An optical fiber power-delivery system has been developed. An analysis of the spectral response of every component in the system has been carried out. Experimental measurements of the system are presented. We obtained 205 mW of power (5.4 V, 38.3 mA), yielding 27.4% efficiency. As an application, a sensor module is optically powered. This is an electrically isolated system, inasmuch as it also sends the measured data through a fiber. Several other applications are envisaged in the fields of aerospace, avionics, and domotics.
