Abstract
Determining the Outage Probability (OP) of fiber communication systems in the presence of Polarization Mode Dispersion (PMD) requires long simulation times. For a given average Differential Group Delay (DGD) ∆τ, sufficiently many fiber samples must be synthesized for propagation, so as to have fibers with first- and higher-order PMD effects large enough to degrade performance significantly. We choose here Sensitivity Penalty (SP), evaluated @BER = 10–10, as the performance indicator. Since such strong PMD fibers are rarely synthesized, propagation on most fibers yields SP values falling close to the modal SP value. Hence, one gets a poor definition in the tail of the SP distribution. Recently, importance sampling techniques have been proposed to increase the definition in the tail.1 Here, we take a different approach.
