A 40 Gbit/s soliton transmission field experiment over 1,020 km was carried out as part of the Tokyo metropolitan loop network. The input and output waveforms (1,020 km) of a pseudorandom soliton pulse and corresponding spectra were analyzed. The bit error rate (BER) characteristics at 40 Gbit/s measured before and after a 1,020 km transmission were evaluated. Beyond 1,020 km, it is difficult to achieve error-free operation because of the rapid degradation in the transmitted waveform and the accumulation of nonsoliton components. An error-free transmission was achieved at 1,360 km extended transmission line at a received power of -29.5 dBm. The power penalty after transmission was 2.1 to 3.0 dB at a BER of 1×1010.
