Abstract
We propose a method for determining the spatial position of fast polarization
changes in a WDM system. In particular, we demonstrate that the PMD (polarization
mode dispersion) vector and Stokes parameters for each WDM (wavelength division
multiplexing) channel can be employed to find with an accuracy, shown to be
less than 15% in most simulated cases, the position of the sources of rapid
polarization fluctuations in a link with a mean DGD (differential group delay)
greater than 15 ps. The technique can also be applied to locate hinge positions
provided that only a single hinge is active at any given time.
