摘要 近年来,由于正交频分复用(orthogonal frequency division multiplexing,OFDM)技术具有独特的优势,已经在无线电领域得到广泛应用,并开始被引入光通信中.目前,对于光正交频分复用(optical OFDM,OOFDM)技术的研究,主要集中在离线实验分析和基于全局时钟的实时分析,提出了一种基于异步时钟的高速实时光OFDM收发系统,通过实验实现了在25 km标准单模光纤(single-mode fiber,SMF)上可实时传输2.5 Gbit/s光OFDM信号,误码率小于1.2×10^(-5). As orthogonal frequency division multiplexing（OFDM） has unique advantages,it has been widely used in radio communications.In recent years,OFDM has been introduced into optical communications. Until now,studies of optical orthogonal frequency division multiplexing（OOFDM） are mainly concentrated on offline experimental analysis and based on real-time analysis with the global clock.This paper demonstrates a high-speed real-time optical OFDM transceiver system based on asynchronous clock transmitting 2.5 Gbit/s 16-QAM-encoded OOFDM signals over 25 km standard single-mode fiber（SMF）.The bit error rate is less than 1.2xl0＂5.
