What Is a Coaxial Cable?
A coaxial cable is a specific type of cable that consists of four layers of material. There is an inner conductor, a dielectric insulating layer, another conductive layer, and an insulating layer. The cable is called coaxial because both the inner and outer conductive layers are on the same geometric axis. A geometric axis is a line passing through the length of the material. These cables are designed to be used for radio frequency transmissions. The purpose of the multiple layers is to restrict the electromagnetic field generated by the signal to interior of the cable itself. Using this development, the amount of electromagnetic interference through the cable is reduced. In a standard coaxial cable, the shield is formed from copper wire that is braided to improve flexibility. The braided wire can be silver-plated, double-layered or covered in foil to improve shield performance. Depending on the required level of signal shielding, the shield can be a solid metal tube. The materials used in the composition of the coaxial cable must comply with government regulations on the acceptable level of electromagnetic signal leakage. These signals interfere with a wide range of other signals. The type of insulation required to reduce the level of signal leakage to zero is both expensive and unpractical. The cables made today are a combination of features and are deigned to reduce the levels of interference as much as possible without incurring disproportionate costs and creating unpractical cable properties.
