Abstract
We show both numerically and experimentally that the nonlinear phase change due to XPM induces a bit-pattern-dependent change in the state-of-polarization that translates to uncertainty in the PSP. This effect severely limits the effectiveness of first-order PMD post-compensation and suggests the use of in-line compensation.
