Working Principle and Types of Optical Fibers

Image
 Working Principle of Optical Fibers: Optical fibers work by guiding light along their length with very little loss. The core idea behind this is the phenomenon of total internal reflection . Total Internal Reflection (Main Concept) Total internal reflection occurs when light traveling inside a denser medium (like the fiber core) hits the boundary with a less dense medium (like the cladding) at a specific angle (called the critical angle). Instead of passing through, the light is completely reflected back into the core. For optical fibers: The core has a higher refractive index The cladding has a lower refractive index This difference ensures light keeps reflecting inside the core without escaping. As long as the light enters the fiber within a certain angle range, it will continue to reflect internally and move forward. How Light Travels Through Fiber  Light enters the fiber A light source (laser or LED) sends light pulses into the core at the correct angle. Co...
