$NVDA 去年锁定了大部分光模块(EML)产能，导致其他超大规模云服务商面临巨大瓶颈。然而，光子学整体是一个材料问题，最上游的材料由中国控制。这并非英伟达能单方面决定的。不过，他们通常是最早布局的，这给 $META、$MSFT、$AMZN、$GOOGL 留下了更多问题，因此本文指出共封装光学(COWOS)、高带宽内存(HBM)和光子学可能是瓶颈。

英文原文
$NVDA secured most of the EML capacity last year and caused a huge bottleneck for other hyperscalers. However, photonics as a whole is a materials problem, the most upstream materials controlled by China. Not exactly something Nvidia can decide. However, they're usually the first to things and that leaves more problems to $META, $MSFT, $AMZN, $GOOGL afterward, hence the point of the post signaling cowos, hbm, and photonics are probably the bottlenecks.
