Answer / Sri Ram Yadav
Optical Fibers are thin, flexible, and transparent materials used for transmitting data in the form of light signals. They consist of a core made of glass or plastic surrounded by a cladding material with a lower refractive index. The light signal is guided through total internal reflection within the fiber. Optical fibers provide high bandwidth, immunity to electromagnetic interference, and low attenuation compared to traditional copper wires. They are commonly used for long-distance telecommunications networks, cable television, and internet connections.
