Abstract: In order to over come the disadvantage of the traditional power supply method in the complex hazardous environments,a new type of power supply method that can replace the traditional intrinsically safe power supply system is proposed.The system uses the laser as energy carrier and uses optical fiber as transmission to achieve the long distance power supply. And a simulation of the optical fiber parallel transmission of energy and information is completed to verify the possibility of parallel optical fiber transmission of energy and information. And the power supply system is designed to achieve a long-distance optical power.
