Experimental investigation of dispersion management for an 8/spl times/10 Gbit/s WDM transmission over non-zero dispersion shifted fiber

We experimentally demonstrate that an 8/spl times/10 Gb/s WDM transmission with 200-GHz channel spacing over nonzero dispersion-shifted fiber requires dispersion compensation when using channel powers compatible with field requirements. The management of this compensation is then investigated and optimized.
