what is optical fibers?

A glass fiber may be a versatile, clear strand of terribly pure glass that acts as a lightweight pipe to transmit light between 2 ends of the fiber. Optical fibers have a core enclosed by a protective cover layer made from the material. The optical signals within the core area unit confined by establishing a ratio that's larger than the protective cover.

Optical fibers are employed as a medium for telecommunication and networking. Light in a very fiber optic cable travels through a core by perpetually bouncing from the protective covering, a principle termed total internal reflection. As the protective covering doesn't absorb any lightweight from the core, lightweight waves travel longer distances. Fibers with a large core diameter are also analyzed by geometrical optics. These fibers are called multi-mode fiber.
