A non-regenerative optical fibre transmission experiment over 904 km is reported. With a total net optical gain of 203 dB obtained from 12 cascaded Er-doped fibre amplifiers, 1.2 Gbit/s directly intensity modulated optical signals were transmitted without any optical bandpass filters and without an error floor.<<ETX>>
The first optical fibre transmission experiment using an Er-doped optical fibre amplifier as an optical repeater is reported. With an optical repeater gain of 20 dB, 1.2 Gbit/s intensity-modulated optical signals were transmitted along a 218 km dispersion-shifted optical fibre without any optical filters and without any degradation.<<ETX>>
