Distributed data centres rely on high-speed optical interconnects to support large-scale AI. However, as transmission speeds continue to increase, signal distortion, latency and power consumption pose major challenges. The OSP developed by the CUHK-led team can correct distortions in real time before the optical signal is converted into an electrical signal. With a latency below 60 picoseconds and extremely low energy consumption, it can help increase transmission capacity and accelerate AI training across data centres.
