1. Power sourcing equipment of a power-over-fiber system, comprising:
a first laser configured to oscillate with electric power to output a first feed light;
a second laser configured to oscillate with electric power to output a second feed light; and
a light input/output part configured to input the first feed light from by the first laser and the second feed light from the second laser to a single channel of an optical fiber,
wherein a light intensity distribution of the first feed light at an output end face of the channel differs from a light intensity distribution of the second feed light at the output end face of the channel, and
wherein the light input/output part inputs the first feed light and the second feed light simultaneously to the channel to reduce non-uniformity of a light intensity distribution at the output end face.
