Abstract: This paper describes usage of all-optical network for time metrology application - Time and frequency transfer between two geographically distant sites. Although several approaches exist, there is no production implementation yet. Our method is based on newly developed adapters utilizing channels in a DWDM (Dense Wavelength-Division Multiplexing) network. We present results of tests performed in real production all-optical network including the time transfer between atomic clocks in Prague and Vienna over more than 500 km long optical path
