Differential Group Delay is related to Polarization Mode Dispersion (PMD). PMD monitors the performance of dual polarization modulation signals operating on a single wavelength. PMD introduces frequency dependent pulse spreading, statistically applied over the length of the fiber connection. PMD is caused by slight imperfections or asymmetries in the fiber core and causes light in one polarization axis to travel at a different rate than light in the orthogonal axis.
