Intrinsic multichannel power control in cascaded power-equalizing erbium-doped fiber amplifiers [PDF]
We numerically investigate the performance of a cascade of four-channel power-equalizing reflective erbium-doped fiber amplifiers (EDFAs). The EDFAs reflect different channels at different points so that different channels interact with partly different ...
