Fiber optics is a method of data transmission that consists of sending encoded information through a beam of light projected through a glass tube or pipe. It has its origins in the work of 19th-century scientists Jean-Daniel Colladon (a Swiss physicist who discovered that a continuous ray of light could shine through a water pipe through internal reflection) and John Tyndall (a physicist Irishman who formally demonstrated internal reflection to the Royal Society in London by illuminating the stream from a jug of water.)
AND HOW DO FIBER OPTIC CABLES WORK?
Fiber optic cables are made of very thin strands of glass or plastic, each of which is less than a tenth the thickness of a human hair.
