A distributed gain optical fiber amplifier makes use of a single or a plurality of counter propagating pumping optical beams, and a plurality of short lengths of doped fibers that are distributed along an optical network. Pumping optical beams is introduced into the fiber by coupling single or a plurality of pumping laser sources that can be operating at the same wavelength using a wavelength division multiplexer coupler. As the pumping energy propagates through the short lengths of the doped fibers some portion of the pump energy is transferred into the signal, which is propagating along the same fiber, causing it to be amplified.
