高速可见光通信关键技术综述
Review of key technologies for high-speed visible light communication
摘要
Abstract
To meet the demands for high-speed,low-latency,and large-capacity transmission in data center interconnects and high-performance computing,this paper reviews the research progress on transmitter devices,receiver devices,and coding and modulation technologies in high-speed visible light communication(VLC)systems,and introduces a wavelength-division mul-tiplexing(WDM)visible-light interconnect prototype based on a multi-wavelength laser array.By employing bit-power load-ing and neural network post-equalization techniques,the prototype achieves a transmission rate of 500 Gbit/s,with the bit error rate(BER)of all 40 wavelength channels remaining below the 7%hard-decision forward error correction threshold.These find-ings indicate that the synergistic optimization of high-speed transmitter devices,high-bandwidth receiver devices,and ad-vanced coding and modulation technologies is the critical pathway for advancing VLC toward high-capacity optical intercon-nect applications.关键词
