Wavelength Division Multiplexing for the Pacific Ocean Neutrino Experiment — •Lea Ginzkey for the P-ONE collaboration — Technical University of Munich

The Pacific Ocean Neutrino Experiment (P-ONE) aims to detect high-energy astrophysical neutrinos by instrumenting more than one cubic kilometer of deep ocean water in the Northeast Pacific, off the coast of Vancouver Island (Canada). With the first detector line nearing deployment, planning for the next stages of P-ONE is already underway.

To decrease both cable production complexity and overall cost, we aim to reduce the number of fibers per module while maintaining DAQ redundancy. Wavelength Division Multiplexing (WDM) enables the simultaneous transmission of multiple independent optical channels through a single fiber, offering a promising path towards more efficient deep-sea readout architectures.

The current status of WDM tests for P-ONE will be presented, providing an outlook on how WDM could support the next generation of large-volume oceanic neutrino detectors.
