GRAVITY is the second generation Very Large Telescope Interferometerinstrument for precision narrow-angle astrometry and interferometric imaging inthe Near Infra-Red (NIR). It shall provide precision astrometry of order 10microarcseconds, and imaging capability at a few milliarcsecond resolution, andhence will revolutionise dynamical measurements of celestial objects. GRAVITYis currently in the last stages of its integration and tests in Garching atMPE, and will be delivered to the VLT Interferometer (VLTI) in 2015. We presenthere the instrument, with a particular focus on the components making use offibres: integrated optics beam combiners, polarisation rotators, fibredifferential delay lines, and the metrology.
