This is for the reason that in contrast to copper wires, optic fibre wires are less heavy, carry more data and are more flexible. When light travelling in an optically dense medium hits a boundary at a steep angle (larger than the critical angle for the boundary), the light is completely reflected. In an optical fiber, the light travels through the core (m1, high index of refraction) by constantly reflecting from the cladding (m2, lower index of refraction) because the angle of the light is always greater than the critical angle. The communication using optical fiber cable can be a technique of transmitting data from one location to another by transmitting light pulses.
