摘　　要：光正交频分复用技术是一种将电域正交频分复用与光纤通信技术相结合的新型光通信技术,具有高频谱利用率、有效抵抗光纤链路中的色度色散、偏振模色散和非线性效应等优点,在大容量、长距离光纤通信系统和光接入网中有着广阔的应用前景。介绍了光正交频分复用(O-OFDM)系统的工作原理、结构及其关键技术的国内外研究现状,讨论了O-OFDM应用有待深入研究的技术和问题,展望了O-OFDM技术的发展趋势和应用前景。Optical orthogonal frequency division multiplexing（O-OFDM） technology is a novel optical com- munication technology which combines electrical OFDM technology and optical fiber communication tech- nology. O-OFDM will be widely employed in the large-capacity and long-haul fiber-optic communication systems and optical access networks because of its high frequency efficiency, effective resistance to the chro- matic dispersion, polarization-mode-dispersion and non-linear effects. The principles, structures and key technologies for O-OFDM at home and abroad are introduced. The technologies and theoretical problems to be studied for O-OFDM applications are discussed and moreover, the future development trends and application prospects of O-OFDM technologies are penetrated.
