摘要：

2223 km transmission distance is achieved with a 2-5 Gbit/s heterodyne detection system using erbium-doped-fibre in-line amplifiers and dispersion-shifted single-mode fibres. Twentyfive amplifiers placed at approximately 80 km intervals of fer a total gain of more than 440 dB. © 1990, The Institution of Electrical Engineers. All rights reserved.
