Time Transfer in Optical Network

Abstract

This paper describes experiments with two-way time transfer in an optical network. The method is based on newly developed adapters utilizing channels in a DWDM (Dense Wavelength-Division Multiplexing) network. We present results of several 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. The method is assessed and compared with One-in-view GPS satellite at geographical distance about 100 km.
