摘　　要：针对光谱相位编码光码分多址系统(OCDMA)的信息侦听技术进行了研究。利用Optisyslem3.0(光通讯系统仿真软件)和Matlab7.1搭建光谱相位编码OCDMA系统软件分析平台,提出用户地址码字拦截模型。通过仿真分析可以看出该窃听模型在多相编码下能有效地破译用户地址码字,实现对整个系统的信息窃听,可见光谱相位编码相干OCDMA系统的安全性值得进一步探讨。The information eavesdropping techniques of spectral phase-coded OCDMA system were investigated. The software platform of the spectral phase-coded OCDMA system was built by using the Optisystern3.0 of the Optiwave Corporation and Matlab7.1, the model of user code interception in this system was put forward. The results of simulation based this model indicate that the address code of the user can be deciphered effectively by the eavesdropping scheme, the total system information can be intercepted, the spectral phase-coded OCDMA system isn＇t secure as generally believed.
