The Deep Underground Neutrino Experiment (DUNE) is a long-baseline neutrino experiment sending neutrinos from Fermilab to far detectors located 1.5 km underground at the Sanford Underground Research Facility (SURF) in South Dakota. One far detector module will use Vertical Drift (FD-VD) technology, drifting ionized electrons from a cathode plane suspended at mid-height in the cryostat. To increase photon detector coverage in the FD-VD, photon detectors (X-ARAPUCAs) will be installed along the cathode plane. Due to the high voltage (~300 kV) at the cathode, conventional copper cables cannot be used to power the photon detectors. Therefore, a novel application of Power-over-Fiber (PoF) technology will power the photon detectors via optical fibers in cryogenic and high-voltage environments. This talk presents the research and development of various PoF components under harsh conditions.
