In the context of the Phase-2 Upgrade of the CMS Experiment, the whole tracker will be replaced. The new CMS Outer Tracker will be equipped with two different types of silicon sensor modules called PS and 2S modules. During the LHC runtime, the modules and especially the silicon sensors will accumulate radiation damage, which lowers the signal measured by the module. In order to ensure the full functionality of the 2S modules during the entire operation time of CMS, modules in the advanced prototyping phase have been built. One of the prototypes features sensors that have been irradiated to fluences that are expected at the end of the CMS runtime. These unirradiated and irradiated prototypes have been tested at the DESY beam test facility. This talk summarizes the results gathered at the beam tests.
