Paper Abstract

Polarization mode dispersion compensation for fiber communications systems of higher rate is of great importance. Key elements in polarization mode dispersion compensation are polarization controllers and differential group delay lines. Usual ways of compensation for PMD is to control both elements with the same feedback signals, which are processed with an algorithm for control of these elements. Algorithms should be designed for both the controller and delay line with an input signal and give out controlling signals for both elements alternatively. This may cause aimless action of DGD line or polarization state controlling. This paper gives a method of controlling these compensating elements, the polarization controller and the variable differential delay line, with different feedback signals, i.e., to control compensation elements for PMD Compensation separately. It uses Stocks parameters to control polarization controller and uses degree of polarization (DOP) to a variable delay line.
