Objective: To present a detailed study of Solitons transmission system, including their types, applications, effects, and updated research work and research gaps. Findings: The 4 th , generation fiber optic communication system utilizes visual amplification to decrease the demand for repeaters and WDM to increase the information power. Similarly, 5 th the phase of Optical Fiber Communication is now expending the distances range which the wavelength division multiplexing system will control. The traditional wave length frame called the C ring covers the distance range 1.53 to 1.57 um and dry material has the low loss window promising extension of range to 1.30 to 1.65 um. Additional development includes the idea of visual solitons pulses that maintain their body by counteracting the results of distribution with nonlinear effects of this material by applying pulses of specific shape. Application: This will motivate the researchers to undertake research work in the field of Solitons communication to achieve improved design characteristics, reducing number of repeaters, cost and higher data rate transmissions.
