Investigations in high-speed optical systems, based on a line data rate of 160 Gb/s, identified the nonlinear single-channel effects self-phase modulation, intrachannel four-wave mixing, and intrachannel cross-phase modulation as the main limiting factors beside polarization-mode dispersion, chromatic dispersion, and dispersion slope. In this letter, we investigate the impact of nonlinear single-channel effects on the transmission performance of 160-Gb/s systems. We determine an analytical engineering rule for the estimation of system performance and system reach for 160-Gb/s systems, considering various fiber types and amplifier concepts.
