The present invention relates to a method and an apparatus for compensating for polarization mode dispersion in an optical transmission line (9, 9') with transmission characteristics that are dependent on polarization, in particular in optical fibres and cables with not only random but also with preferred double refraction. A compensation element(1, 1', 1"), preferably a double refracting fibre that contains polarization is incorporated ahead of or after the transmission line (9,9'), and the length of this is balanced by non-destructive means using an interference device (2, 2', 2"), in particular a pressure mechanism. Because of the interference, the polarization states P L and P S are mixed and this defines the length of the compensation fibre on which a delay time difference between the partial waves with polarizations P L and P S is built up or broken down, this compensating for the delay time difference T within the transmission line (9, 9')
