Coaxial cable is made up of a copper wire surrounded by an insulation layer, an extruded metal tube, or a grounded braided wire shield, the whole thing wrapped in another insulation layer, and finally a protective outer layer. Metal tubes have a high transmission capacity but are only used in certain applications due to their rigidity. End connections for coaxial cables are typically made up of specially designed radio frequency (RF) connectors. Coaxial cables are used in distributed networks to transfer radio frequency, internet, and video data.
This cable, also known as coax, is commonly used by television companies to transport television broadcast signals in customer premises and by customers to connect television receivers to an external antenna. There are short coaxial cables available for use in ham radio systems and to connect home video equipment. Coaxial cable is commonly used in computer networks such as Ethernet. Coaxial cable has a speed range of 10 to 100 Mbps and is relatively inexpensive.
Increasing North American telecom and IT spending, low installation costs, and technological advancements in coaxial cables and related equipment for enabling reliable data transfer are expected to be major drivers for the North American coaxial cable market. Previously, coaxial cable was widely used in LANs; however, optical fiber cable, twisted-pair wiring, and radio waves are now widely used in LANs due to their various benefits such as lower cost, greater capacity, and ease of use.
