摘要：

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 lasers and standard single-mode (SM) fibers. In closed-loop time transfer over a 30-km dispersion-compensated fiber link with 300 fs of differential group delay, polarization interleaving reduced the delay variations to © 2025 Optica Publishing Group.
