Coaxial cable, often referred to as coax, is a type of electrical cable consisting of an inner conductor surrounded by a cylindrical conductor, with the two separated by an insulating layer. Used to transmit radio frequency signals, coax cable is commonly employed in telecommunications, computer networks, and cable television systems.
Coax cable offers several advantages over other types of cables, including its ability to transmit signals over long distances with minimal loss, its high bandwidth capacity, and its resistance to electromagnetic interference. Due to these advantages, coax cable has been widely used in various applications, from connecting home entertainment systems to transmitting data across long distances in telecommunication networks.
