    "abstract": "We present in this paper results on a new dissemination system of\nultra-stable reference signal at 100 MHz on a standard fibre network. The 100\nMHz signal is simply transferred by amplitude modulation of an optical carrier.\nTwo different approaches for compensating the noise introduced by the link have\nbeen implemented. The limits of the two systems are analyzed and several\nsolution suggested in order to improve the frequency stability and to further\nextend the distribution distance. Nevertheless, our system is a good tool for\nthe best cold atom fountains comparison between laboratories, up to 100 km,\nwith a relative frequency resolution of 10-14 at one second integration time\nand 10-17 for one day of measurement. The distribution system may be upgraded\nto fulfill the stringent distribution requirements for the future optical\nclocks.",
