CO-AXIAL CABLES
Coaxial cables, often called "coax," are a type of electrical cable designed to transmit high-frequency signals with minimal interference. They consist of a central conductor, an insulating layer, a metal shield, and an outer insulating layer, all concentric around a central axis. This structure helps to confine the signal and prevent it from being affected by external noise. Here's a more detailed breakdown: • Central Conductor: This is the core of the cable, usually made of copper, which carries the electrical signal. • Insulating Layer (Dielectric): This layer surrounds the central conductor and provides electrical insulation, preventing signal loss and maintaining signal integrity. • Metal Shield: This layer, often made of braided copper or aluminum, acts as a shield against external interference, such as electromagnetic radiation. • Outer Insulating Layer (Jacket): This provides physical protection for the cable and helps to prevent damage. Coaxial cables are widely used for various applications, including: • Cable TV: Connecting cable boxes to televisions. • Satellite TV: Connecting satellite dishes to receivers. • Networking: Some older Ethernet networks used coaxial cables for data transmission. • Telecommunications: Transmitting signals in various telecommunications systems.
