Abstract
A method and system for estimating a fraction of an optical transmission system's transmission window that is compliant with the system's polarization mode dispersion (PMD) outage specifications, the optical transmission system including Noptical fiber segments. The method comprises the steps of: propagating a plurality of optical signals through the Noptical fiber segments; monitoring the differential group delay (DGD) for each optical signal over time; computing a time average and variance of the monitored DGD for each optical signal; computing statistics of the time averages and variances of the monitored DGD for each optical signal; determining the number of effective PMD sections and effective hinges in the system from the statistics; and determining the size of a PMD capacity compliant fraction for a specified outage probability.
