摘　　要：本文以平均近似法处理光纤链的损耗理论为前提 ,采用一组非零色散位移光纤链的参量 ,用分步傅里叶方法对 2 0 Gb/s,1 0 0 0 km的归零码光脉冲进行了数值模拟 .数值结果表明 ,在该光纤链上可实现双向准稳传输 。Using average approximation method,we deposed of the loss problem in the dispersion managed fiber link and obtained a set of parameters.Under this set of parameters,we analyzed the transmission with the pulse of 16 bit pseudo random RZ codes and the capacity of 20Gb/s by the means of numerical simulation.The result confirmed the stable bidirectional propagation can be realized even with the strong effect of the third order dispersion.
