Definition

Coaxial cable is a type of cable used to transmit telephone, television, and computer signals. It features a central conductor surrounded by a tubular insulating layer, a metallic shield, and an outer insulating layer.

Purpose

Coaxial cables are designed for high-frequency signal transmission with minimal signal loss and electromagnetic interference. They are widely used in telecommunications and broadcast systems.

Examples of Use

  1. Cable Television: Used to deliver TV signals from the service provider to the customer's home.
  2. Internet Connections: Utilized in broadband internet connections to transmit data.
  3. Telephone Lines: Employed in older telephone networks for signal transmission.

Related Terms

  • Fiber Optic Cable: A cable that uses light to transmit data, often used in high-speed internet connections.
  • Twisted Pair Cable: A type of cabling that features pairs of wires twisted together to reduce electromagnetic interference.
  • Signal Attenuation: The loss of signal strength as it travels through a cable.

Notes

Coaxial cables are known for their durability and ability to carry signals over long distances without significant loss. Proper installation is crucial to maintain signal quality and avoid interference.
