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 1.3x10−15 at 1-s integration time, limited by long-term diurnal thermal effects. We developed and tested an improved setup with 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 Pa...
