Abstract

The authors consider long-haul, high capacity optically amplified IM/DD systems with non-return-to-zero (NRZ) data. They investigate the extent to which pre-chirping at the transmitter combined with optimized signal processing in the receiver can compensate for nonlinear waveform distortion caused by the combined effect of fibre chromatic dispersion and self-phase modulation (SPM) in systems with a small, constant value of normal dispersion. Research has shown that signal processing in the receiver can reduce the effect of waveform distortion due to fibre chromatic dispersion in short, single-span high-speed lightwave systems. They investigate the extent to which these techniques, together with pre-chirping at the transmitter, are effective in reducing waveform distortion in long-haul, high capacity optically amplified NRZ systems
