Abstract: PURPOSE: An optical repeater and optical signal amplification method are provided to reduce influence on noise generated from amplification operation for specific optical signals by controlling the amplification operation. CONSTITUTION: An UL(UpLink) optical amplification apparatus(144) amplifies an input UL optical signal from an input optical signal. When an UL stream is detected from the input UL optical signal, a control unit(147) amplifies the input UL optical signal by controlling the UL optical amplifier. When the UL stream is not detected from the input UL optical signal, a control circuit stops the amplification operation for the input UL optical signal by controlling the UL optical amplifier.
