S pecial Topic Computationally Efficient Nonlinearity Compensation for Coherent Fiber-Optic Systems Likai Zhu and Guifang Li
long-haul fiber transmission, the optical waveform and, consequently, the nonlinear behavior of the optical signal repeat at locations of identical accumulative dispersion. Hence, the DBP steps can be folded according to the accumulated dispersion. The effectiveness of dispersion-folded DBP for fiber links with large RDPS has been demonstrated numerically and experimentally. References
