Abstract
A system and method for optimizing the performance, in a multichannel optical transmission system, of an optical signal regenerator, by compensating for input signal power fluctuation and for output signal gain change, and by mildly filtering individual wavelengths between gain block stages. A system and method to provide amplification and refinement of a bidirectional optical signal in a single amplification and refinement stage.
