| 摘 要： | 研究了应用级联相敏光放欠器(PSA)的非零色散位移光纤(NZDSF)光传输系统。通过计算机仿真得到了高速信号眼图劣化度随光纤色散变化的曲线，以及系统码间干扰(ISI)限制无中继距离在不同色散条件下随放欠器间距变化的曲线。通过分析可知，PSA对光纤的正色散和负色散都有一定的补偿效果。但是，由于非线性自相位调制效应的影响，在其它参数相同条件下，正色散时的ISI限制距离比负色散时要长得多。

| Abstract: | This paper focuses on the non-zero dispersion shift fiber optical transmission system which employs cascadecl phase-sensitive amplifiers. By computer simulation, we got that eye-penalty of highspeed signal increases with the accretion of dispersion and the transmission distance limited by intersymabol interference of signals changes with the spacing of amplifiers on different dispersion value. From our analysis, we know that PSA can compensate fiber dispersion, either positive dispersion or negative dispersion. But for the infuence of self-phase-modulation, the ISI limited distance of positive dispersion is much longer than that of negative dispersion. |
