About the session

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 ~40 Gbps average bit-rate gain over unsupervised fixed modulation.
