The authors describe a 40Gbit/s soliton transmission experiment over 1000km using part of the Tokyo metropolitan optical loop network. The network consists of conventional dispersion-shifted fibres. A dispersion compensation technique was used to keep the average dispersion at a small constant value and this resulted in error-free 5ps soliton data transmission over 1000km. The power penalty at a bit error rate of 1 × 10-10 was between 1.7 and 2.4dB.
