Abstract

This paper describes experiments on having organized power transmission over optical fibers (Powerover- Fiber, PWoF) for a seismoacoutic seafloor module, consisting of a three-component geophone and a hydrophone. The experimental setup includes a fiber-optic information and energy cable, a photovoltaic optical energy converter, and seismic sensors based on intermolecular electron transfer. It is shown that the efficiency of the conversion depends on the optical power incident on the converter and load connected to it, so that optimal conversion regimes of operation are found out. The results of field tests of the experimental setup in the White Sea are also presented.
