FiberopticsExcellent video on how fiber optics are made – “…”At the Speed of Light” is inspirational on any number of levels. It describes what Corning calls “the union of glass and light”. Developed in the 70’s by a trio of scientists — Drs. Keck, Maurer and Schultz — who went on to win the National Medal of Technology for their efforts, it is truly remarkable. They are making fibers thinner than a human hair. The single mode fiber is a mere 8 microns thick. One micron is one-millionth of a meter.” Link.
