We demonstrate that the use of fiber gratings to reverse periodically the pulse chirp in transmission links allows us to produce stable chirped optical solitons with fast-decaying tails. The interaction between neighboring pulses is reduced from that of the usual soliton system as a result of pulse chirping and strong confinement, making possible dense information packing. Such a pulse is an attractive candidate for use as an information carrier in optical transmission systems with ultralarge capacities of approximately 100 Gbits/s.
