How Does Fiber Optics Trasmit Information With Light?
Fiber optics are widely used in fiber telecommunication systems which allows the transmission of data over longer distances since it carries a higher bandwidth to homes and offices. The message is sent through thread-like glass fibers using ultra-fast pulses of light. Even though fibers can be made out of translucent plastic, glass, or a combination of the two, but due to the lower optical attenuation, the fiber used in long-distance telecommunications applications are always glass. Generally, cable TV shows, phone calls, or Internet files travel through copper wire cables in the form of electrical signals. However in a fiber system, a transmitter converts these electrical signals into pulses of light which travel along the length of the fiber optic cable until they reach at the end of the line. The receiving end then re-converts the light pulses to electrical signals to turn them back into voice, video, and data files. But how does an ultra-thin thread of glass carry so much informati
