摘　　要：随着无线接入技术的飞速发展,人们对宽带网络容量与速度的要求也与日俱增,由此,光纤与微波的结合技术逐步走进人们的视线。在此基础上就光倍频(OFM)技术中微波副载波产生方法进行了一些探讨,研究了基于强度调制器的OFM技术的实现,重点分析了激光相位噪声和扫描相位噪声对系统性能的影响,最后对该技术实现的微波副载波在ROF系统中采用单模光纤传输进行了性能检测。With the rapid development of wireless access technologies,the requirements of broadband network capacity and speed are increased. Thus,the technology combining fiber with microwave attracts people′s attention. On this basis,the microwave subcarrier generation method in OFM technology is investigated. The implementation of OFM technology based on intensity modulator is researched. The impact of laser phase noise and sweep signal phase noise on the OFM System is analyzed emphatically. The singlemode fiber transmission of microwave subcarrier in the ROF system was detected.
