Abstract The very short optical soliton pulse transmission for the very high‐speed communication system is limited by the dispersion of the fiber. The problems due to the neighboring solitons, especially in the wavelength‐multiplex soliton transmission, is analyzed theoretically. As a numerical example, the soliton pulse of 2 ps pulsewidth with the preemphasis factor 1.4 can transmit 150 Gbit/s pulses for 12 km and by the wavelength‐division multiplex system, the 20 channel pulses with the wavelength spacing 1 nm and of 5 ps pulsewidth can transmit the pulses by 400 Gbit/s.
