The effect of time and frequency control of dispersion-managed soliton systems by synchronous amplitude modulators and fix-frequency filters is evaluated using variational method. The analytical formulas are obtained and can be used to calculate timing jitter with different soliton control parameters. Thus one can optimize the design of synchronous amplitude modulator and fix-frequency filter. The results also show that fix-frequency filter can suppress timing jitter contributed by Raman effect.
