The future KM3NeT neutrino telescope will consist of several thousand digital optical modules (DOMs), each of which will be equipped with 31 3-inch photo-multiplier tubes (PMTs). This design has various advantages over the use of one large PMT per optical module, e.g. concerning effective photocathode area per module, improved background suppression and directional reconstruction. Currently, the KM3NeT collaboration is testing a prototype DOM deployed on the instrumentation line of the ANTARES neutrino telescope. The DOM has been operational since mid-April 2013. First data are presented and compared to simulation results. The results are very encouraging and indicate that muon identification and a coarse direction estimation are possible event with a single DOM.
