The Deep Underground Neutrino Experiment (DUNE) is a next-generation long baseline (1300 km) neutrino oscillation experiment. Neutrino beam measurements will be performed through near and far detectors. The far detector consists of four modules, installed 1,5 km deep underground, based on Liquid Argon Time Projection Chamber (LArTPC) technology to detect particles. In this talk I will discuss about the Signal and Power over fiber, being developed to operate at the Vertical Drift LArTPC.
