摘要：An optical communication amplification system may include a number ofamplification stages for an optical signal that includes a first optical wavelength band
signal portion and a second optical wavelength band signal portion. Each amplificationstage may separate the first optical wavelength band signal portion from the secondoptical wavelength band signal portion. The separated first optical wavelength bandsignal portion is amplified using one or more first optical wavelength band amplifiers andthe separated second optical wavelength band signal portion are amplified using one ormore second optical wavelength band amplifiers. The amplified first optical wavelengthband signal portion is filtered and a reflected portion of the first optical wavelengthband signal portion may be used to provide energy to the one or more second opticalwavelength band amplifiers to increase the power or gain of the separated secondoptical wavelength band signal portion.
