What is Fiber Optic Ethernet?
First commercially deployed in 1977, optical cable is the primary source of long-distance, high-bandwidth communications between telephone companies, multi-site organizations and various other long-range communications applications. An optical fiber is a flexible, transparent strand of very pure glass that acts as a light pipe to transmit light between two ends of the fiber. Optical fibers have a core surrounded by a protective layer made of dielectric material. Light in a fiber optic cable travels through a core by constantly bouncing from the protective layer, a principle termed total internal reflection. As the protective layer does not absorb any light from the core, light waves travel longer distances.
