Coaxial cable, also known as coaxial, is used to transmit radio frequency (RF) signals. It has low emission losses and provides protection against electromagnetic interference, allowing the low power consumption of the signal to be transmitted over longer distances. A coaxial cable consists of a core, insulation, shielding, and casing. This is what is called coaxial cable, because these chapters all have the same axis. There are many different types of coaxial cables, each designed with different physical and electronic characteristics for specific tasks. This is commonly used to execute cable TV signals along suburban streets and homes.
Coaxial cables are used to transmit television signals and connect video devices together. It can also be used for radio signals and connecting receivers, transmitters, and antennas together. Short length coaxial cables are also used to connect equipment and testing equipment, such as signal generators. Coaxial cables were once widely used to connect computer local area networks (LANs), but have replaced twisted pair cables. However, wired broadband is still popular and uses the same coaxial cable for the purpose of cable television networks. Most coaxial cable networks will eventually replace fiber optic networks.
