Abstract

An optical fiber amplifier for optically amplifying a plurality of signals having different wavelengths includes a series of rare earth doped optical fibers and at least one pump light source generating pump light for exciting the series of rare earth doped optical fibers. A first signal among the plurality of signals propagates through a part of the series of rare earth doped optical fibers, and a second signal among the plurality of signals propagates through all of the series of rare earth doped optical fibers.
