    • Embodiments of the present invention relate to a relay station and a method for adjusting output optical signals of the relay station. The relay station includes: a detection control unit, an output light stabilization unit, a reply stabilization unit, an adjustable gain amplification unit, and a pump light output unit. The method for adjusting output the optical signals of the relay station includes: adjusting a drive current which drives generation of pump light; adjusting a pilot tone modulation depth of an Alternating Current (AC) signal on which a replay signal is modulated; and finally, outputting a stable output optical signal through disturbed pump light. Adjusting the output optical signals and the pilot tone modulation depth of the AC signal on which the replay signal is modulated, the reply signals are stably output, thereby achieving the purpose of fixing the pilot tone modulation depth.
