- English · 原文@SaiseiInvesting No, 0 clue why people invest in those types of ETFs. - You have the most basic names you can buy yourself like $LITE / $COHR as heaviest weights, where they take management fees. - Names not adjacent to AI DCs.中文 · 翻译@SaiseiInvesting 不，完全搞不懂为什么有人会买那种ETF。 - 里面最重的仓位就是些你自己就能买的普通标的，比如 $LITE / $COHR，它们还要收管理费。 - 还都是一些跟AI数据中心不沾边的公司。
- English · 原文We're in a massive EML bottleneck right now and CW lasers are getting bottlenecked now too. To my knowledge, $COHR is buying EMLs off $LITE because they can't make enough. $LITE is majority allocated to EML, so they can't make enough CW lasers. So they're buying CW lasers off competitors from their ER transcript, (probably Sumitomo, Furukawa and others), which likely feeds into $NVDA contracts. Then $AMD and your hyperscalers need capacity too but we're already in a shortage. Any capacity that comes online would likely be bought, since looks like we're in a shortage for next few years (lumentum already sold out into 2028). Not quite the same as your sk hynix/samsung/micron memory dynamic but there's still a massive moat with EML with probably only single digit amounts of players able to do this.中文 · 翻译现在 EML 产能严重堵塞，CW 激光器也开始卡脖子了。 据我所知，$COHR 正从 $LITE 手里买 EML，因为他们自己产量不够。 $LITE 大部分产线都给了 EML，所以也没余力生产足够多的 CW 激光器。 于是他们（从财报电话会里透露）开始向竞争对手买 CW 激光器——可能是住友、古河等——而这些货源大概率最终流进 $NVDA 的订单里。 然后 $AMD 和你那些超大规模客户也急需产能，但我们早就供不应求了。 现在但凡有新产能上线，基本都会被抢光，因为看起来未来几年都会持续短缺（Lumentum 都已经卖到了 2028 年）。 这和 SK 海力士/三星/美光的存储芯片情况不太一样，但 EML 的护城河依然很深，能做的玩家可能一只手就数得过来。
- English · 原文I've been getting a lot of questions about OE Solutions (138080) recently. Here's my research/thoughts so far on it: They're a small Korean optical transceiver company, similar to $AAOI. And they've become one the few EML players in the world (eg. $COHR, $LITE, Mitsubishi, Source, Sumitomo), with scarce 100G EML laser capacity for 800G/1.6T. OE appears to be trying to make the full transceiver, not just the EML. They also have finished ELSFP CPO products, with UHP CW lasers, which is sampling Q3. Likewise, OE also seems to be building out the full ELSFP, rather than selling CW laser dies, so that's more market share. So you can think of it as Korean AAOI but EML instead of CW, and less capacity/qualifications. And playing catch-up to the rest of the world. However in terms of timelines: 1. 23dBm cooled ELSFP samples start in Q3 2026 2. Sales base for 800G, and 2027 1.6T "full force" 3. Late H2 2027, H1 2028 onward probably their ELSFP enters the volume production. And it seems they're working on 200G EML capability from their investor snipper 2025 OE IR snippet referenced “100GBaud EML / 200G PAM". This seems promising given their IP/demos. ELS has just been unveiled recently, sampling starts Q3. 