Delay Characteristics of Reservoir-Computing-Based Nonlinear Equalizer for Fiber-Optic Nonlinearity Mitigation
Tsuyoshi Yamada, Kai Ikuta, Yuta Ito, Moriya Nakamura · 2024
We investigated signals simply delayed by a reservoir computing (RC)-based nonlinear equalizer, which is designed to compensate for fiber-optic nonlinearity. The results show that the signal quality deteriorates with increasing the delay introduced by the RC, implying the equalizer's limitations and the necessity for adjustments in its application.
