摘要:
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 (11a, 12a9 and corresponding control signals.
