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 micro?wave 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 emphati?cally. The single?mode fiber transmission of microwave subcarrier in the ROF system was detected.
