What is an FTP cable where it is used

Every day the Internet network acquires more and more new users. Almost all of the world needs its services, connecting using various methods. One of the most popular types of connection organization is FTP 5E cable, which is often called "twisted pair".

Its application in practically all large wired networks is explained by the fact that with its high quality work and stable transmission of the signal it has a fairly low price, which allows many Internet providers to connect their subscribers completely free of charge, not charging a fee even for equipment. This made such a cable (twisted pair of FTP) the most used and popular material for organizing communications.

Usually it consists of eight strands twisted together in pairs. More precisely, inside the polyethylene braid of the cable, you can find four pairs of strands twisted together. Each separate wire is enclosed in its own braid of polyethylene. It also has a special protection against wandering currents and other electromagnetic interference that can occur in electrical circuits and have a negative impact on the communication conductors. That's why the FTP cable has twisted pairs.

The fact is that it is not possible to completely get rid of the influence of the electromagnetic field , so the pairs of wires are wired so that this effect is on them evenly, there is no difference in potentials. Thus, this cable can provide a stable connection without interference.

To date, there are other conductors for establishing a stable connection to the Internet, but FTP 5E cable is considered the most optimal. It has a low price (unlike other, better quality materials) and can satisfy the need for data transfer speed of almost any user without special requests. Also, it has good technical characteristics, allowing it to bend, fold and hold even in the most uncomfortable places.

For ease of installation, all wires that have an FTP cable are marked with a separate color. Each pair has its own marker, but since the two wires can not be the same, the second one is painted half, leaving the untouched part white. Therefore, removing the upper braid, you can see blue and blue-white, orange and orange-white, brown and brown-white, green and green-white wires.

There are special crimp schemes where each wire that has an FTP cable is intended for a specific location (according to its color). This greatly helps in the installation and subsequent maintenance, because the installer knows exactly what the specific wire is responsible for, what functions are assigned to it. But you can connect them in any sequence, the main thing is that both ends of the cable correspond to the same socket on both devices. Color marking is given only for reasons of standardization of all networks, and the wires themselves are completely identical, regardless of the color they are labeled.
