Abstract

We design a polarization mode dispersion (PMD) emulator with a fixed root-mean-square differential group delay (RMS-DGD) but varying second-order PMD (SOPMD) using only a combination of polarization maintaining fibres and a polarization controller. Besides controlling the mean PMD values of the emulator, simultaneous adjustments in the maximum and minimum values of PMD statistics can be performed. Therefore this novel design will achieve more realistic statistical distribution by exhibiting irregular fluctuations that occur around the RMS-DGD due to SOPMD.
