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 . Multi-hop networks can be formed by the combination of OCDM and WDM, and the key technology is the wavelength and address code conversion, but there is an electronic bottleneck in the conversion.An all-optical , This scheme relies on the optical hard limiter technology and is suitable for the OCDM system in time domain coding.The factors that affect the performance of the scheme are analyzed and the error rate of the codeword conversion is obtained by Gaussian approximation And the threshold of the optical hard limiter, and the effect of the optical codeword conversion scheme on the performance of the network end-to-end bit error rate.
