Description: Differential Group Delay measured and compensated by the module
What is facilityPhysInstValueDifferentialGroupDelay?
Reports the differential group delay (polarization-mode dispersion) measured and compensated by the module, expressed in picoseconds. DGD monitoring is essential in high-speed coherent systems to track chromatic impairments and verify that dispersion compensation is functioning properly. An example value might be 15.8 picoseconds indicating manageable polarization effects.
