| 摘 要： | 导出了光相位共轭器（DPC）接于常规单模光纤链路中点的色散补偿波分复用（WDM）系统传输带宽的估算公式，并用数值仿真的结果验证了公式的正确性；采用不对称接入光相位共轭器提高传输带宽的方法，导出了光相位共轭器接入位置对传输带宽影响的估算公式，利用公式估算和数值仿真的结果表明，当光相位共轭器处于最佳接入位置时，色散补偿的波分复用系统的传输带可以提高近一倍。

| Abstract: | The estimation formula of transmission bandwidth of WDM system using optical phase conjugator (OPC) at the midpoint of standard fiber link for dispersion compensation is derived and verified by numerical simulation. The OPC is asymmetrically accessed in the fiber link to improve transmission bandwidth and the estimation formula of transmission bandwidth affected by OPC accessing position is derived. The results of both estimation and numerical simulation show that the transmission bandwidth of WDM system with OPC at the optimum position is increased nearly by one time as compared to that of WDM system with OPC at the midway. |
