摘　　要：随着多媒体技术的迅猛发展,人们对信息需求量的不断增加,目前的无线频谱资源已经无法满足人们的需求。利用ROF(光纤无线电)技术进行通信,能为系统提供更大的容量,ROF技术必将在未来网络融合中发挥巨大的作用。在基于光外差技术的ROF系统传输链路上分析了随着传输光纤的距离的变化,在接收端产生的毫米波信号的变化。在发射端主、从激光器频率差改变的情况下,接收端产生的毫米波信号的变化。With the rapid development of multimedia technology, and the increasing demand for information, the current radio spectrum could not completely satisfy the needs of people. ROF technology could provide fairly great capacity for the system communications, and will play an imporrtant role in future network convergence. Both the change of millimeter wave signal with the distance change of optical fiber transmission produced at the receiving end and the change of millimeter wave signal with the frequency difference change based on the optical heterodyne technology of ROF system transmission link are analyzed in detail.
