Optical Timing and Synchronization for the Pacific Ocean Neutrino Experiment — •Lea Ginzkey, Christian Spannfellner, Michael Böhmer, and Elisa Resconi for the P-ONE collaboration — Technical University of Munich, Garching bei München, Germany

The Pacific Ocean Neutrino Experiment (P-ONE) aims to instrument more than one cubic kilometer of the Northeast Pacific Ocean off Vancouver Island (Canada) as a non-invasive next-generation neutrino telescope. P-ONE will measure high-energy astrophysical neutrinos and characterize the nature of astrophysical accelerators. A sub-ns timing synchronization within the photosensors in the detector volume is necessary to reconstruct the direction and energy of such highly energetic particles. Between the individual components of the P-ONE detector point-to-point fiber connections are used. A special implementation of ethernet allows to proliferate a central clock and synchronization signals to all modules in the system in real time, while offering a high bandwidth data connection by established protocols. This approach reduces the complexity of the system and cable design and optimizes the power consumption within the detector. First results of on- and offline delay measurements will be presented.
