摘　　要：评述了目前光CDMA系统的研究领域和一些最新的实现方案,对基于SPECTS的光CDMA技术方案进行了分析,研究了影响光CDMA系统实现的主要因素,对方案实际实现中面临的技术难点进行了讨论,提出了多址干扰和安全性是近期OCDMA应用可行性的主要技术障碍.The current OCDMA research areas and some optical CDMA schemes were reviewed. The spectral phase encoded time spreading （SPECTS） OCDMA technique, which exhibits a good prospect for practical applications in future broadband access networks, was introduced, and some limitations that may affect the implementation of OCDMA systems were investigated. The project of developing actual OCDMA system was proposed and analyzed. The results show that multiple access interference （MAI） and confidentiality are the main barriers as an enabling technology of optical LAN in the near future.
