Abstract
We analyze the performance of multisection fiber polarization mode dispersion (PMD) emulators based on random fiber sectioning and ordered sectioning, with the inclusion of second-order PMD in individual sections. Numerical simulations show that this inclusion leads to (1) an asymmetry in the autocorrelation function (ACF) that increases with the magnitude of second-order PMD and whose form depends on the sign of the second-order term, and (2) a shift in the probability distribution functions of the differential group delay (DGD), and hence the mean DGD, with frequency that are undesirable. This behavior is found to be similar for both types of sectioning and has negligible effect on their corresponding background autocorrelation. This analysis leads to the requirement of suitable design parameters of fibers for which the second-order PMD in individual sections is minimized so that the desired ACF of the fabricated PMD emulator is symmetric and the mean DGD is the same at all frequencies.
