摘要 研究了接入网中光码分多址/波分多址(OCDMA/DWDM)混合系统影响系统性能的因素,通过理论分析和仿真,得出系统比特差错概率(BER)的半解析表示,最终仿真结果表明,为了满足通信质量,在配置系统时要严格控制同时在线的地址码用户数K,而复用信道数M可在成本允许的范围内灵活选择。初步解决了满足系统正常传输所需要的系统配置问题,为以后实际系统的用户数设计提供了一定的参考价值。 The dements that influence the performance of the OCDMA/DWDM system in access network were investigated. The semi-analytic expression of BER was gotten by theoretical analysis and simulation, and then a perfect configuration which made the transmission in small error rate (〈10^-9 ) was put forward. The results can prolide a reference to the later design in reality system.
