摘要：

Unsaturated net gain of 51 dB is obtained for 1-551/nn signal light by using two-stage erbium-doped fibre amplifiers pumped by 1-48 /an laser diodes. This is achieved by using both an optical bandpass filter to suppress amplified spontaneous emission from the first stage amplifier and a bidirectional pumping scheme in the second amplifier to increase saturation output power. © 1990, The Institution of Electrical Engineers.
