ABSTRACT:
An optical fiber amplifier includes an input side wavelength combiner and an output side wavelength combiner arranged at an input side and an output side, respectively. An input optical signal is supplied from a transmission line to the input side wavelength combiner, while an output signal is supplied from the output side wavelength combiner to the transmission line. Further, an optical fiber is connected between the input side wavelength combiner and the output side wavelength combiner, an optical branch circuit is connected to the input side wavelength combiner and the output wavelength combiner and, a laser device is connected to the optical branch circuit and supplies an excited laser light beam to the optical branch circuit. The optical branch circuit divides the excited laser light beam into a first laser light beam and a second laser light beam with a predetermined dividing ratio and then supplies the first and second laser light beams to the input side wavelength combiner and the output side wavelength combiner, respectively.
