Fiber optic cable: The wire is made up of ultra-thin filaments of glass or plastic material, which is as thin as human hair, and it can carry beam of light. The glass fiber is covered with aramid yarn and plastic is covered strongly over it. Fiber optic cable is light based, which can carry information optically at the speed of light. Coaxial cable: Coaxial cable consists of center copper wire, a plastic wire is insulted over it, and then braided metal shield is grounded over it. The shield reduces electromagnetic interference and radio frequency interference; hence, it is used in computer networks and television cables. Coaxial cables can carry signals for wide range of frequencies, and hence, it is used for long-distance telephone communication.
