ABSTRACT:
An erbium doped fiber amplifier, which is equipped with an optical filter at its output port to eliminate noise caused by properties of the amplifier, automatically traces and filters transmitted light signal wavelengths using a wavelength control unit for adjusting the central wavelength of the optical filter to correspond to the wavelength of the transmitted light signal after determining the wavelength of the transmitted light signal.
