What is copper cable in telecommunication? In general, the basic unit of a copper telecommunication cable is made of two insulated conductors, twisted together, with a constant lay length in order to create a balanced circuit. One may also group 4 conductors, twisted together, forming a quad which may contain, within itself, two or three transmission circuits.
Why is copper used in telecommunications? Copper is the metal that has been traditionally used for communications wires and cables. It is ductile, has suitable tensile strength and is a very satisfactory conductor. As a conductor it is second only to silver and if the conductivity of silver is 100 units then pure copper would measure 97 units.
