The Suppression Method On Timing Jitter Of High Rate Solitons Transmission System

In the WDM multi-channel soliton transmission system ,when the transmission rate up to10Gb/s,new situation which affect the stability of the transmission has come out with the high orderdispersion. This article discuss about the interaction of solitons fiber loss and amplificationtechnology for ultra-high speed optical communication systems, a few technology has been analysisand research in this paper such as the soliton stable transmission technology, frequency domaincombine the time domain of the composite control method and the various parameters in thedispersion management scheme. The inhibition of solitons in the mathematical model with thetransmission distance then use the mathematical method to analysis it which under soliton steep, thefrequency shift to the adverse effects of many higher-order effects. Design a 160 G high-speedmulti-channel soliton transmission system, and simulate and analysis soliton timing jitter values anda variety of different approaches to the role of soliton timing jitter values change.First of all, I reference to a lot of theoretical literature analysis, this paper we summarize therelevant theory analysis in reference materials of nonlinearities effects in the high speed andultra-long-haul DWDM communications system, then list a high-speed long-distance WDM systemtiming jitter various factors.Secondly, in this paper we introduction a multi-channel dispersion managed solitontransmission model and theoretical analysis on its merits and the impact on transmissionperformance, then derivate the evolution equation of a multi-channel dispersion-managed soliton ina variety of nonlinear parameters change as the transmission distance.Thirdly, after considering the conditions of the larger interaction between multi-channel WDMsoliton system interaction, according to the transmission evolution equation of soliton interactionand the timing jitter mechanism, since the higher-order effects of the steep and Raman scattering inthe time domain and frequency domain composited control methods of timing-jitter of suppressingthe soliton, and numerical simulation of the timing-jitter of 160G WDM soliton reach the distanceof 630 km, but using time-frequency methods to meet the control of soliton transmission up todistance of 5500 km.Finally, we analyze the impact of pre-chirped technology to multi-channel soliton pulse compression and broadening and the dispersion managed soliton mathematical model of WDMsystem analyze and design the system parameters to ensure that after a dispersion control, whenignore the dispersion management method, the stability of the transmission distance of soliton willreach 630 km, under controlled conditions of multi-channel dispersion-managed soliton system thelongest transmission distance up to 2900 km. Combined the basis of the dispersion managementmethod with frequency domain filter to control the timing jitter of the soliton, the stability of theresults of soliton transmission distance of 7200 km, we can see a variety of methods used incombination can be very good suppression of soliton timing jitter, to ensure the stable transmissionof soliton transmission system.
