Optical frequency links give the possibility to disseminate an ultra-stable frequency reference to many research laboratories for precise measurements as performed in frequency metrology and in applied and fundamental physics. We demonstrated first a simple branching network setup dropping an ultra-stable signal at different positions along an urban optical link of 92 km, that exhibits a relative frequency stability of 1.3×10-15 at 1 s integration time, limited by long-term diurnal thermal effects. We developed and tested an improved setupwith a compact and thermalized optical interferometer and a laser diode used to feed a secondary link, which fiber noise is compensated. These two setup open the way to multiple-users dissemination in Paris area and on the REFIMEVE+ network.Second we demonstrated optical frequency comparison using a two-way method. We tested the sensitivity of this comparison over a 100 km telecommunication fiber loop network using either unidirectional or bidirectional propagation, with an excellent frequency stability thanks to the very good rejection of the fiber noise.These results open the way to high-resolution frequency comparison of the best optical clocks over national or international fiber networks
