When glass fibers of Main/cladding style were being launched in the early nineteen fifties, the existence of impurities restricted their work towards the shorter lengths adequate for endoscopy. In 1966, electrical engineers Charles Kao and George Hockham, Doing the job Rungrong in England, advised applying fibers for telecommunication, and inside of 20 years silica glass fibers had been being manufactured with ample purity that infrared light indicators could journey through them for 100 km (sixty miles) or maybe more without having to be boosted by repeaters.
