Closed-Loop Polarization Mode Dispersion Mitigation for Fibre-Optic Time and Frequency Transfer
Thomas Fordell, Anders E. Wallin, Thomas Lindvall +1
A polarization switching pulse interleaver is shown to be effective in reducing timing noise due to polarization mode dispersion in time and frequency transfer based on mode-locked…
