Introduction to Optical Fibers

Hardware Secrets teaches us about optical fibers basic anatomy and types. Here is a snippet:

"In 1952 physicist Narinder Singh Kapany, based on studies conducted by English physicist John Tyndall that the light could travel in curve inside a material (in Tyndall's experiment this material was water), could conclude his experiments that led to the invention of the optical fiber. Optical fiber is an excellent transmission medium used by systems that require a high bandwidth, like the telephony systems, video conference, local networks (LANs), etc." Read more here
