An investigation is made of the effects of initial or dynamically induced chirping on the linear propagation characteristics of pulses in optical fibers. It is shown that under certain conditions the chirping will give rise to a splitting of the initial pulse into two separating subpulses. The necessary conditions for pulse splitting to occur are established analytically and corroborated by numerical computations.
