**Huawei, China Mobile, Baidu Unveil Groundbreaking China’s First NPO Optical Interconnect Standard**

*Introduction*
In a move that could reshape the backbone of China’s AI infrastructure, Huawei, China Mobile, Baidu and more than 20 domestic tech firms and research institutes have jointly introduced OPEN NPO – the nation’s first multi‑source agreement for near‑packaged optics (NPO). The initiative aims to create a unified specification for high‑speed optical interconnects that will link AI supernodes, data‑center racks and large‑scale computing clusters. By aligning hardware vendors, telecom operators and software developers under a single standard, the consortium hopes to eliminate compatibility bottlenecks that have slowed the rollout of next‑generation AI workloads.

*Key Developments*
The OPEN NPO framework defines mechanical, electrical and optical parameters for transceiver modules that sit within a few millimetres of the ASIC or switch silicon. Core specifications include a 100 Gbps per lane data rate, support for PAM‑4 modulation, and a standardized form factor that enables hot‑swap capability without redesigning the host board. Huawei contributed its silicon‑photonic engine expertise, China Mobile provided field‑trial data from its 5G‑edge sites, and Baidu supplied AI‑training benchmarks that will be used to validate latency and power‑efficiency targets. Over twenty additional participants—including chipmakers, optical‑module manufacturers and universities—have signed the memorandum of understanding, agreeing to submit compliance test results within the next twelve months.

*Industry Analysis*
Analysts note that the lack of a common NPO spec has forced Chinese data‑center operators to rely on proprietary solutions, driving up costs and limiting scalability. By establishing an open, multi‑source standard, OPEN NPO could reduce
