At the China International Optoelectronic Expo (CIOE) in 2026, Xinsejie officially launched a 400Gbps back-illuminated PIN photodetector chip. As a core receiving component, this product aims to support the evolution of global AI computing optical interconnection to a rate of 3.2T. The chip breaks through traditional bottlenecks in bandwidth, efficiency, and saturated current through charge compensation technology, and adopts an integrated design for back lenses to reduce manufacturing costs and yield risks. Relying on IDM’s full-chain self-research capabilities, Xinsejie controls the entire value chain from epitaxial wafer development to testing and packaging, and has established a global delivery system covering six industrial bases in Shenzhen, Xuzhou, Bengbu, Singapore, Malaysia, and Thailand. Currently, the company has developed a product matrix covering the entire rate range from 2.5Gbps to 400Gbps, and all products meet international reliability standards such as TelcordiaGR-468-CORE and automotive certification requirements like IATF16949.
