for this you have to compress it. Make it quite simple, if you follow all the rules. The main thing here is to make sure that you have correctly inserted the wires, and you can easily cope with the rest.
