Memory Just Doubled. Is Optical (Up 143%YTD) Market's Next Target?

$Lumentum(LITE)$ surged 8% this week, is up +143% YTD. $COHERENT(COHR)$ added +19% this week and continues to build momentum.

J.P. Morgan just raised LITE's target from $565 → $950. COHR from $245 → $300. Both: Overweight.

Why optical is back in the spotlight this week?

JPM, Goldman, the OFC data: The AI infrastructure buildout is accelerating, not slowing. CPO and OCS are no longer 2028 stories — they're 2H 2026 revenue. The market is still pricing these companies like boring legacy optical hardware companies. That's the mispricing. Memory started repricing six months ago. Optical is repricing now.

  1. Memory prices just confirmed the AI hardware supercycle is real. Samsung reported Q1 earnings that demolished estimates. DRAM pricing: +103% quarter-over-quarter. NAND: +87% QoQ. Goldman Sachs raised Samsung's target to ₩285,000. The memory upcycle isn't a thesis anymore — it's a line item.

  2. The biggest optical components conference of the year (OFC) just ended. OFC is where every major player in photonics shows their roadmap. This year's message was unambiguous: the "future technology" conversations from previous years are now purchase orders. Customers are signing contracts. Capacity is being booked years out.

What is optical module? Why does this matter?

You know how highways get congested when too many cars try to use them at once?

Data centers have the same problem. Millions of AI calculations are happening every second — and all that data needs to travel between chips, between servers, and between buildings at insane speeds.

Optical modules are the solution. Light travels faster. It uses less power. It doesn't generate as much heat.

Every time you use ChatGPT, watch a Netflix recommendation, or ask an AI assistant anything — your request flows through optical modules, probably multiple times.

Optical modules are the highways of AI infrastructure. And right now, those highways are being rebuilt from scratch.

Two technologies you need to know

Analysts keep throwing around "CPO" and "OCS." Here's what they actually mean:

CPO (Co-Packaged Optics) Traditional optical modules sit separately from the chips they serve — connected by short copper wires. CPO moves the optical module directly next to the chip it's talking to. Less distance = less energy lost = faster = cheaper to run.

OCS (Optical Circuit Switching) Traditional data centers use electronic switches to route traffic. OCS replaces those with optical switches — routing data as light, not electrons. Faster reconfiguration, lower latency, lower power.

Lumentum alone is on track to do $400M annualized in OCS revenue by H2 2026 — accelerating to $1B+ annualized in 2027 — backed by a multi-year, multi-billion dollar contract with a single hyperscaler.

Would you add these two optical stocks in your watchlist?

J.P. Morgan's summary in one line: LITE is the higher upside, higher risk bet. COHR is the "buy the whole sector without picking the winning horse" play.

Questions

Q1: Which optical module name looks most interesting to you right now?

  • A. LITE — high conviction on the multi-year CPO/OCS story, willing to hold through volatility

  • B. COHR — broader exposure, more predictable, Nvidia LTA gives visibility

Q2: Are optical modules the next memory — a structural investment theme for the next 2-3 years?

    人工智能基础设施建设正在加速,而不是放缓。CPO和OCS不再是2028年的故事,而是2026年下半年的收入。市场仍然将这些公司定价为无聊的传统光学硬件公司

    至于光模块会不会成为下一个内存,我觉得答案是“会,但节奏更慢”。它不是价格周期驱动,而是渗透率提升+架构升级驱动,一旦进入放量期,持续性反而可能更强。


    结论很简单:这个方向值得放进重点观察名单,但现在更像“刚启动”,而不是“已经走完一半”。

    Lumentum和Coherent的区别也很清晰:前者更像“进攻型”,押CPO和OCS的爆发,弹性大但波动也大;后者偏“平台型”,客户结构更稳,有点类似“买行业beta”。如果要选,我个人会更偏向先看Coherent,再等Lumentum回调找机会。

    内存这波上涨,其实起了一个示范作用。DRAM和NAND价格暴涨,本质上证明AI硬件超级周期已经落地,不再是预期。既然存储可以被重估,那同样卡在瓶颈位置的光通信,被资金接力炒作是很自然的路径。

    之前大家只盯着GPU和内存,但随着训练规模越来越大,瓶颈已经从“算不算得动”变成“传不传得动”。OFC释放的信号其实很关键——CPO、OCS不再是远期PPT,而是已经进入订单和产能锁定阶段。这种从“讲技术”到“签合同”的变化,才是资金真正敢进场的原因。

    这周光学板块突然被重新定价,我觉得核心就一句话:市场开始相信“AI不只是算力问题,而是系统工程”。

    I’m leaning more toward Lumentum Holdings Inc. here. The upside is compelling with CPO and OCS shifting into real 2H 2026 revenue, not just future optionality. This feels similar to early memory re-rating — the market is still catching up to how fast AI-driven demand is scaling. I’m willing to sit through volatility for that potential rerating.

    That said, Coherent Corp. is a cleaner, more balanced play. Its broader exposure and better demand visibility make it more resilient if macro conditions turn volatile, while LITE remains the higher-beta, higher-upside bet.

    Overall, I do think optical modules are becoming a structural theme for the next few years. Signals from Optical Fiber Communication Conference and memory pricing confirm that AI infrastructure demand is now fully translating into real deployment — and capital is just starting to rotate into this layer.
