Optical fiber: The working of an optical fiber is based on total internal reflection. Hence, option 2 is correct. Optical fibers consist of many long high-quality composite glass/quartz fibers. Each fiber consists of a core and cladding. The refractive index of the core (μ1) material is higher than that of the cladding (μ2).
18. Mention three advantages of optical fiber as waveguide over conventional metallic waveguide? 1. Optical fiber is made up of dielectric (glass) so there is no electromagnetic interference or cross talk. 2. Optical fiber cable is in small size with less weight. Hence it is flexible and it can be laid at any place without any congestion. 3.
