Guanglian Xinke Secures Nearly 500M RMB in Series A, Shaking Up the Optical Interconnect Space

On June 3, Guanglian Xinke—a fast-moving startup carving its niche in the optical interconnect (OIO) space—announced it has officially wrapped up a Series A round pulling in nearly 500 million RMB. To put that in perspective, this deal doesn’t just break records for startup valuations in the sector; it completely resets the cumulative funding benchmark. So, who’s backing the vision? A fresh lineup of heavyweights stepped up to co-lead, including Gaorong Capital, Lenovo Capital, and Keytone Capital. They’re joined by top-tier industry funds like GLP Inshan Capital, Ren’ai Capital, and Xinhe Capital, plus hands-on backing from entrepreneurs like Pei Zhenhua. But here’s the real kicker: the company’s original investors didn’t just sit back. Heavy hitters like Legend Capital, Sequoia China, Hillhouse Ventures, Zhenzhi Capital, and Shangshi Capital all doubled down with oversubscribed follow-on investments. It’s a pretty clear message from the market: the smart money is placing its bets on Guanglian Xinke to drive the next wave of optical interconnect innovation.
