Coaxial Cables

Coaxial cabling has a single copper conductor at its center, while a plastic layer provides insulation from the core and the braided metal shield that protects from outside interference. Although it is difficult to install, it is highly resistant to interference, and can support greater lengths between network enabled devices than twisted pair cables. There are two types of coax cables, thin coax (aka "thinnet") and thick coax (aka "thicknet).

Thinnet cables (see left) are 10base2, meaning they can reach speeds of 10 Mbps at a maximum segment length of 200 meters.

Thicknet Coax Cable

Thicknet cables (see right) are 10base5, and has an extra protective plastic cover that helps keep moisture away from the copper core, but makes it more difficult to install.

The most common type of connector that coax cables use is the Bayonne-Neill-Concelman (BNC) connector, which have different types of adapters available, such as a T-connector, barrel connector, and terminators.
