Abstract :
We aim at distributing the most precise frequency references provided by optical clocks, both from specialized labs to end users, and between specialized labs for comparing optical clocks. Transmitting an optical carrier over standard telecom fibre, we have transported frequency information over up to 900 km distance, with fidelity close to theoretical limits and reaching a precision of a few parts in 1018.
