The history of the fiber optic By Brandon Leung

Origins It all started back in roman times The first fiber optic was created back in 1790’s Created by The Chappe Brothers They created the “optical telegraph”

Develpoment Optical communication dates back to the 1790’s to the optical semaphore telegraph invented by French inventor Claude Chappe. In 1880 Alexander Graham Bell patented an optical telephone system called the photophone but I was not as practical as his earlier invention the telephone. during the 1920’s John Logie Baird in England Clarence W. Hansell in the United States patented the idea of using array of hollow pipes or transportation rods to transmit images for television or facsimile systems 1954 Dutch scientist Abraham Van Heel thought of the idea of cladding the fiber optic which greatly reduce interference between other fiber optic cables

Function Fiber optics function is not like wireless and like wires the go through the wall it work’s by sending code that travel by light down glass or plastic pipes originally develop for endoscopes in the 1950 to help doctors see in the human body before they have to cut it open but in the 1960 engeeners use the same technology to send telephone calls at the speed of light

How it works Light travels down the wire bouncing off the walls Usually light would just escape the glass tube but when the glass tube is tilled at an really shallow angle something less the 42 degrees the light would bounce off the glass like a mirror this is called total internal reflection this is one of keeping the light in the tube

The future of the fiber optic They are trying to improve the laser for a shorter wave length
