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.%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.
