Practical Design of Dispersion Managed Soliton System
Abstract
Here we present a model and simulation results for a dispersion-managed soliton system. In this system, both the dispersion map and launched power are optimized to maintain the soliton initial phase at each span length to reduce soliton interaction and soliton break-up. A practical design of the system using a dispersion compensation fiber is investigated for 10 ps-pulsewidth, 20 Gbit/s soliton signals transmitted over 18,000 km with 60 kin amplifier spacing. To demonstrate the suppression of soliton interaction by this technique, we kept the pulsewidth at 10 ps and increase the bit rate. We found that for a higher bit rate, a dispersion compensation fiber should be placed in each amplifier span to suppress soliton interaction. Simulation results suggest that by optimizing technical parameters, 40 Gbit/s soliton signals can be stably transmitted over 15,000 km and 50 Gbit/s soliton signals over the trans-oceanic distance of 9,000 km.
