  • Method of measuring the polarization mode dispersion of an optical waveguide device
    Patent number: 6020584
    Abstract: A method of measuring the polarization mode dispersion of a chromatic dispersion compensating optical waveguide device is provided. A force is applied multiple times to the spool flanges of a chromatic dispersion compensating optical waveguide device in order to obtain a plurality of polarization mode dispersion values which have a distribution characteristic of a Maxwellian distribution and provide a mean polarization mode dispersion value for the optical waveguide device.