800G/1.6T Optical transceivers are also likely 2027. So this is basically Korea's sovereign photonics player, playing catchup to $LITE, $AAOI, and the bigger players. (Disclosure: I have positions in OE Solutions (138080). This is fundamental research for informational purposes, not financial advice). As for OE solution valuations: 1. Doesn't seem like there's confirmed customers yet for these growth verticals. 2. Probably not many people understood what they're building toward yet. 3. Yields data kinda uncertain 1. Customers: We're actually in a major EML/CW laser shortage, so any independent capacity will be sought after. I personally don't think they'll have a hard time finding customers here. I would assume anything they make might get bought out and would get extra support from Korea. 2. Institutional support: Probably not much since it doesn't meet threshold for many US institution given MC size + KR listing. I also don't think many people understood what they're building yet. 3. Yields/Capacity: OE's disclosed wafer/module utilization is low (i remember was around 31% underutilized off the top of my head), so there's enough material revenue they can generate before they need to spend on capex. I'm also not sure about EML/CW and other yields. Probably need to go ask the company. Is this some random crap co? No. It's been doing optical transceivers stuff for more than 20Y, has R&D in the U.S. and Netherlands. But their entire AI growth vertical seems to happen next year, and hinges mainly around capacity/yields. And I personally think the EML/CW tech is probably worth a lot more than their current MC, if it were an acquisition target. Especially from a larger player that wanted to vertically integrate EML for pluggables and CW lasers for CPO. Markets are probably waiting on more certainty around qualifications after Q3 sampling or earnings projections announcements. TLDR on thoughts: Some of my friends discussed this last year, was probably way too early. Saw it got many comments 2 months ago, still too early. I still think now is early, but later in Q3-Q4 might be more interesting. I personally think it's a lot higher risk than a major CPO player like $SIVE, that's embedded in Ayar, $JBL, $GFS, and many other hyperscaler suppliers. Which also has Win Semi and others de-risking volume ramp. As OE Solutions looks like a new player trying to build out an $AAOI for the optical transceivers but sovereign EML and CW laser production for CPO products. And there's a lot of answered questions around customers + volume ramp, which presents material risk. But if you believe Korea can build out an 800G/1.6T transceiver EML supply chain and ELSFP with CW lasers. With OE Solutions, it might be worth taking a look into. Still researching the company tho, just initial thoughts.中文 · 翻译最近好多人在问我 OE Solutions (138080) 这家公司。 这是我目前的研究和想法： 这是一家韩国的小型光收发器公司，跟 $AAOI 有点像。 而且他们已经成为全球为数不多的 EML 玩家之一（比如 $COHR、$LITE、三菱、Source、住友），手握稀缺的 100G EML 激光器产能，专门用于 800G/1.6T。 