What is Coaxial Cables?
Coaxial cable is a type of communication cable in which a solid center conductor is surrounded by an insulating dielectric which in turn is surrounded by an outer conductor (usually a braid, foil or both). The entire cable may be rigid or flexible. Rigid types have a solid sheath, while flexible types have a braided sheath, usually of thin copper wire. The solid center conductor, also called the dielectric, has a significant effect on the cable’s properties, such as its characteristic impedance and its attenuation. The dielectric may be solid or perforated with air spaces. Connections to the ends of coaxial cables are usually made with RF connectors. Coaxial cables have a wide bandwidth and are capable of carrying many data, voice, and video conversations simultaneously.
