Abstract
In optical media (e.g., an optical fiber) having first and second order polarization mode dispersion, the relationship between the polarization mode dispersion and the change in the measured averaged state of polarization of an optical signal in the media as a function of the signal's bandwidth can be predictable. Accordingly, first and second order polarization can be determined by measuring a series of the averaged state of polarization's for an optical signal with varying signal bandwidths.