OE 看起来不光想造 EML，还想做完整的收发器。他们已经有了成品 ELSFP CPO 产品，配上 UHP CW 激光器，Q3 开始送样。 同样地，OE 似乎也在整完整的 ELSFP 方案，而不是只卖 CW 激光晶粒，这样能抢到更多市场份额。 所以你可以把它理解成"韩国版的 AAOI"，但用的是 EML 而不是 CW，产能和认证方面还差点火候，目前是在追赶世界其他玩家。 时间线上来看： 1. 23dBm 制冷的 ELSFP 样品，2026 年 Q3 开始送样 2. 800G 的销售基础，2027 年 1.6T "全面发力" 3. 2027 年 H2 末、2028 年 H1 及以后，ELSFP 可能进入放量生产 而且从他们 2025 年投资者简报片段来看，似乎还在搞 200G EML 能力——简报里提到"100GBaud EML / 200G PAM"。考虑到他们的 IP 和 demo，这个方向挺有戏。 ELS 才刚发布不久，Q3 开始送样。800G/1.6T 光收发器大概率也是 2027 年。 所以这基本上是韩国的光子学国家队，正在追赶 $LITE、$AAOI 和那些更大的玩家。 （持仓披露：我持有 OE Solutions (138080) 仓位。这只是基本面研究，仅供参考，不构成投资建议。） 关于 OE Solutions 的估值： 1. 这些增长方向目前似乎还没有确认的客户。 2. 可能没多少人真正理解他们在做什么。 3. 良率数据有些不清晰。 1. 客户方面：现在其实正处于 EML/CW 激光器大缺货周期，所以任何独立的产能都会被抢着要。我个人觉得他们找客户不难。我甚至认为他们造出来的东西可能都会被扫货，还会获得韩国政府的额外支持。 2. 机构支持：可能不多，因为市值小 + 韩国上市，很多美国机构根本够不上门槛。我也觉得没多少人真正理解他们在搞什么。 3. 良率/产能：OE 公布的晶圆/模组利用率很低（我记得大概有 31% 的产能闲置），所以他们在需要砸资本开支之前，光靠现有的产能就能产生可观的收入。 至于 EML/CW 以及其他良率，我也不太确定。可能得直接去问公司。 这是不是一家随便的烂公司？不是。人家做光收发器已经超过 20 年了，在美国和荷兰都有研发。 但他们整个 AI 增长方向看起来要到明年才爆发，而且主要取决于产能和良率。 我个人觉得，如果 EML/CW 技术被收购的话，它的价值可能远超目前市值。 尤其是被那些想垂直整合 EML（用于可插拔模块）和 CW 激光器（用于 CPO）的大玩家收购。 市场可能在等 Q3 送样后的认证结果或者营收预期公告，才敢下定论。 总结我的想法： 去年就有朋友讨论过这家公司，当时可能太早了。两个月前看到评论区热闹起来，依然太早。 我现在还是觉得早，但到了 Q3 和 Q4 可能就会变得有意思起来。我个人认为它的风险比 $SIVE 这种深度嵌入 Ayar、$JBL、$GFS 和一堆超大规模供应商的 CPO 大玩家要高得多。$SIVE 还有 Win Semi 等公司在帮忙摊薄量产风险。 而 OE Solutions 看起来更像是一个新手玩家，想照着 $AAOI 的模式去造光收发器，但走的又是主权 EML 和 CW 激光器路线，面向 CPO 产品。 现在关于客户和量产爬坡的问题还有很多没解答，这本身就有实质风险。 但如果你相信韩国能建立 800G/1.6T 收发器 EML 供应链，以及带 CW 激光器的 ELSFP 方案。 那么 OE Solutions 或许值得一看。我还在继续研究这家公司，目前只是初步想法。
- English · 原文Yes, choosing the right theme is extremely important. Even if $POET doesn't really do anything, it still gets brought up thematically due to $LITE, $COHR, and others. Even if $RDDT outperforms extremely hard, it still gets brought down from $META, $MSFT, $CRM, and other software basket names.中文 · 翻译没错，选对主题极其重要。 就算 $POET 本身没什么动作，它也会因为 $LITE、$COHR 和其他股票而被带到主题上来。 就算 $RDDT 表现极其强势，它还是会因为 $META、$MSFT、$CRM 以及其他软件篮子里的票而被拖下来。
- English · 原文非常感谢中文社区对我最看好股票的投资思路进行的深度剖析！ 总的来说，像 $AAOI 和 $SIVE 这样的激光公司是我个人的最爱，因为它们在拓展营收方面有着极大的想象空间。它们可以不仅仅局限于销售激光器，还能制造完整的光模块 以及各种光引擎或 ELS (外部光源) 组件。 又或者像 $COHR 那样，甚至可以向上游延伸进军衬底制造领域，从而实现垂直整合，并不断提升自身的毛利率和总潜在市场规模 TAM 这其中很大一部分的关键在于要率先精准踩中投资主线，毕竟去年很多人甚至都不觉得“光子学（photonics）”能成为一个真正的热门概念。 而且我认为最会让大多数人感到惊讶的是，我们目前仍处于极其早期的阶段。绝大多数的营收放量（爬坡）要到明年，也就是 2027 年的上半年乃至下半年才会真正开始！ 不过，能看到中文社区大家持续不断的支持，真的让我感觉非常棒。我会尽我所能，不辜负大家给我起的 “白毛股神” 这个称号。中文 · 翻译原推为中文，无需翻译
- English · 原文Other way around, $NVDA bottlenecked the entire industry for EML capacity. And did the same with CW capacity ONCE AGAIN with $LITE, $COHR, and $MRVL (if they have LTA in place with Celestial) I said this a few months ago, we'd see this exact same playbook. But $AMD, $AMZN, $META, and others are just so stupidly slow that they let themselves get bottlenecked. Now there's only a few merchant players like $AAOI, $MTSI, and $SIVE that they all need to fight over.中文 · 翻译反过来看，是 $NVDA 卡住了整个行业在 EML 产能上的脖子。 而且它又干了一次同样的事情——在 CW 产能上，把 $LITE、$COHR 和 $MRVL 也给卡住了（前提是他们跟 Celestial 签了长期协议）。 我几个月前就说过，我们会看到完全一样的剧本。但 $AMD、$AMZN、$META 这些家伙动作慢得离谱，结果让自己也被卡在瓶颈里。 现在只剩少数几家商业玩家了，比如 $AAOI、$MTSI 和 $SIVE，大家都得争着抢。
