en.Wedoany.com Reported - On June 3, Guanglian Xinke, a Chinese startup in the optical interconnect sector, announced the completion of its Series A funding round of nearly 500 million yuan, setting new records for valuation and cumulative financing among industry startups. This round was co-led by Gaorong Capital, Lenovo Capital, and Cornerstone Capital, with follow-on investments from industrial capital and individual entrepreneurs including GLP Hidden Hill Capital, Renai Capital, and Xinhe Capital. Existing shareholders such as Junlian Capital, Sequoia China, Hillhouse Ventures, Zhenzhi Capital, and Shangshi Capital made additional oversubscribed investments.
Guanglian Xinke operates in the optical interconnect (OIO) sector, which is becoming a closely watched underlying technology area for capital in AI computing infrastructure. As large model training, inference clusters, and high-performance computing systems continue to expand, the computing bottleneck is no longer limited to individual GPUs, accelerator chips, or server nodes. Data transmission efficiency between chips, boards, and cabinets now directly impacts overall computing utilization. Traditional electrical interconnects are approaching engineering limits in bandwidth, latency, power consumption, and signal integrity. Optical interconnects aim to bring optical transmission capabilities closer to chips and computing nodes, offering higher bandwidth and lower energy consumption to meet the internal interconnect needs of next-generation AI data centers. The additional investments from multiple leading investment institutions and industrial capital indicate that OIO is transitioning from a cutting-edge technology concept to a new phase where financing, R&D, and industrialization verification advance in parallel.
This funding round, approaching 500 million yuan, is a landmark for similar early-stage projects in China.
From the perspective of the investor structure, new shareholders include market-oriented institutions such as Gaorong Capital, Lenovo Capital, and Cornerstone Capital, as well as capital with industrial synergy like GLP Hidden Hill Capital and Xinhe Capital. Existing shareholders Junlian Capital, Sequoia China, Hillhouse Ventures, Zhenzhi Capital, and Shangshi Capital continued with oversubscribed follow-on investments, suggesting that investors view Guanglian Xinke not merely as a single-chip startup but as a platform player in the AI computing interconnect architecture. For OIO technology to enter large-scale application, it must simultaneously address multiple challenges including optoelectronic integration, packaging, yield rates, heat dissipation, system adaptation, and customer validation. The increased capital will provide longer-term support for the company's subsequent R&D investment, team expansion, sample validation, and industrial chain collaboration.
Against the backdrop of AI computing centers moving toward larger-scale clusters, interconnect capability is evolving from a supporting component to an integral part of system performance. As the number of GPUs continues to increase, data scheduling between nodes, model parallel training, memory access, and computing coordination will all amplify the importance of interconnect technology. With OIO as its entry point, Guanglian Xinke has the opportunity to create new technological connections among optical modules, silicon photonic chips, advanced packaging, AI servers, and data center networks. For China's semiconductor and computing infrastructure industry, the value of such companies lies not only in securing a large funding round but also in their attempt to advance optical interconnect capabilities into more fundamental computing architectures, providing an engineering pathway for a future computing system where "electricity handles computation and optics handles transmission."
Guanglian Xinke still faces industrialization variables such as mass production processes, customer adoption, system ecosystems, and cost control. The OIO sector is in a period of rapid technology validation, and whoever can first bring chip-level optical interconnects from the lab and prototypes into real AI data centers will directly influence their position in the next round of computing infrastructure competition. Following this funding round, Guanglian Xinke is expected to accelerate product development and commercialization validation, while also driving the domestic optical interconnect sector from conceptual hype into competition over industrial delivery capabilities.
