J. Kani et al., Bidirectional transmission to suppress interwavelength-band nonlinear interactions in ultrawide-band WDM transmission systems, IEEE PHOTON, 11(3), 1999, pp. 376-378
Interwavelength-band nonlinear interactions are investigated as possible ca
uses of performance degradation in ultrawide band wavelength-division-multi
plexed transmission. These interactions can severely limit the performance
of transmission over dispersion-shifted fibers (DSF's) and nonzero DSF's, B
idirectional transmission is found to be effective in suppressing interwave
length-band nonlinear interactions.
