When glass fibers of core/cladding style and design have been released while in the early 1950s, the presence of impurities limited their employment for the limited lengths sufficient for endoscopy. In 1966, electrical engineers Charles Kao and George Hockham, Doing the job in England, proposed using fibers for telecommunication, and within just two decades silica glass fibers ended up becoming generated with sufficient purity that infrared gentle signals could journey as a result of them for 100 km (sixty miles) or maybe more without needing to be boosted by repeaters.
