    Overseas optical chip supply continues to be tight, and domestic manufacturers are achieving breakthroughs.

    算力需求持续井喷，推动数据中心光模块不断向更高速率演进。光通信行业独立研究机构LightCounting于5月28日发布的2025年全球光模块供应商TOP10榜单显示，共有7家中国厂商入围。与制造封装环节的高份额相比，上游核心物料之一的高速率光芯片国产化率仍在低位徘徊。如今，随着海外光芯片供给持续紧缺、国内技术实现群体性突破，这一核心物料正迎来国产替代窗口期。如何将窗口期红利转化为规模化落地的长期优势，成为行业当前面临的核心考验。（证券时报）
