Abstract
The optical fiber amplifier of the invention includes: a rare earth element doped optical fiber, and a pump light generator for optically pumping the rare earth element doped optical fiber. The optical fiber amplifier further includes a reflector for selectively reflecting an optical signal input from an input end of the rare earth element doped optical fiber to the input end, so as to give a gain to the optical signal.
