Driven by the rapid advancement of artificial intelligence and intelligent computing centers, intra-data-center interconnection bandwidth demand is experiencing explosive growth. 3.2 Tb/s ports are expected to achieve large-scale commercial deployment in the second half of 2028. As the core technical foundation for 3.2T ports, 400G per lane is also a key enabler for next-generation high-speed optoelectronic interconnection solutions such as CPO/NPO and AIDC networking, while posing new challenges to the bandwidth capabilities of active and passive devices as well as signal integrity.

To Address the above‑mentioned industry pain points, more than 20 industry partners including China Mobile, Huawei, Alibaba Cloud, Tencent Cloud and ZTE have jointly launched the 400G per Lane Multi-Source Agreement (MSA) under NIDA. Grounded in 400G per lane electrical interfaces, optical interfaces, signal integrity, modulation and coding, the MSA conducts standardization pre-research with proactive coverage of optoelectronic architecture innovations such as CPO/NPO and AIDC networking. It aims to build industry consensus, establish unified technical roadmaps, achieve multi-vendor device interoperability, and propel the industry toward higher speeds, longer transmission reach, greater reliability, and lower costs.

We cordially invite you to attend the 2026 400G per Lane MSA Achievements Release & High-Speed Optoelectronic Interconnection Workshop. This event will bring together industry organizations, technical experts, academic researchers and ecosystem partners across the industry chain to discuss technical challenges surrounding 400G per lane, CPO/NPO, AIDC networking, and other high-speed optoelectronic interconnection technologies, and to share cutting-edge technical explorations and engineering practices. We look forward to your distinguished participation.
