What is Fiber Optics? Understand its Concept and Advantages

An optical fiber is basically composed of dielectric material (generally silica), according to a cylindrical structure, transparent and flexible, of microscopic dimensions, comparable to a human hair. The basic cylindrical structure of the optical fiber is formed by a central region, called core, surrounded by a layer, also of dielectric material, called shell. The fiber optic shell composition, with slightly lower refractive index material than the core, provides conditions for the propagation Read more [...]
