Abstract :
This paper describes two-way time transfer over an optical network. The method is based on newly developed adapters utilizing channels in a DWDM (Dense Wavelength-Division Multiplexing) all-optical network. Results of several tests performed in real production network including the time transfer between atomic clocks in Prague and Vienna over more than 500 km long optical link are presented. In addition, the comparison of Common View GPS and optical time transfers is given.
