Explain Fiber optic communication system. Answer: Like traditional metallic wire communication system, the fibre optic communication system also transmits various types of information from source to destination. The reason to use optical fiber in place of metallic wires in communication system is that they are cost effective, lightweight and they can carry greater data at a … [Read more...] about Fiber optic communication system

Fiber optics: Derivation for acceptance angle or numerical aperture
Derive an expression for Acceptance angle or Numerical aperture for fiber optics. Derive an expression for Fractional refractive index change or relative refractive index Answer: The light propagates through the fiber only when its angle of incidence at the launching end is less than or equal to a certain value. This maximum possible angle with the axis of the fibre up to … [Read more...] about Fiber optics: Derivation for acceptance angle or numerical aperture
