A Critical Analysis of Techniques to Eradicate Signal Distortions in Optical Fibers

Abstract

The latest methodology addresses the challenge of optical nonlinearity prevalent in fiber optics. It occurs when a high-intensity light pulse modifies the index of refraction of the fiber, thereby generating interactions between pulses transported at varying wavelengths. These interactions cause distortions that introduce errors, which are arduous to rectify, owing to the intricate mathematical complexities involved. Even though the nonlinearity in optical fibers is meager, it can significantly impact transmitted pulses when propagated across distances of several hundred kilometers or at speeds exceeding 10 gigabits per second.
