摘要

利用简单信信比预测算法驱动的时间自适应概率形64QAM，我们演示了在55米自由空间光学链路上传输$>$450 Gbps，并增强了对雨天条件的弹性。通过超过3小时的连续测量，我们证明了在无监督固定调制下的平均比特率增益为$ $40~Gbps。

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