Abstract: <P>PROBLEM TO BE SOLVED: To adjust the optical power of the optical signal of each wavelength which is wavelength-multiplexed and adjust the optical output power of each wavelength and deflection between wavelengths.  <P>SOLUTION: In an optical power adjusting unit 8, light is bifurcated using an optical star coupler 18. Lights of wavelengths λ1, λ2, and λ3 are respectively extracted from lights bifurcated by optical filters 20a, 20b, and 20c. Only light of the wavelength λ2 and light of the wavelength λ3 are independently amplified or attenuated using optical benefit adjusting units 17a and 17b. Then, lights of respective wavelengths are combined using the optical star coupler 19. The entirety of the combined light is amplified in an optical amplifier unit 9. The benefits of the optical amplifier unit 9 and the optical benefit adjusting units 17a and 17b are individually controlled.  <P>COPYRIGHT: (C)2007,JPO&INPIT
