Multipoint dissemination of RF frequency in fiber optic link with stabilized propagation delay

IEEE Trans Ultrason Ferroelectr Freq Control. 2013 Sep;60(9):1804-10. doi: 10.1109/TUFFC.2013.2766.

Abstract

In this paper, we present the concept of accessing the signal at some midpoint of a frequency dissemination system with stabilized propagation delay, which allows building the point-to-multipoint frequency dissemination network. In the first experiments with a 160 km-long fiber link composed of a field-deployed optical cable and fibers spooled in the lab, exposed to both diurnal and seasonal temperature variations, in the access node, we obtained the Allan deviation of a 10- MHz frequency signal of about 3 × 10(-17) and the time deviation not greater than 2 ps for 10(5) s averaging.
