A power-over-fiber system and its low consumption remote equipment for submarine applications

A power-over-fiber system using a single fiber optic of 10km devoted to transmit the energy to supply a remote equipment and also the up/down-stream data exchanged between a shore station and the equipment, is presented in this paper. Firstly, we present an overview of the developed quasi-all-optical architecture and its main communication protocol: the SPI. Then, we focus on its low consumption remote equipment and more precisely on a device called “the interface instrument” which is made of two main units. One realizes the optical toelectrical conversion to provide the power supply. The other one manages the optical data. Afterwards, experimental characterizations of the prototype are given and discussed.
