A method and a device are described to compensate for polarization mode dispersion in an optical transmission link(9, 9') having polarization-dependent transmission characteristics, in particular in optical fibers and cables with not only statistical, but preferred birefringence. A compensation element (1, 1', 1''), whose length is adjusted non-destructively using an interference device (2, 2', 2''), in particular a pressure mechanism, is connected upstream or downstream from the transmission link (9, 9'). The polarization states PL and PS of the compensation element are mixed by the interference and thus the length of the compensation fiber is defined at which a propagation time difference between the partial waves of polarization states PL and PS is increased or decreased so that it compensates for the propagation time differenceτwithin the transmission link (9, 9').
