    Abstract: A light amplifier includes a source of multiple light beams, each modulated with the same information, and a plurality of light amplifying optical fibers, each amplifying one of the light beams. The amplified light from each amplifying fiber is converted to electric form, and the electrical signals are summed to add the information and average the noise. In one embodiment, the bundle of fibers is twisted as it is wound about a cylinder, to average the compressive and tension forces on the fibers of the bundle. In another embodiment, a common cladding surrounds a bundle of fibers.
