Abstract
The properties of the waveplate hinge model of polarization-mode dispersion (PMD) are
studied in detail, and its statistics are compared to those of the traditional hinge model
based on the assumption of an isotropic output after each hinge. In particular, the
probability density function of the differential group delay for each individual frequency
band is computed using a combination of importance sampling and the cross-entropy method. The
outage probability is then obtained combining these results with the outage map method,
allowing the fraction of bands with unacceptable outage probabilities to be quantified by the
noncompliant capacity ratio (NCR). The results show that the traditional hinge model
significantly overestimates the NCR compared to the waveplate hinge model.
