We numerically investigate the polarization-mode dispersion (PMD) tolerance of Stokes space based polarization-demultiplexing (SSPolDemux) algorithms in optical transmission supported by coherent detection and digital signal processing. The PMD tolerance is evaluated as function of the ratio differential group delay (DGD) over symbol period, allowing to identify a regime where SSPolDemux is performed practically without penalty (smaller than 1 dB), a regime where SSPolDemux is achievable but induces large penalties, and a third regime where SSPolDemux cannot be accomplished. Results show that coherent access/metro networks are
the most evident and potentiating application scenarios for SSPolDemux techniques.
