So who invented optical fiber? Researchers Robert maurer, Donald Keck and peter schulz of Corning Glass Company invented optical fiber.
1854, John Tindal proved to the Royal Society that light can be conducted through a curved water flow, and he thus proved that light signals can be completely curved; 1880, Alexander Graham Bell invented his optical telephone, which used light beams to transmit sound signals. Due to the influence of the weather, Bell stopped further research on this invention. In 1880, william wyler invented a light pipe system lined with highly reflective coating. This system can be placed in the basement. The light emitted by the arc lamp illuminates the family, and the light is guided around the extended family through the conduit.
1895, French engineer Henry designed a curved glass amplifier system to guide light images on early TV. 1930 the first german medical student to assemble a bundle of optical fibers to carry images transmitted the images of light bulbs in his experimental report, but the image quality was poor. 196 1 year, Elias of American optical company published the theoretical description of single-mode fiber. His core is very small and can only carry one waveguide mode of light. Finally ushered in great progress! 1964, Dr. Gao Kun determined an important long-term standard communication equipment, the specification of which is the optical loss per kilometer 10 or 20 decibels, so the optical fiber standard was established. Dr Gao Kun also explained that a purer glass is needed to help reduce the loss of light. ? 1970, Robert, Keck and Schultz invented the optical fiber line, which transmitted 65,000 times the signal of copper wire, and solved the problem raised by Dr. Gao. ? By the end of this century, more than 80% of the world's long-distance communications will be carried out through optical cables and 25 million kilometers of optical cables.
The application of optical fiber in communication, the communication networks all over the world are connected by optical fiber, and now we make phone calls with others, and the video benefits from optical fiber!
