[en] The ANTARES collaboration is building a deep underwater neutrino telescope to be immersed in the Mediterranean Sea 40 km off the French coast. This detector will be able to detect the Cherenkov light emitted by muons produced in neutrino interactions using a three-dimensional matrix of optical sensors. The telescope will be made of nearly 1000 of these elementary units distributed over a wide area of about 0.1 km² at an average depth of 2400 m. In order to reach a sub-nanosecond resolution on light pulse detection, signals from all OMs are analyzed and digitized locally before being sent to shore through a 50 km electro-optical cable. Front-end electronics, time alignment (clock distribution), triggering and data acquisition for such a large and remote detector represent a real challenge and required considerable R and D studies. The technical solutions adopted by the collaboration will be described and their performances discussed
