Abstract
3 dB bandwidth of 52 nm (1556-1608 nm) for a silicate erbium-doped fibre amplifier (EDFA) and 50 nm (1554-1604 nm) for a fluoride (EDFA) have been obtained by a novel scheme with two-stage erbium-doped fibres and an intermediate equaliser. Low noise figures and high pump efficiencies of the EDFA´s have been confirmed
