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