40Gbit/s soliton transmission over 400km (57km amplifier spacing) of instal
led lines without in-line control has been achieved. The maximum transmissi
on penalties for parallel polarised and polarisation division multiplexed s
oliton transmission were similar to 4 and 1 dB, respectively. The transmiss
ion distance is the longest ever reported for a field trial with a single w
avelength bit rate > 20 Gbit/s for any optical transmission format. The pol
arisation mode dispersion was numerically found to completely dominate the
system performance.
