Nations Technologies' stock hit the daily 20% limit after confirming its CPO (co‑packaged optics) strategy and existing MCU technology for high‑speed optical modules. The company said its N32H493 MCU series , designed for 800G and 1.6T optical transceivers, is already in customer validation – providing near‑term revenue.

For the long term, Nations is leveraging its MCU platform to develop control chips for CPO , the next‑gen optical interconnect that integrates optical engines directly with switching silicon to cut power, latency, and signal loss – a critical AI data center trend.

The company believes its existing R&D framework for high‑speed optical modules can be directly repurposed for CPO, with no technological gap, positioning it to benefit from both current module demand and future co‑packaged optics adoption.