- English · 原文New reports that $AMD is scrambling for CW laser supply. And is negotiating large-scale purchase orders for CW Lasers to ensure its production capacity is not constrained by $NVDA (Trendforce) Obvious CW laser beneficiaries: - $SIVE (AMD went to GFS for CPO, Sivers reference laser level) - $AAOI (Rosenblatt analyst checks) Lumentum/Coherent are kinda booked out way into 2028 as well. Lumentum is especially constrained for CW capacity already from existing EML contracts (so they probably are buying from Sumitomo/Furukawa and co). Maybe Macom and Japanese giants still have spare capacity. (disclosure, own aaoi/sivers). I predicted this last year and said hyperscalers should go more upstream to secure capacity... at laser levels, epiwafer levels, or even inp substrate levels. To not get bottlenecked by Nvidia.中文 · 翻译最新消息称 $AMD 正在疯狂寻找 CW 激光器供应。 并且正在洽谈大规模购买 CW 激光器的采购订单，以确保其产能不受 $NVDA 限制（Trendforce 消息） 明显的 CW 激光器受益方： - $SIVE（AMD 找 GFS 做 CPO，Sivers 是参考激光级别） - $AAOI（Rosenblatt 分析师的调研确认） Lumentum/Coherent 的产能基本已经排到 2028 年了。 Lumentum 的 CW 产能尤其紧张，因为已经签了很多 EML 合同（所以他们可能正在向 Sumitomo/Furukawa 等厂商采购）。 也许 Macom 和日本巨头还有多余产能。（声明：我持有 aaoi/sivers）。 我去年就预测过，说过超大规模云厂商应该更向上游去锁定产能……在激光器层级、外延片层级、甚至 InP 衬底层级。 这样才能不被 Nvidia 卡脖子。
- English · 原文hmm, i prefer all your upstream chokepoints over $NVDA long term since those will be re-rated the most (nvidia already largest company in the world) pretty sure hyperscaler ASICs would eventually siphon off $NVDA demand like $GOOGL TPU, $AMZN trainium programs. wouldn't be too positive for expontentially compounding revenue growth since hyperscalers were Nvidia's original main revenue stream (even indirect via Neoclouds). But $NVDA's kinda stalling everyone elses buildout by bottlenecking their programs eg. EML/laser capacity agreements years out too. And took stakes in $MRVL / $LITE / $COHR / $INTC etc. making them adopt to $NVDA standards or just owning a large %. So even if they're delaying other programs + their biggest growth vector kinda falls off one day, like how things are shifting already shifting to ASICs for inference. They'll still probably be fine given ownership stakes + will serve companies/countries outside of hyperscaler cash cows (just less revenue)+ made so much before then. But that's probably why p/e keeps going down despite revenues going up, since idk if markets thinks that growth will last forever. Or could be totally wrong and they just keep leapfrogging generation by generation + AI pie keeps growing with Jensen's 4T 2030 capex number.中文 · 翻译嗯，长期来看，我更看好你提到的所有上游瓶颈环节，而不是 $NVDA，因为那些东西的估值重估空间最大（英伟达已经是全球最大公司了）。 我相当确信，超大规模云的 ASIC 最终会分流 $NVDA 的需求，就像 $GOOGL 的 TPU、$AMZN 的 Trainium 项目那样。