What is Coaxial Cable?


Definition – What does Coaxial Cable mean?

Coaxial Cable or Coax is a type of cable that has an inner conductor surrounded by the tubular insulating layer and surrounded by a tubular conducting shield. Most of the coaxial cables also have an insulating outer sheath or jacket. The cable is mostly used in a computer network and to deliver cable television services to end users. It was first commercially implemented in the early 1940s and is used for both broadband and baseband communication services.

Glossary Web explains Coaxial Cable

Coaxial Cable consists of four primary components such as core copper wire (primary channel), a dielectric plastic insulator (surrounds the copper), braided copper or aluminium sheath beneath the insulator (to protect external electromagnetic interference) and last layer (protect inner layer from physical damage).

The cable tends to carry signals at a greater distance and is a good choice for low signals, due to layered protection. Coaxial Cable has several types that are classified by the inner copper core diameter and number of protective sheaths.
