Coaxial Cabling
Coaxial cable consists of a solid inner core, usually copper, or wire strand conductor that is surrounded by insulation.
Just outside of the insulation is a shield, which is a foil or copper braid that protects the inner conductor.
A protective jacket surrounds the outside of the cable.
Coaxial cable supports data transmission rates of 10 Mbps. The two most commonly used types of coaxial cable are thicknet and thinnet.
Thicknet is a thicker form of coaxial cable than thinnet. Thicknet segments can be up to 500 meters long while thinnet segments are limited to 185 meters.
