  • System and method for measuring and compensating for the polarization mode dispersion of an optical signal
    Patent number: 6980289
    Abstract: A system and method for measuring and compensating for the polarization mode dispersion of first and higher orders for a transmitted optical signal are described wherein the propagation time difference, caused from polarization mode dispersion, between orthogonally polarized signals of the transmitted optical signal can be determined very precisely, and can be compensated for, even above a delay of a bit duration of the data signal.

  • Circuit arrangement for dispersion compensation in optical transmission systems by means of an optical filter
    Patent number: 5867293
    Abstract: In a circuit arrangement for dispersion compensation in optical transmission systems by means of an optical filter, an optical transverse filter is provided as a negative dispersion filter, and which has a series of directional couplers which respectively follow one another at a spacing of .tau./2 and are operated as splitters. A series of directional couplers are provided which likewise follow one another at a spacing of .tau./2 and are operated as combiners, the second output of each directional coupler of the directional couplers operated as splitters leading in each case to the second input of the respectively corresponding directional coupler operated as a combiner.
