摘　　要：介绍了可见光通信技术的发展历史及研究现状。基于带宽拓展技术搭建了1 W荧光型LED做光源、PIN光电二极管做探测器、单路速率610 Mb/s的实时传输演示系统,该系统在传输距离为6.2 m时的误码率为3.48×10^（-5）。在此基础上搭建了荧光型LED为光源、PIN光电二极管做探测器的、双向100 Mb/s无线光上网演示系统。The development history and status of visible light communication technology are introduced. Then two latest achievements are reported. A 500 Mb/s real-time visible light communication system is reported, which, based on bandwidth expanding technology, uses a 1 watt fluorescent type LED as light source and PIN photodiode as detector, reaching a system bit error rate （BER） of 3.48×10-5 over a 6.2 meters transmission distance. Also reported is a new type of symmetrical 100 Mb/s VLC Ethemet system employing a 1 watt fluorescent type LED and PIN photodiode as devices, too.
