Lilin Yi, lei xue, Rui Lin, luyao Huang, Jiajia Chen
2021 Optics Express  
In this paper, for the first time, NN-based equalizer is proposed to mitigate the SOA pattern effect for 50G PON with intensity modulation and direct detection.  ...  However, the annoying nonlinear pattern effect degrades system performance when the SOA is needed as a pre-amplifier in PONs.  ...  as 29 dB for the 50G PON system.  ...
