1. **会议与主题**:2025年1月28-30日于圣克拉拉会议中心举办,主题为基于硅光调制器的1.6Tbps线性直驱系统设计与性能评估。 2. **核心优势**:1.6T LPO模块采用224Gbps/lane硅光调制器(SiP),功耗低于DSP模块(32瓦),成本低于EML/TFLN,产业链成熟。 3. **关键挑战**:需解决调制器啁啾、多路干涉(MPI)、MZM非线性及系统反射问题,PIC带宽需>45GHz以保证BER<1e-9。 4. **测试结果**:在500m光纤中,光功率>0dBm时BER<1e-8;>2.16dBm时BER<1e-7;TP2眼图ER=4.162dB,TDECQ=4.03dB。 5. **结论**:SiP调制器是1.6T LPO最优选择,合理设置PIC带宽可提升系统性能。
**1.6T为何选LPO?** **SiP调制器优势何在?** **LPO系统如何优化?**
