Modelling is used to assess the performance of an optical fibre link which has fibre grating dispersion compensators spaced at intervals along its length. A 10Gbit/s electroabsorption modulator with high positive chirp is shown to transmit in excess of 158km in normal dispersion fibre using two 2cm long compensators, incurring a dispersion penalty of only 1.0dB. Thus the transmission range is improved by a factor of 6.6 over the uncompensated case.