这对指数级复利的营收增长可不太有利，因为超大规模云本来就是英伟达最初的主要收入来源（甚至通过 Neocloud 这种间接渠道也是）。 不过 $NVDA 也在卡别人脖子，拖慢大家的建设进度，比如把 EML/激光产能协议签到了好几年后。而且它还入股了 $MRVL / $LITE / $COHR / $INTC 等公司，要么让它们采用 $NVDA 的标准，要么直接拿大头股份。 所以，哪怕它拖慢了其他项目 + 自己最大的增长引擎某天会熄火（就像现在推理已经在往 ASIC 转移了）， 考虑到它手里那一堆股权 + 还能继续服务超大规模现金牛之外的公司和国家（虽然收入会少一些）+ 之前早就赚得盆满钵满，它大概率还是能过得不错。 不过，这大概也是为什么它收入一直在涨、市盈率却持续走低的原因——大概市场也不确定这种增长能不能永远持续。 当然，也可能我完全错了，它们就是一代代持续领先 + AI 蛋糕持续做大，配合 Jensen 说的 2030 年 4 万亿 capex 目标。
- English · 原文@OGCapital25 @Chi_w_wong It's expected Celestial and Lightmatter try and multi source. But maybe for gen-1 my guess is a lot sole source / primary source with $SIVE for the $NVDA CPO NVlink ecosystem. Nvidia has their own program with $LITE and $COHR.中文 · 翻译@OGCapital25 @Chi_w_wong 预期 Celestial 和 Lightmatter 会尝试多源供应。 但可能第一代产品，我猜大多是独家或主供，用 $SIVE 来服务 $NVDA 的 CPO NVlink 生态系统。 英伟达自己也跟 $LITE 和 $COHR 有合作项目。
- English · 原文$SIVE is the most compelling CPO exposure stock to me. Despite the volatility. You probably won’t find something like this again until the next architectural shift in photonics years later. Out of the core laser suppliers, they’re all tens of billions? $AAOI = $15B Furukawa = $26B $MTSI = $29B Sumitomo = $59B $COHR = $73B $LITE = $74B Then there’s $SIVE as one of the core CPO laser chokepoints at $2.3B MC. Earnings are usually confirmation of all the little volume ramp hints like Jabil fireside transcripts for 1.6T LRO. And most returns are typically made before, not after official confirmation is just a rule of thumb.中文 · 翻译$SIVE 在我看来是最有吸引力的 CPO 概念股。 虽然它波动很大。 但你可能要到几年后光子学领域下一次架构变革时，才能再找到这样的标的。 核心激光器供应商里，它们市值不都是几百亿吗？ $AAOI = 150 亿美元 古河电工 = 260 亿美元 $MTSI = 290 亿美元 住友电工 = 590 亿美元 $COHR = 730 亿美元 $LITE = 740 亿美元 然后 $SIVE 作为核心 CPO 激光器瓶颈之一，市值只有 23 亿美元。 财报通常只是确认那些小信号——比如 Jabil 电话会纪要里关于 1.6T LRO 的量产线索。 而大部分收益往往是在正式确认之前赚到的，而不是之后，这只是一条经验法则。
- English · 原文$AAOI is more pure manufacturing scale and I'm extremely bullish on them. So it's more like Furukawa + Innolight in my view? So extremely bullish for revenue ramp. $SIVE is just pure one-of-a-kind IP, where major CPO hyperscaler supplier seems to all use them, like Ayar/Celestial and others. Even $JBL made groundbreaking 1.6T LRO moats with Sivers. Sky is the limit here with Sivers and they can always vertically integrate like $COHR / $AAOI down the road too with capex spend. But their main focus right now should just creating the largest IP moat possible + outsource manufacturing to keep capex light. Can always vertically integrate the assembly, laser fab down the road too. I like them both for different reasons.中文 · 翻译$AAOI 更偏向纯粹的制造规模，我极度看好他们。 所以在我看来它更像 Furukawa + Innolight？因此极度看好其营收增长。 $SIVE 则是纯粹独一无二的 IP，主要的 CPO 超大规模供应商似乎都在用他们，比如 Ayar/Celestial 等。 连 $JBL 都与 Sivers 在 1.6T LRO 上建立了突破性的护城河。 Sivers 的上限是天花板，未来他们也可以像 $COHR / $AAOI 那样通过资本开支实现垂直整合。 但他们目前的主要重点应该是尽可能打造最大的 IP 护城河 + 将制造外包以保持轻资本。 以后随时可以垂直整合组装和激光器制造。 我因为不同的原因看好这两家。
