Optical frequency transfer – a European network
Annotation in Czech
The project has the following objectives: 1. To connect two or more clocks belonging to NMIs in Europe with optical fibre links and enable multiple OC comparisons at a fractional instability level from 10-17 to 10-18 . 2. To assess and improve the accuracy and stability of remote optical frequency transfer by optical fibres, aiming for a fractional instability and uncertainty <10-19 (over one day). 3. To develop techniques that improve the reliability and scalability of frequency transfer over optical fibre, striving for continuous measurements (more than one day duration) and simultaneous operation of branched long-distance links. 4. To operate long-distance optical fibre links (measurement uncertainty <10-17 at one day) and to perform fast and accurate frequency comparisons (0.5-1 day duration, combined statistical Cs fountain clock uncertainty 2-3×10-16) between Europe's Cs fountain clocks. 5. To develop applications of fibre-based frequency comparison and dissemination techniques for very long-baseline (VLBI >300 km) geodesy experiments and for ground-space-ground frequency comparisons, especially to assess the performance of the MicroWave Link (MWL) and/or the EMPIR Page 8 of 56 15SIB05 OFTEN Annex 1 v1.0 European Laser Timing Link (ELT) technology in the Atomic Clock Ensemble in Space (ACES), by simultaneously comparing clocks over both fibre and space links. 6. To facilitate the take up of the technology and measurement infrastructure developed within the project by the measurement supply chain (accredited laboratories, instrumentation manufacturers) and end users (space, geodesy, telecommunications, etc.).

Project results evaluation
Following the condition that the candidate of financial contribution was evaluated and afterwards selected by international provider in accordance with the rules of the program the Ministry of Education, Youth ans Sports does not realize the evaluation of project results. The project is evaluated only after its approval by an international provider.
