- Från baksidan: "The basic concept underlying fiber optics was first explored in the 1840s when researchers used jets of water to guide light in laboratory demonstrations. The idea caught the public eye decades later when it was used to create stunning illuminated fountains at many of the great Victorian exibitions. The modern version of fiber optics - using flexible glass fibers to transmit light - was discovered independently five times throughout the first half of the century, and one of its first key applications was the endoscope, which for the first time allowed physicians to look inside the body without surgery. With the invention of the laser, researchers grew interested in optical communications. While Bell Labs and others tried to send laser beams through the athmosphere or hollow light pipes, a small group at Standard Telecommunication Laboratories looked at guiding light by transparent fibers. Led by Charles K. Kao, they proposed the idea of fiber-optic communications and demonstrated that, contrary to what many researchers thought, glass could be made clear enough to transmit light over great distances. Following these ideas, Corning Glass Works developed the first low-loss glass fibers in 1970."
