Lumentum Holdings Inc.（股票代码：LITE）今日盘中股价大幅下挫，跌幅达7.92%，引发了市场的高度关注。
消息面上，独立研究机构SemiAnalysis发布报告指出，共封装光学（CPO）技术的大规模量产时间可能推迟至2028年甚至2029年，且系统级良率仅约19%，远未达到商业化量产标准。这一消息持续压制了光通信板块的整体市场情绪，成为股价下跌的主要导火索。
此外，当前通信设备板块表现普遍疲软，板块内的联动效应显著。同板块的Applied Optoelectronics、诺基亚及Ciena科技等公司股价也出现不同程度下跌，进一步加剧了Lumentum的调整压力。尽管公司管理层曾试图以近封装光学（NPO）等新技术叙事提振信心，但市场对CPO前景的根本性担忧仍未消除。
