In a power-over-fiber system, the key limiting factor for transmission light power is the stimulated Brillouin scattering effect, which leads to a decrease in transmission light power at the end of the optical fiber. Therefore, we propose and experimentally demonstrate a broadband laser generated by a noise-modulated distributed-feedback laser diode to suppress the stimulated Brillouin scattering effect in the optical fiber. Experimental results show that the linewidth of the noise-modulated distributed-feedback laser diode broadens from 2.43 to 379.89 MHz when the noise modulation amplitude is increased from 0 to 400 mV. Due to the broadening of the laser linewidth, the stimulated Brillouin scattering threshold raises 7.19 dB, and the peak power of the Brillouin Stokes light is reduced by 40.90 dB. At the same time, the output electrical power at the end of the optical fiber increases 13.55 dB.
