Abstract
A high power pumping apparatus for optical fiber amplification includes: a pumping portion for generating pumping light of a predetermined wavelength band, the wavelength of which is determined by the wavelength of the pumping light fed back from a subsegment portion; a wavelength division multiplexer for multiplexing the pumping light generated by the pumping portion, for dividing the signal light incident from a subsegment portion according to wavelengths, and for outputting the signal light to the pumping portion; and a broad-band reflecting portion for reflecting some of the output light multiplexed by the wavelength division multiplexer, for outputting the reflected light to the wavelength division multiplexer, and for outputting the remaining light as pumping light for light amplification. In the high power pumping apparatus according to the present invention, the same pumping diodes can be used without a wavelength selecting diode. The high power pumping is useful for optical fiber amplification for a cable TV and for remote pumping since the pumping is performed therein in a wide spectrum range.
