Abstract

In conclusion, we have resented a new type of soliton propagation. It requires both a dispersion compensation and an initial pre-chirp. Among its advantages, it is firstly compatible with the large chromatic dispersion of nondispersion shifted fibre (NDSF). Secondly, jitter and SNR performances are improved with respect to those of systems with constant chromatic dispersion due to the large value of the excess power coefficient k. Only soliton interaction is increased. Finally, in a 2500-km 20-Gbit/s transmission, it operates over a large power range: from <-1.5 dBm up to 11 dBm amplifier output power. These performances are much beyond those of single-channel NRZ systems
