Coaxial cable is used to carry television signals and connect video equipment together. It is also used to carry radio signals and connect receivers, transmitters, and antennas together. Short lengths of coaxial cables are also used for connecting devices with test equipment, like signal generators. Coaxial cable was once widely used for connecting computer in local area networks (LANs) but has been replaced by twisted-pair cable. However, cable broadband remains popular and uses the same coaxial cable that cable television uses. Most coaxial cable networks will eventually be replaced by superior fiber optic networks.
