Advantages of Coaxial Cable
Coaxial cable is a type of cable that has an inner conductor surrounded by a tubular insulating layer and a tubular conducting shield. Many coaxial cables also have an insulating outer sheath or jacket. Coaxial cable differs from other shielded cable used for carrying lower-frequency signals, in that the dimensions of the cable are controlled to give a precise, constant conductor spacing, which is needed to function efficiently.
Coaxial cables are advantageous because they support multiple channels and have a high bandwidth and low error rates. Coaxial cables are suitable for long distances, and they are available in multiple sizes. They can support many services, including multimedia, video, data and voice. In coaxial cable transmission, each channel has a high capacity, depending on the location of the service. A coaxial cable has a shielded copper wire, which safeguards against electric noise in a network, leading to lower error rates. Coaxial cable technology has been present for many years in data communication, and a coaxial cable costs less than a fiber-optic cable.
