Abstract :
In this paper, we report the performance-analysis results of our proposed high-speed and low-cost feedback-control method of a tunable-dispersion compensator (TDC) for adaptive dispersion compensation in all-optical dynamic-routing networks. In this method, we monitor the received waveform in the time domain and control a TDC repeatedly to reshape the waveform by means of the steepest descent method. Transmission experiments and simulations show that the proposed method can compensate for the dispersion quickly over a wide dispersion range. The compensation range is from -6000 to 6000 ps/nm in 10-Gb/s transmission. The compensation time is 1-2 s for dispersions within 1000 ps/nm. This method is applicable to the adaptive dispersion compensation in all-optical dynamic-routing networks
