本文以数值求解非线性薛定谔方程主要分析手段，对全通光均衡器色散补偿传输系统的性能进行了研究。对单波长传输系统的数值模拟结果表明：系统工作波长和光均衡器谐振波长的稳定性对补偿效果影响显著。提出了适合波分复用系统中进行色散补偿的光均衡器参量，并进行了数值模拟，结果表明：对于信10Gb／s、常规单模光纤组成的波分复用系统采用单个光均衡器可同时对偿，传输距离可达100km左右.

The performance of dispersion compensated transmiss ion system with all-pass equalizer is analyed.It′s proved that stability of si gnaling wavelength and equalizer′s resonance wavelength are critical to the co mpensation effect.Then the principle of the all pass equalizer in WDM system is introduced.The algorithm for equalizer′s parameters is presented.Some useful r esults are obtained.
