摘　　要：通过对射频光纤传输(ROF)技术的研究,提出了一种采用O-OFDM调制的射频光纤传输-无源光网络(ROF-PON)接入系统方案。主要探讨了基于ROF的DWDM-PON接入系统架构及ROF系统光源调制技术,对光正交频分复用技术应用于DWDM系统长距离传输时的色散问题进行研究,并提出了解决方案。Based on radio over fiber （ROF） technique, an access system solution based on ROF-PON （passive optical network） in which O-OFDM modulation is used was proposed. Both the architecture of DWDM-PON access system based on ROF and the laser source modulation technique of ROF system were discussed. In addition, the problem o! dispersion of OFDM technique applied to long-distance Iransmission in DWDM system was researched and corresponding solution was presented.
