Ra. Saunders et al., IMPACT OF CROSS-PHASE MODULATION FOR WDM SYSTEMS OVER POSITIVE AND NEGATIVE DISPERSION NZ-DSF AND METHODS FOR ITS SUPPRESSION, Electronics Letters, 32(24), 1996, pp. 2206-2207
The impact of cross-phase modulation (XPM) is measured on positive and
negative dispersion fibre. The exponential build-up of XPM over posit
ive dispersion fibre indicates amplification due to modulation instabi
lity. Methods for suppressing XPM crosstalk are also demonstrated.
