A two-channel long-haul soliton propagation system is demonstrated. Extensive variations of system parameters were numerically studied to provide the optimized system reported. In this system each soliton carries 80 Gb/s pseudo-random bit signal over 14,000 km. Key system parameters, such as the input peak power, the non linear coefficient, average dispersion and the number of sections of fiber in one amplifier length, are optimized, while the Q factor is monitored. As the Q factor falls below the threshold of 6.0 (corresponding to a BER of one error in a billion bits) the propagation distance is noted. For this optimized system a Q-factor threshold distance of 12700 km was obtained. This yields a bit-rate-distance (BL) product in excess of 2 ∙ 1015 b/s km.
