This paper describes the stable soliton propagation in a practical transmission line and the suppression of the Gordon-Haus effect to achieve long-distance ultra-fast optical soliton transmission. Since the distributed loss/gain and fluctuated dispersion in actual transmission fibers influences the stable soliton propagation, we numerically estimate the condition for stable propagation. We also discuss the limit of transmission distance using optical filters to reduce the Gordon-Haus effect. A 10Gb/s recirculating loop transmission over 6700km is demonstrated to confirm the suppression of the Gordon-Haus effect with optical bandpass filters and stable soliton propagation utilizing the recirculating loop with distributed loss/gain and fluctuated dispersion.
