O. Leclerc et al., 2X20GBIT S, 3500 KM REGENERATED WDM SOLITON TRANSMISSION WITH ALL-OPTICAL KERR FIBER MODULATION/, Electronics Letters, 34(2), 1998, pp. 199-201
Regeneration through Kerr fibre phase modulation is proposed and appli
ed for the first time to wavelength-multiplexed soliton signals. Perio
dic regeneration by Ken fibre modulators without the use of guiding fi
lters and dispersion management is shown to increase the error-free di
stance in 2 x 20Gbit/s WDM soliton transmission up to 3500 km.
