摘　　要：提出在光纤入侵探测系统中应用波分复用(WDM)技术,以进一步精简系统架构。该系统将不同干涉子系统通过不同波长加以区分,并利用波分复用技术将不同波长的干涉子系统复用同一干涉模块。在信号接收端,利用解复用的方式,将各个不同波长干涉子系统信号分开,从而获得不同干涉子系统中相对独立的时域信号。Fiber intrusion detection sensor is proposed to simplify the architecture of based on wavelength division multiplexing （WDM） the system. The system uses different wavelengths to distinguish the different interfering sub-systems. WDM technique is used to multiplex the different wavelength interfering sub-system by the same interfering unit. In the receiver of the system, the signal of different wavelength interfering sub-systems is divided by the demutliplexing. Thus, the independent signal of different interfering sub-systems is achieved.
