Detailed explanation-1: -Fiber optic cables use strands of glass to propagate light. The light pulses transport communication signals between devices. At the center of the fiber optic strand is a small inner core that carries the propagated light.
Detailed explanation-2: -A fiber-optic cable contains anywhere from a few to hundreds of optical fibers within a plastic casing. Also known as optic cables or optical fiber cables, they transfer data signals in the form of light and travel hundreds of miles significantly faster than those used in traditional electrical cables.
Detailed explanation-3: -An optical fiber is a very thin strand of glass or plastic surrounded by several layers of protective coating. It is capable of transmitting light signals over long distances without significant attenuation (loss) or interference from outside sources.
Detailed explanation-4: -Fiber optic cable is made of many thin strands of coated glass fibers. Each measures about eight microns-that’s smaller than a strand of human hair.
