中文翻译

光子超级周期已经来了。 $NVDA 正在带头把下一次飞跃推向 CPO 和硅光。 而我们现在离拐点还很近,供应链里的瓶颈,比如 Soitec($SOI)或者 Sivers($SIVE),都已经开始显现。 “NVIDIA 对 Spectrum-X 交换机和 co-packaged optics 的更新,是一个重要时刻,说明硅光已经成为下一代 AI 基础设施的核心。” 尽管系统扩展长期依赖铜互连,但公司现在已经把光子放到了未来平台的核心,包括 Vera Rubin Ultra。 这种转变预计将支撑越来越复杂的配置,比如 NVL576,以及未来像 Kyber NVL1152 这样的架构。” “Nvidia 已经在量产 Spectrum-X Photonics,也就是 co-packaged optics(CPO)以太网交换机。 公司还宣布了 Quantum-X Photonics InfiniBand 交换机,它通过自有的 scale-out 互连,每秒可提供高达 800 Tb 的带宽。” 虽然铜依然重要,但它已经无法单独承受 AI 规模需求。 NVLink8 CPO 大概是最大的信号,因为 $NVDA 也把硅光带进了它的 scale-up NVLink 互连,而不仅仅是 scale-out 网络。 scale-out 的 CPO 现在 / 2026 年已经在出货,NVLink scale-up 的 CPO 也很快会到来。 范式已经改变,AI 基础设施的瓶颈现在正正式由“光”来解决。 市场只差时间去发现这些供应链中的瓶颈,然后再把它们计价进去。

英文原文

The Photonics Supercycle is here. $NVDA is spearheading the next leap into CPO & Silicon Photonics. And we’re only near the inflection point with chokepoints in the supply chains like Soitec ( $SOI ) or Sivers ( $SIVE ). “NVIDIA’s update on the Spectrum-X switch with co-packaged optics is an important moment, confirming that silicon photonics is central to next-generation AI infrastructure.” Despite a long-standing reliance on copper-based interconnects for scale-up systems, the company is now placing photonics at the core of its future platforms, including Vera Rubin Ultra. This transition is expected to support increasingly complex configurations, such as NVL576 and future architectures like Kyber NVL1152.” “Nvidia is already in production with Spectrum-X Photonics, which is co-packaged optics (CPO) Ethernet switch. The company also announced the Quantum-X Photonics InfiniBand switch, which delivers up to 800 Tb per second of scale-out throughput using its proprietary scale-out interconnect” Although copper is important, it can no longer alone can no longer handle AI-scale demands. NVLink8 CPO is probably the biggest signal with $NVDA also bringing silicon photonics into its scale-up NVLink interconnect, not just scale-out networking. CPO for scale-out is shipping now/2026, CPO for NVLink scale-up arrives soon. The paradigm has shifted, and the bottleneck of AI infrastructure is now officially being solved by light. It’s only a matter of time before markets find these chokepoints in the supply chains. Then price them in.
