Copper cabling cat. 5th UTP

At PH-EL and security, we carry out all kinds of data installations.

Copper cabling cat. 5e was previously the most widely used type of data cabling, but as a growing need for larger data transfers, Kat is used. 5th UTP today only smaller networks.

Cat. Therefore, 5th installations are only suitable for installations from 10-100 megabits. If data is to be transmitted at greater speed, cat must be used. 6 or higher which is usable for gigabit installations.


Unshielded Twisted Pair, abbreviated UTP, is the most common form of cable found in local area networks. It is one of the cable types recommended for Ethernet. Ethernet is the most widely implemented set of standards for the physical properties of networks, including the cable type used to create the cable.

Of the cable types Ethernet recommends, UTP is the cheapest, which explains its popularity.

The UTP cable contains eight wires arranged as four pairs. The two wires in each pair represent the positive and negative paths of a complete circuit and they are twisted around each other to the length of the cable.


Some cables contain a metal shield under the outer plastic of the cable. This screen protects against environmental magnetic interference. When a current moves along a wire, it creates a magnetic field around this wire. Incoming radiation merges with either positive or negative wire according to its polarity. Twisting together of these two wires brings their magnetic fields into contact. The opposite polarities of the two fields make them equalize, merging environmental magnetic radiation with them.
