In the frame of the Optical Hawaiian Array for Nanoradian Astronomy (‘OHANA) project, 300-m long silica fibers are necessary to coherently link the Canada France Hawaii and Gemini telescopes. In this paper, we report measurements of the differential chromatic dispersion between two 300-m long silica polarization maintaining fibers for the astronomical J band (1.10 1.40 μm) as a function of the temperature variation on one fiber arm of the interferometer. We demonstrate that the second order coefficient of chromatic dispersion increases linearly with the temperature. Consequently, we propose two methods to compensate this additional and variable differential chromatic dispersion: the first one using a dispersive optical fiber delay line and the second one using a set of CaF2 bulk plates.
