K. Sekine et al., 10 GBIT S 4-CHANNEL WDM TRANSMISSION EXPERIMENT OVER 500 KM WITH TECHNIQUE FOR SUPPRESSING 4-WAVE-MIXING/, Electronics Letters, 30(14), 1994, pp. 1150-1151
The authors have successfully demonstrated 10Gbit/s four-channel dense
ly spaced WDM transmission over 500km of dispersion-shifted optical fi
bre with a technique for suppressing FWM crosstalk. This result shows
the feasbility of future WDM transmission systems.
