Coax cable, short for coaxial cable, is made up of four layers, one of which is shielded by a metallic shield. The cable's shielding helps to keep outside electromagnetic interference at bay. Coax cable is noted for its excellent heat resistance, ease of installation, and ability to transport high-speed data over long distances.
Coax cables are excellent for transferring data for older analogue CCTV cameras, radio frequency, TV, internet, and other audio/visual devices.
