The present invention relates to an apparatus and method for mitigating the effects of polarization mode dispersion (PMD) in high speed optical signal transmission systems. The apparatus comprises a concatenation of birefringent elements ( 11, 12, 16 ) of which at least two ( 11, 12 ) can be selectively controlled by means of a feedback device ( 15 ), and is capable of mitigating the effects of first- and second-order PMD even through the architecture used features a limited number of control connections ( 11 a , 12 a 9 and corresponding control signals. |
