A novel method to reproduce rare PMD events in transmission system simulation

摘要

In this paper, a novel method to reproduce the maximum DGD is proposed. In the model different PMD states are obtained by randomly varying the polarization coupling angle between sections. By confining the coupling angles' distribution to a shrinking range, the statistics of DGD will be distorted and the low probability events will be efficiently produced. The relationship between the mean DGD of changed DGD distribution and the angle range is given to make it convenient to choose a suitable angle range at a given maximum DGD and simulating sections.
