Investigations on optical timing jitter in dispersion managed higher order soliton system

Research Article


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.
