摘要：

Early in 1998 the instrumentation Group at the Department of Extragalactic Studies (DEAC) of the Observatoire de Paris-Meudon (OPM) was confided the task to study and build a fibre Link system for the Canadian-France-Hawaii Telescope (CFHT) as an alternative for the original mirror train feeding the GECKO High Resolution Coude Spectrograph situated two floors below the telescope level. We report here on the advance of this project that is at present coming to completion after its successful preliminary commissioning in Hawaii in October 1999. We particularly emphasize the fibre link concept and its performances in terms of photometry and efficiency.
