Performance analysis of Q-factor on wavelengths and bit rates using optical solitons with dispersion management

Abstract

In this paper, the dispersion management using soliton pulses in optical communication system is studied. The performance of the system with and without soliton parameters in terms of Q-factor, BER, and eye diagram is also studied. The proposed system with soliton parameters provides an improvement in Q-factor value by 82.1118 dB compared to that without soliton parameters at bit rate of 20 Gbps at a wavelength of 1550 nm with minimum BER of 0. Thus, soliton pulse can be transmitted dispersion free over optical fiber due to the exact compensation between nonlinearity and group velocity dispersion. The impact of wavelengths and bit rates for the soliton system on Q-factor, BER, and eye height is also investigated. The analysis of the simulation results provides that the values of Q-factor and eye height are inversely proportional to wavelength and proportional to bit rates in the proposed system with soliton parameters. Besides, it is proposed that the soliton pulse is best suited for long-range communication system with dispersion management.
