Coaxial Cable

coaxial line, transmission line used to transmit high frequency television telephone and telegraph signals

Coaxial cable is an electrical cable consisting of a round conducting wire, surrounded by an insulating spacer, surrounded by a cylindrical conducting sheath, usually surrounded by a final insulating layer (jacket). It is used as a high-frequency transmission line to carry a high-frequency or broadband signal. Because the electromagnetic field carrying the signal exists (ideally) only in the space between the inner and outer conductors, it cannot interfere with or suffer interference from external electromagnetic fields.

Noun
1. a transmission line for high-frequency signals
(synonym) coax, coax cable
(hypernym) cable, line, transmission line
(hyponym) ethernet cable

A cable consisting of a center conductor surrounded by an insulating material and a concentric outer conductor. (188 ) Note: Coaxial cable is used primarily for wideband, video, or rf applications.

<hardware> A kind of cable with a solid central conductor surrounded by insulator, in turn surrounded by a cylindrical shield woven from fine wires. It is used to carry high frequency signals such as video or radio. The shield is usually connected to electrical ground to reduce electrical interference.
