We analyze in detail a simplified configuration of a compensation method based on a negative nonlinearity. It is shown that one can cascade the compensation of dispersive and self-phase modulation effects accumulated along a communication line without serious degradation in the quality of the transmitted signal. Anomalous and normal dispersion regimes are compared. Amplifier noise and higher-order...
The effects of the compensation ratio with dispersion post-compensation on nonlinear single channel and WDM systems with 10 Gb/s per channel are numerically investigated. When the transmission signal per channel is 10 Gb/s RZ pulse and the amplifier span is 50 km, proper undercompensation can enhance the performance of the nonlinear single channel system and the nonlinear WDM system. But the enhanced...
