COMPENSATION OF MODAL DISPERSION OF POLARIZATION BY DETERMINISTIC JAMMING OF POLARIZATION

摘要

The invention relates to a method of calculating a series of control parameters to be applied to a polarization controller arranged so as to compensate for the modal dispersion of polarization affecting an optical signal passing through an optical link, the method comprising the calculation (A3) of a plurality of polarization states (SOPi) of which the respective representations on a Poincaré sphere are separated from one another by a distance (d) greater than a minimum distance (D) dependent on an acceptable threshold of bit error ratios and, for each state of polarization thus calculated, the association (A5) of at least one control parameter (Vai,Vbi) to be applied to the polarization controller with said calculated state of polarization. The invention relates to a method of compensating for the modal dispersion of polarization affecting an optical signal during its transmission through an optical fibre, comprising the successive application (B) of a series of control parameters, calculated (A) by means of the above method of calculation, to a polarization controller situated upstream of the optical fibre. The invention further relates to corresponding computer program products, a corresponding compensation device and an optical transmission system comprising such a compensation device.
