摘要
提出了一种新的基于环形拓扑结构的光码分多址(OCDMA)接入网络,对网络的模型、性能进行了分析。设计了一个基于周期性频域编码技术的环形网络的自干扰调制方案,并对其进行了分析和讨论。试验证明:该方案允许所有用户同时通信并且能提高网络的灵活性和效率。
A new ring topology based on optical code division multiple access(OCDMA) networks is proposed, and its network model and performance are analysed. Based on ring network, a self-interference modulation system was designed. Through analysis and discussion, it proves that the network allows all users to communicate at the same time and it can increase the network efficiency and flexibility.
