Coaxial cable:-With ``coax'', the medium consists of a copper core surrounded by insulating material and a braided outer conductor.Coaxial cable carries signals of higher frequency ranges than those in twisted-pair cable.
Coax has a central core conductor of solid or stranded wire (usually copper) enclosed in an insulating sheath, which is, in turn, encased in an outer conductor of metal foil, braid, or a combination of the two.The outer metallic wrapping serves both as a shield against noise and as the second conductor, which completes the circuit. This outer conductor is also enclosed in an insulating sheath, and the whole cable is
protected by a plastic cover.
Characteristics:-
*)Co-axial cable has superior frequency characteristics compared to twisted-pair and can be used for both analog and digital signaling.
*)Coaxial cables are used both for base band and broadband communication.
*)This cable offers bandwidths of 300 to 400 MHz facilitating high-speed data communication with low bit-error rate.
*) In broadband signaling, signal propagates only in one direction, in contrast to propagation in both directions in base band signaling.
Applications:-
*)Coaxial cable was widely used in analog telephone networks where a single coaxial network could carry 10,000 voice signals.
*)the most popular use of co-axial cable is in cable TV (CATV) for the distribution of TV signals.
*)coaxial cable is used in traditional Ethernet LAN s.
