A state-of-polarization (SOP)-independent device (226, 326) and method for determining polyrization mode dispersion (PMD) in an optical communication system having an optical transmission line (224, 324), including a detector (244, 344), coupleable to the optical transmission line (224, 324), where the detector (244, 344) is capable of analyzing a pulse shape of an optical signal on the optical transmission line to determine PMD of the optical signal. A corrector (246, 346) may be coupled to the detector (244, 344), where the corrector (246, 346) is capable of compensating the optical signal for the determined PMD. A controller (242, 342) may be coupled to the detector (244, 344) and the corrector (246, 346). The pulse shape may comprise an eye diagram, which may contain a first peak and a second peak, due to PMD, where the PMD determined by the detector (244, 344) is a function of the distance between the detected first and second peaks which is indicative of a time delay between the detected first and second peaks. The device and method may also include a verifier (348) coupled to the corrector (246, 346), where the verifier (348) is capable of verifying that the corrector (246, 346) correctly compensated the optical signal for the PMD.
