Abstract
In the paper the authors present their experiments oriented on transferring time and frequency signals over modern telecommunication networks carrying 40/100 Gbps signals using coherent techniques. The experiments were performed in 1500 km-long loop arranged by PSNC in the PIONIER production network. We observed good stability of delivered signals: Modified Allan Deviation of 10 −15 at 10 3 s averaging (for 10 MHz frequency signal), and Time Deviation below 10 ps for averaging up to 10 5 s for 1 PPS time signal.
