摘要
为了满足人们对于高带宽业务的需求,针对10G-EPON网络技术进行了分析,并提出了突发模式光收发模块的设计方案。首先对10G-EPON的网络拓扑结构、波段的分配及其对突发模式光收发模块的要求作了介绍,然后提出了1G/10G双速率10G-EPON系统模型,设计了ONU端和OLT端的系统框图。通过对比分析,提出针对双速率信号进行电域分离的方法,解决了设计难点。最终的设计结果对于下一阶段的制备和测试以及10G-EPON的推进有着一定的指导意义。
In order to meet the demand for high bandwidth services,the network technology of 10G-EPON is analyzed in this paper,and the design scheme of burst-mode optical transceiver is proposed.The network topology,bandwidth allocation for 10G-EPON and its requirements for burst-mode optical transceiver are first introduced,then the dual-rate 1G/10G EPON system is presented and block diagrams for OLT and ONU are designed.By comparing and analysis,the method of the separation of dual-rate receiving signal in electrical domain,is proposed.The result provides direct guidance to the next stage of preparation,testing and the advance of 10G-EPON.
