Soliton: Gateway to future optical communication

Soliton in fiber optic is a good solution to achieve the benefits of optical fiber without many of its limitations like the use of more repeaters or amplifiers in case of long haul communication. This work considered three particular long haul systems (Three segments of SEA-ME-WE 4 sub marine cable Networks) and shown the difference between the signal response in case of fiber optics with Gaussian pulse and with Soliton pulse. The parameters considered for this purpose are- pulse broadening ratio, phase displacement, attenuation and number of amplifiers used. By simulation, both the pulses were transmitted through optical amplifiers and analyzed their performances to show that the performances with Soliton pulse are better than the performances with Gaussian pulse over the long haul fiber optics communication.
