Cabling : Twisted Pair, Coaxial, Optical
The unshielded twisted pair (UTP) cable is used in many Ethernet networks. It has four pairs of wires that are housed inside of the lining of the cable. Each pair is twisted into several additional twists to prevent interference from other devices on the network. The structure of this type of cable increases its reliability and helps minimize network failures.
Coaxial cable is another common type of network cable. It has a copper conductor in its centre and a plastic coating serves as an insulator between the centre conductor and a metal shield. The cable is then covered with a coating. The coating may be think or thick — the thicker coating which less pliable provides extra protection.
An optical cable is an optical fibre that has been coated with a tough layer of resin. This layer is then surrounded by what is referred to as a jacket layer. Most often, the jacket layer is made of plastic. The layers around the optical fibre help provide the cable with extra strength. At the same time, these layers do not prevent the fibre inside from maintaining its properties.
The fibre in an optical cable is typically made of either glass or plastic. The fibre itself is thin and transparent, making it capable of transmitting light. One cable may have thousands of these fibres within it, making the cable capable of transmitting a great deal of information through bandwidth communication or large amounts of electricity.
