A method is disclosed of handling a Polarization Mode Dispersion (PMD) outage for optical signals on an optical fiber route between an optical transmitter and an optical receiver. The method comprises: determining that the PMD outage has occurred on the optical fiber route; in response to determining that the PMD outage has occurred, determining if the PMD outage is wavelength dependent; and in response to determining that the PMD outage is wavelength dependent, adding a wavelength converter to the optical fiber route, wherein the wavelength converter converts one of the optical signals from an optical wavelength affected by the PMD outage to a different optical wavelength.
