A periodic pulse train launched within a linear dispersive optical fiber regenerates itself at distances that depend on the period of the pulse train. The effect of using a single longitudinal-mode laser source with a Gaussian power spectrum to modulate a periodic pulse train is considered, and the resulting expressions for regenerative periodic pulse trains are analyzed as functions of the source linewidth. It is shown that these pulse trains decay exponentially. Effects of operating such systems in the first- and second-order dispersion regimes are considered.<>
