Description: Differential Group Delay Low
What is dgdFacilityHistorical1dayLow?
Reports the minimum Differential Group Delay (DGD) measured in picoseconds over a 24-hour period, representing the lowest polarization-dependent signal distortion observed. In optical transmission, DGD is a critical metric indicating how different polarization states experience different propagation velocities through the fiber, affecting signal quality and dispersion compensation requirements. A typical value might be 2.5 ps, showing minimal polarization mode dispersion during the measurement window.
