Abstract:
1. An optical network, comprising: a plurality of enhancement service sources, where each of the plurality of enhancement service sources provides source information; a plurality of light sources, coupled to the plurality of enhancement service sources, where each of the light sources is for modulating the source information from one of the plurality of enhancement service sources to form a modulated optical signal; a wave division multiplexer combiner, coupled to the plurality of light sources, for combining the modulated optical signals received from the plurality of light sources; at least two hybrid semiconductor optical amplifier-raman amplifiers, wherein a first of the at least two hybrid semiconductor optical amplifier-raman amplifiers amplifies the modulated optical signals in a first wavelength band, wherein a second of the at least two hybrid semiconductor optical amplifier-raman amplifiers amplifies the modulated optical signals in a second wavelength band, wherein the first wavelength band is different from the second wavelength band, wherein the at least two hybrid semiconductor optical amplifier-raman amplifiers are coupled to the wave division multiplexer combiner, wherein each of the at least two hybrid semiconductor optical amplifier-raman amplifiers is a two-stage amplifier that comprises a semiconductor optical amplifier stage and a raman amplifier stage; and an optical splitter, coupled to the at least two hybrid semiconductor optical amplifier-raman amplifiers, wherein the optical splitter comprises a plurality of outputs.
