Abstract
An arrangement and method for producing a predeterminable polarization mode dispersion by means of double refracting elements provides for the production of a second-order polarization mode dispersion. An element is envisaged which twists the polarization principal axes by an appropriate angle at the output of an arrangement for producing first-order PMD, and the light signal exiting this element is fed into an arrangement which is also an arrangement for producing first-order PMD to produce an output signal having both first- and second-order PMD.
