## AI 摘要

SemiAnalysis 分析称，NPO 是从可插拔光模块向真正 CPO 过渡的临时方案，兼具 CPO 大部分优势，同时规避其生产与可靠性难题。NPO 支持现场更换、故障影响范围限于单个模块，且光学引擎与交换 ASIC/XPU 分开封装，组装更简便。

## 正文

NPO presents an interim solution under the transition from pluggable to true CPO. NPO has certain benefits over CPO that bypass current production and reliability challenge of CPO, while maintaining most of the benefits CPO provide.

Pros:

🟠 Better serviceability (field replacable)
🟠 Lower blast radius (blast radius limited to the individual NPO module)
🟠 Easier assembly (Optical Engine are packaged separately from the Switch ASIC/XPU)

Let's look at how NPO differentiate from CPO architecturally. (1/3)🧵
