Description: The arrival time difference between two polarization states at the output of the media (fiber).
What is ifPerfL0DifferentialGroupDelay?
The measured arrival-time difference between two polarization states of the optical signal at the receiver, in picoseconds; high values indicate polarization-mode dispersion in the fiber that can degrade high-speed coherent links.
