(For the KM3NeT collaboration) The KM3NeT consortium has completed a Technical Design Report (TDR) for a proposed multi-cubic-kilometer sized underwater neutrino telescope that will be deployed in the Mediterranean Sea. Highlights of the contents of the TDR will be presented in three poster presentations. In this first of three presentations we will focus on the details of the construction of the optical modules of the telescope and the proposed readout schemes. The basic unit of an underwater neutrino telescope is the Optical Module (OM), a pyrex glass sphere capable of withstanding the great pressure of the deep sea (3 to 4.5 km water depth) where the telescope will be deployed. The glass spheres house photomultipliers, either a single large PMT or many smaller ones, which register the Cherenkov light arising from the secondaries of neutrino interactions. The options for OMs under consideration will be described as well as the front-end electronics that will be located in the deep sea as well. The preferred proposed read-out schemes, a fully optical fiber based readout scheme where all the data gets transferred to shore, will be discussed as well as the overall data acquisition and control scheme of the detector.
