Coaxial cable, is a type of electrical cable that has an inner
conductor surrounded by a tubular insulating layer, surrounded
by a tubular conducting shield. Many coaxial cables also have
an insulating outer sheath or jacket. The term coaxial comes from
the inner conductor and the outer shield sharing a geometric
axis. Coaxial cable was invented by English engineer and
mathematician Oliver Heaviside, who patented the design in 1880.
[1]Coaxial cable is a type of transmission line, used to carry
high frequency electrical signals with low losses. It is used in
such applications as telephone trunklines, broadband internet
networking cables, high speed computer data busses, carrying cable
television signals, and connecting radio transmitters and receivers
to their antennas. It differs from other shielded cables because
the dimensions of the cable and connectors are controlled to give
a precise, constant conductor spacing, which is needed for it
to function efficiently as a transmission line.
