A dielectric layer, made up of an insulating material with very well-defined electrical characteristics, surrounds the wire. The center conductor layer is a thin conducting wire, either solid or braided copper. This construction ensures signals are enclosed within the cable and prevents electrical noise from interfering with the signal. How coaxial cables workĬoaxial cables have concentric layers of electrical conductors and insulating material. Depending on the carrier technology used and other factors, twisted pair copper wire and optical fiber are alternatives to coaxial cable. AT&T established its first cross-continental coaxial transmission system in 1940. Many of these cables or pairs of coaxial tubes can be placed in a single outer sheathing and, with repeaters, can carry information for a great distance.Ĭoaxial cable was invented in 1880 by English engineer and mathematician Oliver Heaviside, who patented the invention and design that same year.

Some homes and offices use coaxial cable, too, but its widespread use as an Ethernet connectivity medium in enterprises and data centers has been supplanted by the deployment of twisted pair cabling.Ĭoaxial cable received its name because it includes one physical channel that carries the signal surrounded - after a layer of insulation - by another concentric physical channel, both running along the same axis. It is also sometimes used by telephone companies to connect central offices to telephone poles near customers.

It is primarily used by cable TV companies to connect their satellite antenna facilities to customer homes and businesses. Eamon McCarthy Earls, Global North InstituteĬoaxial cable is a type of copper cable specially built with a metal shield and other components engineered to block signal interference.
