AB  - This article reports on the use of a Field Programmable Gate Array (FPGA) 
      platform for local ultra-stable optical frequency distribution through a 90 
      m-long fiber network. This platform is used to implement a fully digital 
      treatment of the Doppler-cancellation scheme required by fiber links to be able 
      to distribute ultra-stable frequencies. We present a novel protocol that uses 
      aliased images of a digital synthesizer output to directly generate signals above 
      the Nyquist frequency. This approach significantly simplifies the setup, making 
      it easy to duplicate within a local fiber network. We demonstrate performances 
      enabling the distribution of an optical signal with an instability below 10(-17) 
      at 1 s at the receiver end. We also use the board to implement an original 
      characterization method. It leads to an efficient characterization of the 
      disturbance rejection of the system that can be realized without accessing the 
      remote output of the fiber link.
