What Are the Advantages and Disadvantages of Coaxial Cable?


Quick Answer

Coaxial cables are advantageous because they support multiple channels and have a high bandwidth and low error rates. However, they are disadvantageous because they are susceptible to security risks, damage, congestion and noise, and they are costly to install.

Coaxial cables are suitable for long distances, and they are available in multiple sizes. Using coaxial cables instead of twisted-pair cables increases network distance by 500 meters. Coaxial cables 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. A coaxial cable costs less than a fiber-optic cable. However, coaxial cables are susceptible to electromagnetic and radio frequency interference and may transfer noise between components of a network. If lightning strikes a coaxial cable, it conducts it and burns equipment at its end. Coaxial cables lose signal in long distances, but they are suitable for home use. Individuals should consider the size of a coaxial cable because it is difficult to work with thick cables and pass them through existing troughs and conduits that are limited in size.
