摘要：

Unlike single-channel systems, which favor saturated operation, multiwavelength erbium-doped fiber amplifier cascades offer substantial performance advantages when operated with minimal saturation at very strong inversion levels. This is due to ground-state absorption which, in partially inverted amplifiers, yields strong wavelength-dependent attenuation and thus large inter-channel power spread. In a strongly inverted six-amplifier chain, the inter-channel power spread per amplifier is suppressed by about an order of magnitude compared with the same system operated well into gain-compression.
