【Abstract】 Nonlinear effect in high speed dispersion managed optical soliton communication system is researched. First, the impact of lumped amplification and distributed amplification to system nonlinear effect are compared. Then the rule of timing jitter and amplitude fluctuation changed with transmission distance in these two situations is analyzed numerically. As a result, the advantage of distributed amplification to restrain nonlinear effect is proved.更多还原
