Abstract

- Resent research and development of optical clocks has increased the need and requirement of better performing time and frequency transfer over baselines longer than 100 km. This need have resulted in lot of activities in transfer methods using optical fiber. Some of them in dedicated fibers others in already existing fiber networks. This study has focused on one-way transmission over fiber optic WDM-network. The results show that it is possible to perform a one-way time and frequency transfer with two wavelengths and by evaluate these two against each other create a correction signal for compensation for influences along the transmission path. This experiment has shown proof of concept, but further work is needed. Future work includes development of a physical correction component in the end of the link that incorporates the steering signal from the difference between the two wavelengths.
