摘　　要：对基于光纤码分多址(OCDMA)技术的全光网进行了研究。分析了OCDMA技术应用于全光网的优点、多用户的可扩展性、好的保密性等。给出了OCDMA应用在全光网的硬件结构,重点阐述了光纤的选择、设计了光收/发模块以及基于系统集成设计的可调光编/解码器。探讨了全光网具体实现中存在的一些问题,得出结论OCDMA技术是实现全光网传输的较好选择。It investigates the technology of optical CDMA(OCDMA)using in all optical networks. It gives its using merit, security and reality of multi-user. It gives the structure of hardware of OCDMA technique using in AON.It discusses the choice of fiber and designs the bright E/O and O/E modules, and also designs the light encoder/decoder based on system integration technique. At last it discusses some problems in realization of AON using by OCDMA to have a conclusion that the OCDMA technique has an extensive using in all optical networks.
