The fundamental working principle of an optical fiber is Total Internal Reflection (TIR). When a light ray enters the fiber, it strikes the boundary between the core and the cladding at an angle of. Optical Fiber: The optical fiber is a thin, flexible strand of glass or plastic designed to transmit light signals. It consists of a core, cladding, and protective outer layer. An optical fibre consists of an extremely thin, transparent, and flexible core surrounded by an optically rarer flexible cover called cladding. Many such fibres can be packed together in an outer cover.. As water can be sent from one place to another through a hollow pipe, a fibre can allow light to flow through it from one place to another. Hence, an optical fibre is often loosely called light pipe.
