Optical distribution networks : signal-to-noise ratio optimization and distributed erbium-doped fiber amplifiers
… remotely-pumped erbium-doped fiber amplifiers in optical distribution networks are analyzed. We investigate the optimal allocation of gain and loss among the stages of a lumped amplifier chain, using the concepts of a Nash solution and Pareto optimality. The propagation of optical channels along …
