Relay station and method for adjusting output optical signals of relay station

The 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 comprises: 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 optical signals of the relay station comprises: adjusting the drive current which drives the pump light generation; adjusting the pilot tone modulation depth of the alternating current signal in which the reply signal is modulated; and ultimately outputting stable output optical signals through disturbed pump light. By respectively adjusting the output optical signals and the pilot tone modulation depth of the alternating current signal in which the reply signal is modulated, the relay station and the method for adjusting output optical signals of the relay station disclosed in the embodiments of the present invention enable stable output for reply signals which are modulated in the output optical signals, thus achieving the purpose of fixing adjusted peak depth.
