Four-channel multiplexed 40 Gbit/s optical duobinary signals are successfully transmitted over a 100 km dispersion-shifted fibre for the first time. 40 Gbit/s based four-channel WDM transmission without individual channel dispersion compensation was achieved by virtue of the high dispersion tolerance of the optical duobinary signal
