Communication system has been revolutionized with the advent of the optical fiber as it enables the high-speed data transmission up to thousands of kilometers across the globe with minimum distortion. Different methods are used to improve the performance of optical communication system but optical soliton is the most attractive phenomenon which use the dispersion and non-linear effect in such a way that they compensate each other and thus allows the pulse to travel without any distortion. This review was focused on the potential of soliton in optical communication system. The review started from the fundamentals of communication system. Then, it traced the physics of pulse propagation via optical fibre. The Maxwell's equation is used to derive the nonlinear Schrödinger equation (NLSE), and its dark and bright soliton solution is investigated. The higher-order NLSE is introduced for the future perspectives.
