Fiber Optics

Fiber optics is a technology used to transmit the facts such as light or pulses with fiber or plastic over long distances. Visual fibers are about the width of a human hair strand and, when tied directly to a fiber-optic cable, can transmit multiple long-distance records and faster in different ways.
