Ra. Saunders et al., OBSERVATION OF PARAMETRIC NOISE AMPLIFICATION OWING TO MODULATION INSTABILITY IN ANOMALOUS-DISPERSION REGIME, Electronics Letters, 31(13), 1995, pp. 1088-1090
The transmission limitations for high bit-rate amplified systems owing
to a nonlinear effect known as modulation instability (MI) are presen
ted. Experimental results for a 20Gbit/s 560km amplified system show a
decrease in SNR of 8.5dB when operated 5nm into the anomalous dispers
ion regime, compared to 5nm into the normal dispersion regime.
