Abstract :
In this paper we present an ultra-stable fiber optical link which allows transferring radio frequency reference signal between two research laboratories. The link is composed of two 43 km twin optical fibers of the urban telecommunications network that connect the LPL to the LNE-SYRTE. The phase/frequency stability of the transferred signal is degraded by mechanical vibrations and temperature variations along the fiber. To correct these deleterious effects we develop a compensation system who acts directly on the fiber length with a variable optical delay line.
