We have developed new expressions for power fading and average power fading owing to polarization mode dispersion (PMD) and chromatic dispersion in terms of the angle of precession of the output state of polarization about the PMD vector. Based on these expressions, a simple and novel pilot-tone-based technique for simultaneous monitoring of chromatic dispersion and PMD is proposed. Experimental results demonstrate the effectiveness of the proposed technique; these results agree well with the theoretical analysis.
我们已经根据输出偏振态绕偏振模色散(PMD)矢量的进动角度,推导出了由于偏振模色散(PMD)和色散导致的功率衰落和平均功率衰落的新表达式。基于这些表达式,提出了一种简单新颖的基于导频音的技术,用于同时监测色散和偏振模色散。实验结果证明了该技术的有效性;这些结果与理论分析非常吻合。
