Optical Fiber Communication

Optical Fiber Communication is a modern method of transmitting information in the form of light pulses through transparent dielectric waveguides known as optical fibers. It has revolutionized the field of telecommunication due to its enormous bandwidth, low loss, and high transmission capacity. The fundamental principle behind optical fiber communication is Total Internal Reflection, which enables light to propagate along the fiber core with minimal attenuation. An optical fiber typically consists of a high refractive index core surrounded by a lower refractive index cladding, ensuring continuous reflection of light within the core.
