Coaxial cable is a type of electrical cable designed to transmit high-frequency signals with minimal interference and signal loss. It consists of a central conductor surrounded by insulating material, a metallic shield, and an outer protective jacket. Thanks to its unique construction, coaxial cable is widely used for television broadcasting, internet connections, telecommunications, security systems, radio frequency (RF) transmission, and data communication applications.
Even with the growth of fiber optics and wireless technologies, coaxial cables remain an essential part of modern communication infrastructure due to their reliability, durability, and cost-effectiveness.
A coaxial cable transmits electrical signals through its center conductor while the outer metallic shield protects the signal from electromagnetic interference (EMI) and radio frequency interference (RFI).
The cable structure typically includes:
Center conductor
Dielectric insulator
Metallic shield
Protective outer jacket
Because the conductor and shield share the same axis, the design is referred to as "coaxial," meaning "sharing the same axis."
This structure enables coaxial cables to carry high-frequency signals over relatively long distances while maintaining signal quality.
The center conductor is usually made of copper or copper-clad steel and serves as the primary pathway for signal transmission.
The insulating layer separates the conductor from the shield and helps maintain signal integrity.
The metallic shield protects against external interference and minimizes signal leakage.
The outer covering protects the cable from environmental damage, abrasion, and moisture.
