A new theoretical analysis of the interferometric polarization-mode dispersion (PMD) measurement predicts, in the limit of large PMD, a new relationship to the highly mode-coupled principal states model. This theory is confirmed by computer simulation of the ratio of the mean differential group delay (DGD) to the interferometric PMD. Jones matrix eigenanalysis and wavelength scanning with extrema counting are shown to measure the mean DGD independently of the optical source spectrum, whereas interferometrically measured PMD is shown to depend on the optical source spectrum as well as on the characteristics of the fiber to be measured.
对干涉式偏振模色散（PMD）测量的一种新的理论分析预测，在大PMD极限情况下，与高度模式耦合主态模型存在一种新关系。通过对平均差分群时延（DGD）与干涉式PMD之比的计算机模拟证实了该理论。琼斯矩阵特征值分析和带极值计数的波长扫描被证明可独立于光源光谱测量平均DGD，而干涉测量的PMD则被证明既取决于光源光谱，也取决于待测光纤的特性。
