During the 2026 Yunqi Conference, Xizhi Technology launched a 3.2T/6.4T SNPO silicon optical chip. The chip complies with NPO specifications led by Alibaba and ODCC. At this year's Yunqi Conference, Alibaba Cloud released an optical interconnection scheme defined by the Panjiu Super Node server based on the SNPO interconnect architecture. The interface design is compatible with 112G/224G SerDes and supports evolution to 448G. Meanwhile, the 3.2T/6.4T SNPO silicon chip launched by Xizhi Technology integrates transceiver and receiver. It realizes 16 independent 53/106 Gbaud modulator channels and 16 independent 53/106 Gbaud detector channels on a single chip. The modulator and detector bandwidth both exceed 55 GHz.
