Abstract

The 'OHANA aims at demonstrating the potential of single-mode fibers to make large telescope arrays with kilometric baselines. In this respect, propagation in single-mode fibers is critical. Transmission needs to be excellent, differential dispersion needs to be cancelled and polarizations have to be matched. 2x300 m of fibers have been produced for the first 'OHANA baselines. Their transmission has proved to be excellent and their differential dispersion has been almost perfectly cancelled thus bringing the fundamental components of the experiment to reality. The work reported in this paper is part of a global work on fibers in the 'OHANA project. Vergnole et al. describe the results achieved on silica fibers in the astronomical J and H bands.
