Abstract
Embodiments of the invention include systems and methods for measuring or otherwise calculating polarization mode dispersion (PMD) of an optical fiber, or other device, by comparing the optical signal through the PMD element with the optical signal obtained directly from the transmitter, and calculating the PMD from the discrepancy between the two. Any distortions on the transmitter signal are effectively calibrated out, increasing measurement accuracy over conventional approaches.
