Adaptive and DSP-Compatible Optical Multipath Interference Mitigation Scheme for 60Gbps PAM8-CRAN

We proposed an adaptive DSP-compatible time-varying multipath interference noise mitigation algorithm based on probability distribution over 15.5km SSMF at 56/60Gbps PAM4/8. The signal-to-interference ratio tolerance improvement of 3dB PAM8 shows its potentiality for high-order PAM.
