Abstract
A polarization mode dispersion (PMD) compensator for compensation of PMD in polarization bit interleaved (PBI) optical signals is disclosed. The control uses spectral analysis of components of the electrical output, particularly analysis of a spectral component having a frequency corresponding to the bit frequency of the two bit streams which form the bit interleaved signal. Minimising this spectral component results in alignment of the signal in the system at 45 degrees to the two principal axes. An apparatus for measuring PMD based on spectral analysis is also disclosed.
