摘要：

EDFAs with high Al concentrations are optimised for wavelength division multiplexed (WDM) transmission systems. Gain excursion is succesfully suppressed to within 0.02dB/nm/stage for the six-stage common amplification of WDM signals ranging from 1545 to 1557nm. This result shows the possibility of multistage repeatered WDM transmission without gain equalisation.
