What are coaxial cables and how do they work?
Coaxial cables are a type of transmission line that consists of a central copper wire surrounded by an insulating material, a braided or foil shield, and an outer jacket. This design allows coaxial cables to transmit data and signals over long distances with minimal interference and signal loss. The central copper wire carries the signal, while the shield acts as a barrier to prevent electromagnetic interference (EMI) from affecting the signal. This design makes coaxial cables ideal for a wide range of applications, including television broadcasting, internet connectivity, and telecommunications.
The working principle of coaxial cables is based on the concept of electromagnetic induction. When an electrical signal is applied to the central copper wire, it generates a magnetic field that induces a voltage in the wire. The shield surrounding the wire helps to contain the magnetic field and prevent it from radiating outward, which reduces EMI and signal loss. As a result, coaxial cables can transmit high-frequency signals over long distances with high fidelity and minimal degradation. This makes them an essential component in many modern technologies, including cable television, broadband internet, and wireless communication systems.
