G. Bellotti et al., 10 x 10 Gb/s cross-phase modulation suppressor for multispan transmissionsusing WDM narrow-band fiber Bragg gratings, IEEE PHOTON, 12(10), 2000, pp. 1403-1405
In this letter, we present a 10 x 10-Gb/s cross-phase modulation suppressor
based on series of WDM narrow-band fiber Bragg gratings. Its effectiveness
is demonstrated in a 5 x 100-km transmission over nonzero dispersion-shift
ed fiber. When the device is inserted within the repeaters of the link, the
observed bit-error-rate floor due to cross-phase modulation disappears, an
d a low penalty is obtained over a large range of residual dispersions, all
owing the transmission of a larger number of channels over longer distances
.
