摘要

The PMD at a wide range of optical frequencies and statistics of all-order PMD, especially the first-, second- and third-order PMD, of a n-segment DGD units combination separated by PCs or PRs are fully analysed with Poincare sphere, Mueller matrix and Fourier transform methods. The results show that, to simulate all-order PMD in DWDM systems as truly as possible, the number of n should be as large as possible, the least value of 4 is preferred. The DGD units should be variable or unequal. Choosing PC or PR just affects the probability density function of PMD when n is not too much and the DGD values of the DGD units are unchangeable. At last, a simple, practical, and low cost all-order PMD emulator in DWDM systems is proposed.
