本文研究了交叉相位调制效应（XPM）在多种情况下对开关键控（OOK）相干复用系统信噪比的影响.得到了单一信道下劣化因子的解析表达式和多信道情况下的计算模拟结果。本文认为，作为系统设计的原则，为了减小交叉相位调制引起的信噪比劣化.系统尽可能安排在小信号功率，小编码延迟时间方式下工作。
In this paper, the influence of cross-phase modulation effect (XPM) on signal-to-noise ratio of OOK coherent multiplexing system under various conditions is studied. The analytical expression of degradation factor under single channel and the calculation of multi-channel Simulation results. In this paper, as a principle of system design, in order to reduce the signal-to-noise ratio degradation caused by cross-phase modulation, the system is arranged to work as little signal power and small code delay time as possible.
