A type of cable that was once popular for Ethernet networks is coaxial cable, sometimes called thinnet or BNC cable because of the type of connectors used on each end of the cable. It was the original cable used in Ethernet networks and is still used almost universally for television connections. There are two types of coax cabling: Thinnet and Thicknet. The two differ in thickness and maximum cable distance that the signal can travel.
Thinnet: Thin coaxial cabling, known as RG 58, (which is a flexible coaxial cable about ¼-inch thick.) is used for connections that use a low power signal. In Ethernet, the maximum distance that data can be transmitted Is 185 meters.
Thicknet: This coaxial cable, also known as RG-8, gets its name by being a thicker cable than thinnet. Thicknet cable is about ½-inch thick and is used for connections that require a higher power signal. The maximum travel distance between nodes using thick coaxial cables is 500 meters.
