$LITE 的投资逻辑:AI 领域的隐形垄断。 Lumentum 今年迄今上涨 316%,但到 2027 年可能上涨 1000%+。 美光 ($300B) 或台积电 ($1.5T) 位于每个部署的 TPU/GPU 中心。 但 $LITE 也是如此,而其市值仅为 $26B。 在谷歌的每一个 TPU 中,$LITE 为其市值创造了惊人的利润。 这是因为它是光路交换 (OCS) + 光网络的标准。 它也存在于: - $NVDA Blackwell - $AMZN Trainium - 以及其他超大规模云服务商的 ASIC 中。 Lumentum 位于光子学芯片部署的“神圣三位一体”中。 对于每笔 TPU 资本支出,$LITE 占据 8-12%。对于每个 Nvidia GPU,$LITE 占据 ~2-3%(在 InnoLight 和其他公司之间分配,所以计算有点复杂)。 仅针对 NVDA GPU 部署的 BOM 粗略估算: NVIDIA Blackwell (GB200): HBM 内存:~50–55%(SK 海力士主导,美光,三星) 逻辑(GPU 裸片):~25-30%($TSM 4NP) CoWoS 封装:~13-18% $TSM 光网络:~3–5%(InnoLight, Lumentum, Coherent) PCB/电源:5% 谷歌 TPU “Ironwood” TPU v7: HBM 内存:38-42% 三星 / SK 海力士 逻辑裸片:TSM ~28-33% 设计/I.O:8-10% 联发科 光网络:10-14%($LITE 主要,$COHR 次要) 光交换:2-4% $LITE $LITE 估计的总集群份额:~8–12% 仅供参考,谷歌的“光”BOM 份额(8–12%)是一个异常值,源于其独特的光路交换 (OCS) 垄断。 粗略估算: 到 2027 年谷歌 TPU 支出 $40B。$LITE 占据 10%(30-40% 利润率),仅来自谷歌的自由现金流超过 $1.5B,仅其主要客户就带来 17 倍市盈率。(分析师在预测 TPU 支出增长时可能严重偏离。) 这甚至不包括其在 $AMZN Trainium、$NVDA Blackwell、$MSFT Maia 和其他芯片部署中的份额。 $LITE 目前位于每个 TPU/GPU 未来芯片部署的中心,并从中分得一杯羹。 唯一的 downside 是,虽然他们现在是明确的市场领导者,但 $AVGO 和 $COHR 很可能在 2027-2028 年准备好竞争。然而…… 人们说“$26B,历史新高,为什么现在买”。 这就是原因。他们参与了未来每一个部署的 TPU/GPU/ASIC。 如果谷歌 TPU 和其他芯片支出增加,且 LITE 从每个美元支出中占据 2-3%(来自 $NVDA, $AMZN, $MSFT)或 8-12%(来自 $GOOGL),$LITE 最终很容易超过 $60B+。

英文原文

The $LITE thesis: The hidden monopoly in the AI. Lumentum is up 316% YTD, but might be 1000%+ by 2027. Micron ($300B) or TSM ($1.5T) sit in the center of every TPU/GPU deployed. But same with $LITE, but it's a $26B MC. In Every, Single, TPU from Google, $LITE makes unbelievable amounts of profit for their marketcap. That's because it's the standard for Optical Circuit Switching (OCS) + optical networking. It's also in - $NVDA Blackwell -$AMZN Trainium - and other hyperscaler ASICs. Lumentum sits in the holy trinity of every single chip deployment for photonics. And for every TPU capex spent, $LITE takes 8-12%. For every Nvidia GPU, $LITE takes ~2-3% (split between Innolight and some others, so the math gets a bit complex). But some napkin math on NVDA GPU deployments alone for BOM: NVIDIA Blackwell (GB200): HBM memory: ~50–55% (SK Hynix (Lead), Micron, Samsung) Logic (GPU Die): ~25-30% ( $TSM 4NP) CoWoS Packaging: ~13-18% $TSM Optics/Network: ~3–5% (Innolight, Lumentum, Coherent) PCB/Power: 5% For Google TPIU "Ironwood" TPU v7: HBM Memory: 38-42% Samsung / SK Hynix Logic Die: TSM ~28-33% Design/I.O: 8-10% MediaTek Optical Network: 10-14% ( $LITE (primary), $COHR secondary) Optical Switch: 2-4% $LITE $LITE est. total cluster share: ~8–12% Just an FYI, Google's "Optical" BOM share (8–12%) is an anomaly due to their unique Optical Circuit Switch (OCS) monopoly. Just for some napkin math: $40B Google TPU spend by 2027. $LITE captures 10% (30-40% margins), $1.5B+ FCF from Google alone, 17x earnings from just their primary customer. (analysts are probably extremely off with projecting TPU spend scaling). Not even including their split from $AMZN Trainium, $NVDA Blackwell, $MSFT Maia, and other chip deployments. $LITE is in the center of every single TPU/GPU future chip deployment for now and takes a cut. The only downside is they're the clear market leader now, but $AVGO and $COHR are likely set up to compete by 2027-2028. However... People say "$26B, ATH, why are you buying now". This is the reason. They're involved in every future single TPU/GPU/ASIC deployed. $LITE could end up easily over $60B+ if Google TPUs, and other chip spend ramps up and LITE takes a 2-3% (from $NVDA, $AMZN, $MSFT) or 8-12% cut (from $GOOGL) for every single dollar spent.
