	For the XFEL accelerator, Thales, RI Research Instrument and LAL are working on the manufacturing, assembly and conditioning of fundamental power couplers. 670 couplers have to be manufactured according to strict specifications. The paper describes the full production activity from the program starting to the currentphase with main measurements for the coupler characteristic: copper and TiN coating characteristics. The status of the production is given with an output rate of 8 couplers per week. The status for more than 500 couplers manufactured and conditionned is presented.
