High-resolution time and frequency transfer between remote laboratories are of major interest for many fundamentals applications, such as tests of general relativity or temporal variation of fundamental constants performed by comparing clocks signals. We report on the progress of a metrological fiber network on the French territory, with extensions to Europe, which aims to provide an ultra-stable frequency signal to around 20 laboratories. This network is based on the dissemination of an ultra-stable signal using optical links through the academic fiber internet network. As a first step, we have demonstrated robust links of up to 1480 km with stability at 104s and accuracy below 10−19.
