Our contribution presents the current state of operation and first experiments conducted on a recently established 232 km long Doppler-compensated fibre link between the Institute of Scientific Instruments in Brno (ISI), CZ and Federal Office of Metrology and Surveying in Vienna (BEV), AT, using communication infrastructure provided by CESNET. To demonstrate the link functionality, we measured phase noise power spectral density of a remote beat note of two independent lasers locked to high-finesse stable resonators. Using optical frequency combs at the both ends of the link, the long-term relative frequency deviation of local active hydrogen masers operating at ISI and BEV was estimated.
