## Abstract

Experimental Stokes vector spectroscopy characterizes polarization state noise in nonlinear fiber transmission. Noise bandwidths of a few MHz are observed from XPM-blurred receive SOPs using a polarization scrambling interferometer. This method can detect data pattern correlations among WDM channels that contribute to performance degradations in signalling.
