光通信器件供应商Lumentum Holdings Inc.(LITE)今日盘前大幅下挫5%，延续了前一交易日的弱势表现，引发市场关注。
消息面上，光通信板块整体承压，主要受到市场对AI基础设施资本开支节奏的担忧情绪影响。光模块与高速互连需求高度依赖AI数据中心资本开支，当市场对AI基建投入节奏产生疑虑时，光通信作为上游敏感环节率先承压。在前一交易日，Lumentum已下跌近7%，与Coherent等光通信个股同步走弱，反映出资金正从"AI基建高投入、回报不确定"的硬件叙事转向更为谨慎的定价。
整体来看，板块走势与存储、芯片形成共振，显示AI硬件链条整体进入预期修正阶段。市场开始质疑AI驱动的需求能否在短期内支撑此前过高的估值，供需再平衡预期升温，光通信板块短期受情绪主导明显。
