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.
