Abstract :
We present a 10/spl times/10-Gb/s cross-phase modulation suppressor based on series of WDM narrow-band fiber Bragg gratings. Its effectiveness is demonstrated in a 5/spl times/100-km transmission over nonzero dispersion-shifted fiber. When the device is inserted within the repeaters of the link, the observed bit-error-rate floor due to cross-phase modulation disappears, and a low penalty is obtained over a large range of residual dispersions, allowing the transmission of a larger number of channels over longer distances.
