In order to increase the dispersion-limited propagation distance at 10 Gb/s through nondispersion-shifted fiber, a chromatic dispersion tolerant signalling technique is used, based upon a reduced optical signal bandwidth. We have achieved a 210 km repeaterless transmission distance at 10 Gb/s over nondispersion-shifted fiber with a measured bit error ratio lower than 10/sup -12/. At this distance, a receiver penalty of 1.7 dB was obtained at 10/sup -10/ bit-error ratio, while an almost penalty-free transmission has been performed through 189 km. The technique relaxes the bandwidth requirements for the optoelectronic components at the transmitter level and involves a standard 10 Gb/s receiver at the output end of the transmission link.< >
