Answer:
Telephones are an important invention that have the ability to connect people all over the world. They consist of numerous pairs of copper insulated wires having a diameter that ranges from 0.3 to 0.9 and are either twisted into two or four pairs. These pairs of wires are then connected to each phone jack in your house. There are many different cables that serve different purposes and vary in configuration, size and performance. Here are the most common types of telephone cables.
1. Coaxial cable
One of the most common telephone cables is called the coaxial cable. It is called coaxial because it has one physical channel, which is an insulated layer that is a woven shield of copper. This inner layer carries the signal and is surrounded by another physical channel that is created out of a plastic sheath. The outer channel is considered the ‘ground’ where many of the pairs of coaxial tubes are placed and transmit information over a great distance. It is essential that you take proper precautions to maintain your home electrical wire to ensure they are in perfect working condition. Coaxial cables come in many different sizes and have various performance and power-handling capabilities. In addition to serving as a telecommunication connection, they can also be used to connect audio and video equipment, LAN and television networks. A few coaxial cables include twin-axial, bi-axial and RG/6 cables.
