Abstract :
We present analytical expressions for the transfer function of periodically dispersion compensated optical links within intensity-modulated optical transmission systems. The accuracy of the proposed expressions is confirmed through the simulation based on the split-step Fourier method. With the transfer function, we thoroughly investigate the effects of precompensation and nonzero residual chromatic dispersion (CD) on the performance of periodically dispersion compensated optical links. We also introduce a fast and simple technique to determine the optimum link condition, such as the optimum amount of precompensation and residual CD, and show that there is an optimum monitoring frequency in the CD monitoring technique based on the sub-carrier tone.
