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.
