High-Capacity and Rain-Resilient Free-Space Optics Link Enabled by Time-Adaptive Probabilistic Shaping

Using time-adaptive probabilistic shaped 64QAM driven by a simple SNR prediction algorithm, we demonstrate \(>\)450 Gbps transmission over a 55-m free-space optics link with enhanced resilience towards rainy weather conditions. Through continuous measurement over 3-hours, we demonstrate \(\sim\)4...

Summary:Using time-adaptive probabilistic shaped 64QAM driven by a simple SNR prediction algorithm, we demonstrate \(>\)450 Gbps transmission over a 55-m free-space optics link with enhanced resilience towards rainy weather conditions. Through continuous measurement over 3-hours, we demonstrate \(\sim\)40~Gbps average bit-rate gain over unsupervised fixed modulation.
