Twisted pair cable:

Twisted-pair network cables are used to transfer data to network systems. History of twisted cables (TP) goes back to 1970 and the time of the invention of the telephone. This type of cable has played an important and influential role in the history of human communication.

 Twisted-pair network cable consist of a number of twisted-pair pairs with spiral insulation. The most prestigious brands in this field are Legrand Network Cable, Nansense Network Cable, Schneider Network Cable, Balden Network Cable and more.

Commonly used network cables today consist of two or four pairs of twisted wires. In the 1990s, these cables were recognized as the standard for Ethernet cabling and were initially used as CAT3 cables at speeds of 10 Mbps.

Subsequently, improved versions of the CAT5 and CAT5e cables were able to increase the data transfer rate by up to 1000 Mbps. Today, improved versions of network cables include CAT6, CAT6A, CAT7 and CAT8.

The letter A stands for Augmented meaning completed. The reason for using this name in some types of network cable is the greater bandwidth of that cable.

The twisted-pair network cables are divided into two categories: Shieldless and Foil (UTP) and Shielded and Foil (SFTP). However, more fuel-efficient models are also available in the market with the names FTP (foil-free shield) and STP (foil-free shield).

UTP cables include twisted pair with a plastic layer and are more widely used in Ethernet networks because of their lower cost. UTP cables are categorized into different types depending on the thickness of the wires used and the quality of data transmission on them, with the CAT letters of the word Category meaning to name these cables.

CAT1 cables are mainly used for voice transmission at a maximum speed of 1 Mbps and CAT2 cables for voice and data transmission at a maximum speed of 4 Mbps. CAT3 cables are used to transmit data at a maximum speed of 10 Mbps.

 CAT5 cables are used to transmit data at a speed of up to 150 Mbps. There is, of course, some fifth-class cables that are used to transmit data at up to gigabits per second (1000 Mbps) and are called CAT5e cables.

The letter e is derived from the word Enhanced in the sense of improved. CAT6 cables also have a transmission speed of 1000 Mbps and CAT6A cables have a transmission speed of 10,000 Mbps.

CAT5e and CAT6 cables are nowadays regarded as the most widely used cables in the network domain. CAT7 cables are only used for shielded cables and support high-speed transmission up to 10,000 Mbps.

 CAT8 cables are now available in the market today with amazing speeds and unparalleled 2 GHz bandwidth.

Laminated cables (SFTPs), like UTP cables, are made of twisted copper wire with an aluminum foil cladding, which prevents electromagnetic interference but in turn lowers the cost of the cable.

It also increases. Remarkably, in the case of network cables, the coatings on these conductors are twisted.

 Most of these cables are PVC laminated but sometimes LSZH lined cables are also available in the market. The abbreviated LSZH for Low Smoke Zero Halogen means halogen-free cables.

That is, these types of cables do not produce toxic smoke when burning.

 The older generation network cables with RJ45 socket and CAT7 and CAT8 network cables with GG45 socket are connected to other network equipment. The most important and most used of these equipment are patch panels and patch cords .

The network patch panel has different ports and as a switch, it is widely used in network systems. The network patch, or LAN cable, also has different sockets with two sockets that can be used to connect different systems to the network.

UTP and SFTP network cables are widely used today because of their high transmission speed,

good long-distance data quality, relatively low cost and easy cabling.

 Outdoor network cables are also used when network cabling needs to be done in the open.
