Popis: | The contribution reports on the current state of the fibre link for phase-coherent transfer of optical frequency between ISI CAS (Brno, CZ) and CESNET (Prague, CZ). The 306 km long link is operated on an internet communication fibre in a dedicated 1540–1546 nm DWDM window. The narrow linewidth laser Kohereas ADJUSTIK working at 1540.5 nm locked to the nearest tooth of the stabilized optical frequency comb referenced by the H-Maser serves as the laser standard at the transmitting side. |
