Performance comparison between two feedback signals for PMD compensation

  • 摘要: 为了研究光纤通信系统中存在高阶偏振模色散时,采用偏振度和电带宽作反馈信号,偏振模色散的补偿效果,采用数值模拟方法比较了两种常用的反馈控制信号对偏振模色散性能的影响,由模拟结果可知,从性能上讲,两种反馈信号都随1阶偏振模色散变化而具有线性变化,当系统中有高阶偏振模色散时,二者均不具有线性的变化,但偏振度的性能要优于电带宽信号。结果表明,这对偏振模色散补偿具有一定的指导意义。
    Abstract: In order to study the compensation effect of the polarization mode dispersion(PMD) when the degree of polarization and electrical power are employed as feedback signals in a fibre-optic communication system,the performance between two feedback signals are compared by means of numerical simulation.The simulation results show that when high order PMD is not considered,two signals are linearly changed with differential group delay(DGD).But when the high order PMD is considered,two signals are not linearly correlative with DGD.On the other hand,the performance of degree of polarization is better than that of electrical power.These results will be useful for adaptive PMD compensation.
