Narrow band 1.02 Tbit/s (51/spl times/20 Gbit/s) soliton DWDM transmission over 1000 km of standard fiber with 100 km amplifier spans

1.02 Tbit/s (51-wavelength each at 20 Gbit/s) dense WDM (0.4 nm channel-spacing) soliton transmission over 1000 km of standard step-index fiber with 100 lan (21 dB loss) amplifier spans was successfully achieved for the first time.
