  • Abstract
    The optimum gain-equalised configuration for the erbium-doped fibre amplifier (EDFA) using a samarium-doped fibre (SDF) is investigated. The dual-pumping scheme with inter-stage SDF and midway isolator was found to be the optimum scheme for obtaining flattened high spectral gain with variation of ⩽±0.7 dB and with a low noise figure of ⩽5.6 dB within the 1530-1560 nm range. This amplifier is suitable for multiwavelength transmission systems containing EDFA cascades
