PMD

(Polarization Mode Dispersion) The type of dispersion that occurs in singlemode fiber due to a lack of perfect symmetry in the fiber and from external pressures on the cable. Light travels over singlemode fiber in two polarization states. Over long distances, PMD causes each one to arrive at the receiving end at a different time. See dispersion.
