Optical solitons propagate stably through optical fibers, and overcome pulse broadening effect of the fiber dispersion. Since the pulse broadening effect increases with transmission speed, optical solitons should open the way to ultrahigh speed optical transmissions. This paper presents design strategies of ultrafast optical soliton transmissions, considering the propagation characteristics of optical solitons. We also describe a generation of transform-limited (TL) short pulses from laser diodes, which is one of the key technique for ultrafast optical soliton transmissions. Using this design strategy and the TL pulse generation technique, we demonstrate 80-Gb/s polarization-multiplexed optical soliton transmission over 80 km.
