“…In latter systems, timing jitter is also caused by pulse collisions. Thus, different pulse formats (Gaussian and Secant) and varied situations have been tried to avoid timing jitter induced with nonlinearity, amplifier noise, collision, acoustic and polarization by the researchers [16][17][18]. Generally, for ideal lossless and loss-managed solitons, GVD parameter is required to be kept constant along the fiber length.…”

The timing jitter in higher order dispersion managed soliton over 4,000 km link length has been investigated. The performance of the system under varied conditions of pulse shape, chirp factor, data rate amplifier spacing has been explored. The higher order soliton of gaussian shape in comparison to super-gaussian have shown reduction in timing jitter. Its results have been fitted in trend lines to form an empirical relationship with distance. The plots at varied chirp factor of gaussian and super gaussian shaped soliton for the system have been provided which show identical behaviour. However, fluctuations in timing jitter can be reduced by a proper chirp factor for the both. The timing jitter for gaussian shape soliton at data rates 20 and 10 Gbps has been plotted which indicates its early growth in the former data rate case. Further, varied amplifier spacing for the same 4,000 km link length in the system indicated that reasonably smaller amplifier spacing can reduce dispersion management induced timing jitter.

The theoretical derivation of optical time-domain fractional Fourier transformation is achieved and implemented. Based on the understanding of fractional Fourier transformation, we propose a new method for analyzing the influence of combined effects of dispersion and self-phase modulation on the propagation of optical pulses. And the simulation results show that when the dispersion is dominant in the transmission, a fractional Fourier transformation with a negative order number will help reduce the broadening of optical pulses induced by the dispersion. On the other hand, when the self-phase modulation is dominant, a positive order fractional Fourier transmission can help eliminate the pulse splitting effect.
