1. Would it not be better to ask GOOGLE?
2. I think late 70s early 80s, my friend asked me to invest in them in 81and i should have listened to him.
3. The light-guiding principle behind optical fibers was first demonstrated by Daniel Colladon and Jacques Babinet in Paris in the 1840s, with Irish inventor John Tyndall offering public displays using water-fountains ten years later.
