The advantages of integrated optics for space interferometry are addressed: it can elegantly perform optical functions, such as coherent beam recombination, in a package that presents minimum weight and volume, and the components can be considered as 'black boxes' that require little or no alignment once they are implemented. FLUOR (Fiber Linked Unit for Optical Recombination), a ground demonstrator unit that enabled a pair of two existing 0.8 m telescopes to be transformed into an interferometer with a 5.5 m baseline is presented. The heart of FLUOR is a single mode fluoride glass triple fiber coupler: one X-coupler performs the coherent beam correlation, and two Y-couplers are used to monitor the starlight injection fluctuations in the fibers at the focus of each telescope. These signals are used in data reduction for calibration of the interferograms. In the last observing campaign several stars were observed with a precision of less than a few percents on the visibility measurements.
