Reduction of Gordon-Haus timing jitter by periodicdispersion compensation in soliton transmission

A novel soliton transmission scheme to suppress the accumulation of the Gordon-Haus jitter using periodic dispersion compensation and inline optical filters has been proposed. With 90% dispersion compensation rate and optimum optical filters, a Q2 of 19 dB and a large power window of 2 dB were confirmed for a 20 Gbit/s, 9000 km transmission system by using a 1000 km-long recirculating loop.
