Who invented fiber optics cable

The following timeline highlights the key dates and developments. John Tyndall demonstrated to the Royal Society that light could be conducted through a curved stream of water, proving that a light signal could be bent. Alexander Graham Bell invented his " Photophone ," which transmitted a voice signal on a beam of light. Bell focused sunlight with a mirror and then talked into a mechanism that vibrated the mirror.

At the receiving end, a detector picked up the vibrating beam and decoded it back into a voice the same way a phone did with electrical signals. However, many things — a cloudy day, for instance — could interfere with the Photophone, causing Bell to stop any further research with this invention.

William Wheeler invented a system of light pipes lined with a highly reflective coating that illuminated homes by using light from an electric arc lamp placed in the basement and directing the light around the home with the pipes. The medical team of Roth and Reuss of Vienna used bent glass rods to illuminate body cavities.

French engineer Henry Saint-Rene designed a system of bent glass rods for guiding light images in an attempt at early television. American David Smith applied for a patent on a bent glass rod device to be used as a surgical lamp. Hansell patented the idea of using arrays of transparent rods to transmit images for television and facsimiles respectively. German medical student Heinrich Lamm was the first person to assemble a bundle of optical fibers to carry an image.

Lamm's goal was to look inside inaccessible parts of the body. During his experiments, he reported transmitting the image of a light bulb. The image was of poor quality, however. His effort to file a patent was denied because of Hansell's British patent. Hopkins separately wrote papers on imaging bundles. Hopkins reported on imaging bundles of unclad fibers while Van Heel reported on simple bundles of clad fibers. He covered a bare fiber with a transparent cladding of a lower refractive index.

This protected the fiber reflection surface from outside distortion and greatly reduced interference between fibers. At the time, the greatest obstacle to a viable use of fiber optics was in achieving the lowest signal light loss.

Elias Snitzer of American Optical published a theoretical description of single-mode fibers, a fiber with a core so small it could carry light with only one waveguide mode. Snitzer's idea was okay for a medical instrument looking inside the human, but the fiber had a light loss of one decibel per meter. Kapany has brought about a major development with the introduction of fiber optics.

The fiber-optic communication has created a special place among these new inventions. In this rapidly globalizing world, it has fundamentally facilitated and steered the fiber- optic communication working which has brought about a revolutionary change today.

With the introduction of fiber optics, there has been a radical shift in the traditional industry to an information-empowered society. The man behind this cutting-edge technology Dr. Narinder Singh Kapany is one of the most notable personalities of today. He has transformed and modernized the way information is communicated and transmitted in every sphere of life. Who Invented Fiber Optics. Inventor of fiber optics Narinder Singh Kapany.

In simpler terms? And in doing so, long-distance information transfer soon transitioned from copper wires to fused silica. Further, Kao predicted in that world's oceans would be filled with fiber optics. And this was several years before such a trans-oceanic fiber-optic cable became serviceable. It's no wonder he was awarded the Nobel Prize in Physics in By Paul Brodsky.

And fiber optics grew from there. The fiber optics craze continues today with many companies using it to transmit data quickly both within their own walls and out in the world. Today, fiber optics is used for a wide range of purposes and benefits a variety of industries, including but not limited to industrial, broadcast, medical, communications and military industries.

According to The Guardian , new technological developments in fiber optics could make it up to times faster than it currently is. The advance is based on fibers detecting light that has been twisted in to a spiral.
