Fiber Optic Cables

What holds the world together? More and more it's slender strands of glass thinner than a human hair.

These optical fibers carry light, chopped into pulses. The pulses carry information. They carry music, computer data, and TV shows. They carry millions of phone calls at the same time! How can light do this? How can glass? Find out.
