Abstract: An optical fiber amplifier is disclosed including: an optical line through which an optical signal is transmitted; a rare-earth-doped fiber, doped with a predetermined rare earth ion, being set on the optical line; a pumping light beam source for generating a pumping light beam having a predetermined wavelength; a first multiplexer for coupling the pumping light beam to the optical line; a second multiplexer for dividing the pumping light beam outputted from the rare-earth-doped fiber; and pumping light beam looping means for looping the pumping light beam divided by the second multiplexer back to the rare-earth-doped fiber. The residual pumping light beam outputted from the rare-earth-doped pumping light beam is looped back by the feedback loop or reflection loop, to be reprovided to the rare-earth-doped fiber through the multiplexer. Accordingly, it is possible to reduce the length of the rare-earth-doped fiber remarkable, compared to the conventional case, and prevent the residual pumping light from being transmitted through the optical line.
