日本InP出口管制或致光模块产能瓶颈，作者减持相关风险敞口。

中文翻译

我们正目睹市场的第三阶效应，$LITE、$AAOI 及光子学板块遭遇血洗，跌幅超 10%。原因多重，包括 SanDisk 下跌 10%+ 引发的板块拖累及其他抛售。但我的细微观点是：由于日本出口管制，整个日本供应链的磷化铟(InP)库存/产能可能耗尽，而这正是西方大规模光模块建设所必需的。我不会将 $COHR 与其他光子学玩家混为一谈，但他们已面临产能紧张，且受住友、JX 影响，情况可能恶化。这将导致 $LITE 等缺乏 InP 来为 $GOOGL TPU Ironwood 等生产光模块的公司产能受限。然而，若出现以下情况，这种影响将被抵消，我们可能看到持续反弹： -> 下游如高带宽内存(HBM)的定价溢价抵消产品短缺。 -> 日本以某种方式解除 InP 出口禁令（不太可能）。 -> 若 $AXTI 在获得 1 亿美元融资翻倍产能后，能向西方供应商大规模交付衬底，事情将顺利进行。总之，我想从供应链角度提供另一种视角，因为鲜有人评论这一点。鉴于本周看到的出口管制风险及 $AXTI 的新垄断瓶颈，我个人已移除部分光模块敞口风险。但我不是空头，不会利用这一点。我对整体板块极度看好，但对光子学玩家（是风险厌恶抛售延续还是反弹）的走势毫无头绪。

英文原文

We’re seeing third order effects in markets with $LITE, $AAOI, and photonics having a bloodbath, dropping 10%+. It’s multifaceted, with sector drop from Sandisk -10%+ and others selling off as well. But my nuance take is that the entire Japanese supply chain will likely run out of InP inventory/capacity from Japanese export controls, required for the western optical buildout at scale. I wouldn’t quite lump $COHR in with the other photonics players but while they’re already capacity strained, it’s likely going to get worse with Sumitomo, JX affected. This would capacity strain $LITE and others who would lack the inp to produce opticals for $GOOGL TPU Ironwood and others. However this would be offset and we might see a continued rally if -> pricing premium downstream like HBM would offset any product supply shortage. -> Japan manages to remove the export control InP ban in some way (unlikely) -> if $AXTI delivers the substrates at scale to western suppliers (after their $100m funding to double capacity), things will proceed. That being said just wanted to offer another perspective on the drop since I haven’t really seen anyone comment on this from the supply chain angle. I personally removed some optical exposure risk after seeing the supply chain vulnerability this week from export controls and the new monopolistic bottleneck by $AXTI. But I’m not a short seller so I wouldn’t take advantage of it. I’m extremely bullish on the overall segment, but no clue what’s going to happen (whether risk-off selloff continues or rebound) for photonics players.
