Abstract

We demonstrate a frequency comb-based time transfer technique on a 159\,km long installed fiber link. Timing information is superimposed onto the optical pulse train of an ITU-channel-filtered mode-locked laser using an intensity modulation scheme. The environmentally induced optical path length fluctuations are compensated using the round-trip phase noise cancellation technique. When the fiber link is stablized a time deviation of 300 fs and an accuracy of 80 ps is achieved.
