| 摘 要： | 采用码分复用(OCDM)与波分复用(WDM)相结合的技术可以构成多跳网，其关键技术是波长和地址码的转换，但转换中存在着电子瓶颈．提出了一个全光的地址码转换方案，该方案依赖于光硬限幅器技术，适用于时域编码的OCDM系统．分析了影响该方案工作性能的各项因素，并利用Gaussian近似，得到了码字转换差错率的边界与光硬限幅器的阈值之间的关系，以及该光码字转换方案对网络端到端误码率性能的影响．

| Abstract: | OCDM/WDM multi-hop optical networks can be realized by applying OCDM into WDM multi-hop optical networks. The address code conversion is a key technology in this network. This paper proposed an all-optical scheme of code conversion, which depends on optical hardlimiter and suit time coding OCDM system. Then, some factors that will impact the performance of converter were discussed. Finally, the conversion error probability and end-to-end BER were calculated when this conversion scheme is used in OCDM/WDM multi-hop networks. |
