研究了40 Gb/s色散管理孤子传输系统中平均色散变化的容限。理论分析表明，色散容限由脉冲展宽和孤子相互作用决定，最大色散容限可以通过优化脉冲能量来实现。我们构建了一个40 Gb/s的循环环路传输系统，并表明，超过180 ps/nm的色散容限，这是远远大于线性不归零（NRZ）格式的系统，可以通过优化的脉冲能量在超过1000公里的传输距离实现。
We investigate the tolerance of the variation of average dispersion in a 40-Gb/s dispersion-managed soliton (DMS) transmission system. It is theoretically shown that dispersion tolerance is governed by pulse broadening and soliton interaction, and that the largest dispersion tolerance can be achieved by optimizing the pulse energy depending on the transmission distance. We construct a 40-Gb/s recirculating loop transmission system and show that the dispersion tolerance of over 180 ps/nm, which is much larger than that of a linear nonreturn-to-zero (NRZ) format system, can be realized by the optimization of the pulse energy at a transmission distance of more than 1000 km.
