Abstract :
We describe experiments with the AGH-designed fiber optic system for time and frequency dissemination, based on an active stabilization of the fiber delay. The measurements were performed at the Physikalisch-Technische Bundesanstalt, Braunschweig, over a field-deployed optical fiber loop going from PTB to the Magnesium clock laboratory in the Leibniz Universität Hannover and back (149 km, 45 dB attenuation).
