光通信行业的景气度至少还能看到2027—2029年 1. 目前1.6T、800G仍是核心增量,2027年1.6T订单预计较2026年翻数倍,800G至少翻倍;到2028年,2.4T放量、更多CSP导入1.6T,以及CPO带来的新需求,将接力成为增长动力,而800G则逐步被1.6T替代。单波400G技术预计在2028—2029年成熟,届时将进一步推动带宽升级。 2. 技术路线方面,一个比较重要的判断是:CPO不会很快彻底替代可插拔。 可插拔、NPO、CPO未来很长时间会并存。可插拔在scale out场景仍有较长生命周期;NPO也并非短期过渡产品,二代、三代将向2.5D、3D封装演进,并有望在2027年下半年开始部署;CPO虽然性能更好,但目前仍面临可靠性、维护、成本以及产业链成熟度等问题,真正大规模应用预计要到2030年以后。 3. 供应链依然是行业的重要瓶颈。尤其是2026—2027年的1.6T DFB以及DSP等关键物料,公司通过预付款、长期协议、战略投资等方式提前锁产能,但随着需求持续增长,供应偏紧的状态短期难以完全缓解。 4. 竞争壁垒也比市场想象中高。光模块并不是简单的“组装生意”,硅光、薄膜铌酸锂、相干技术、高频电路和先进封装等环节都存在技术门槛,同时客户认证周期长、供应商数量有限,形成较强的客户壁垒。 最后,技术、客户和供应链壁垒让头部厂商仍具优势。除了美股的一些龙头以外,上面的这些逻辑我认为也适用于大A。 $LITE $COHR $AAOI $FN

Citibank TMT: "lasers and optical fibers are being positioned as the "next HBM." I've been talking about lasers like $LITE / $AAOI since 2025... and architectural shifts toward CW, ahead of the current industry consensus. And fully agree with Lightmatter/Citi. Just for reference: For lasers: $LITE / $SIVE / $AAOI / $COHR / $MTSI / Furukawa / Sumitomo are your better known ones. For fiber: $GLW / Furukawa / Fujikura / Sumitomo are your more well-known exposure (obviously a lot more in the supply chain) *disclosure, personal exposure to theme With added commentary that: "Tight supply conditions will support a scarcity premium for these assets." We're already seeing price hikes with lasers as seen with $SIVE channel checks at CIOE 2026 Shenzhen today + $LITE commentary from earnings. So I think the 2027–2028 photonics supercycle will look a lot like memory did in 2025–2026. Especially as optical content/GPU-ASIC goes up significantly per Goldman Sachs revised estimates...
