Coaxial Cables

Coaxial cable, also known as coax, was the foundation fo LAN in the 1980´s. It consists of a central copper core surrounded by an insulator, which is covered by a braided wire and metal foil. A final layer of insulator covers the braided wire. Figure shows a coaxial cable and its different layers. Nowadays two types of coaxial cables are available in the market.

Thinnet is a flexible coaxial cable and is used for short distance communications. A British Naval Connector (BNC) is used to connect the thinnet to the network adapter.

Thicknet is a thicker cable than the thinnet and supports data transfer over a longer distance. The thinnet cable usually uses a Vampire tap to connect to a transceiver, which uses a drop-cable to connect to the adapter unit interface (AUI).
