Abstract
We describe the application of importance sampling to Monte-Carlo
simulations of polarization-mode dispersion (PMD) in optical fibers. The
method allows rare differential group delay (DGD) events to be simulated
much more efficiently than with standard Monte-Carlo methods and, thus,
it can be used to assess PMD-induced system outage probabilities at
realistic bit-error rates. We demonstrate the technique by accurately
calculating the tails of the DGD probability distribution with a
relatively small number of Monte-Carlo trials
