Abstract
In this paper we have presented the possibility of time and frequency distribution in two generations of dense wavelength division multiplexing (DWDM) networks: the older one, equipped with dispersion compensation fiber (DCF) modules, and the newest, without in-line chromatic dispersion compensation (dedicated for coherent signals). The experiments were performed in a 1500 km loop arranged in the PIONIER production network, with time and frequency signals regarded as so called “alien wavelength” network service. In the newest DWDM version we observed very good stability of delivered signals: Modified Allan Deviation approach 10−16 for averaging longer than 104 s (for 10 MHz frequency signal), and Time Deviation below 15 ps for averaging up to 105 s for 1 PPS time signal. These results show that the DWDM alien wavelength service can be used for high-demanding applications like cesium fountains comparisons. Results achieved for the former version of DWDM were about one magnitude worse for a long term comparison but it can still be useful for less demanding applications. We found that the main reason for relatively poor results observed in the older generation of DWDM is the impact of the dispersion compensation fibers used in this DWDM approach.
