Abstract :
Error-free soliton transmission at a bit rate of 5 Gbit/s over 250 km has been accomplished. The transform-limited soliton pulse source is a gain-switched DFB laser diode with a narrow-band spectral filter and Er amplifiers. A LiNbO3 light intensity modulator is used for pulse switching. A new pre-emphasis technique for sending solitons over a long distance is used, in which an Er3+-doped fibre amplifier is installed every 25 km as a lumped amplifier.
