A method for amplifying a burst optical signal, a burst optical amplifier and system, and a communications system are provided according to embodiments of the present invention. The method for amplifying a burst optical signal includes: combining, by a combiner, auxiliary light and signal light into mixed light and outputting the mixed light, where the auxiliary light is non-burst light, the signal light is burst light, and power of the auxiliary light is set to be independent from power of the signal light; generating pump light; and combining, by an optical wavelength division multiplexer, the pump light with the mixed light and inputting the combined light into a gain medium, so as to obtain amplified mixed light. In the above method for amplifying a burst optical signal, a burst optical amplifier, and a communications system, because the auxiliary light always exists, the burst optical amplifier always operates in a state of amplifying light. The pump light exists in the gain medium, and the pump light may directly amplify the entered signal light, thereby reducing the delay time of enabling the burst optical amplifier, improving the transient response speed of the burst optical amplifier, and preventing the generation of a surge phenomenon, so as to prevent the generation of signal distortion.
