POWER-OVER-FIBER FOR SENSORS IN SUBMARINE APPLICATIONS
Résumé
A power-over-fiber system consists in transmitting power supply over an optical fiber to a remote electrical equipment. Based on this technology, we present a 10 km long quasi-all-optical architecture dedicated to transmit energy to a seafloor instrument, and to exchange data in a full duplex configuration in real time. In this paper, we experimentally show the feasibility of such a system. We introduce our experimental prototype and we discuss about its key features. We describe both the optical link and the low consumption electronic system in charge of the data management and we present the system performances.
