In the frame of 'GHANA project (phase II), IRCOM institute characterizes the 300-m long silica fibres which will link the Canada-France-Hawaii-Telescope and the Gemini telescope. In this paper, we report a method to compensate the differential chromatic dispersion between two 300-m long silica polarization-maintaining fibres. We experimentally show that the differential dispersion is not the same on each neutral axis of the fibre. Moreover, thanks to a channeled spectrum analysis, we are able to foresee the evolution of the contrast as a function of the wavelength and the spectral resolution over a given spectral band. Consequently, we are able to adjust the fibre lengths in order to maximize the contrast over J spectral window.
