OPTICAL FIBER DEFINITION

 

Optical fibers is used as a medium for telecommunication and networking. Light in a fiber optic cable travels through a core by constantly bouncing from the cladding, a principle termed total internal reflection. As the cladding does not absorb any light from the core, light waves travel longer distances. Fibers with a sizable core diameter may be analyzed by geometrical optics. These fibers are called multi-mode fiber.
