Super node construction cycle opens. Listed companies continue to increase their investment in the silicon photonics track.

On July 22, Zhongji Xuchuang initiated the Hong Kong stock offering, expecting to raise 5.45 billion Hong Kong dollars for research and development of optical interconnection products and global production capacity expansion. On July 15, Shijia Guangzi disclosed a 2.8 billion yuan issuance plan, intending to raise funds for additional optical interconnection component construction projects. Optical interconnection, a technology term that was slightly obscure just one year ago, is becoming one of the most crowded tracks in the computing power industry. Behind the frenzy is the rigid demand brought by the evolution of the AI industry. With AI entering the era of reasoning, the continuous iteration of trillion-parameter large models and the start of the construction cycle of super nodes have raised attention to optical interconnection technology for its high bandwidth, low power consumption, high parallelism, and scalability advantages. Currently, the domestic optical interconnection ecosystem is forming alliances with upstream and downstream manufacturers in the industry chain, and listed companies are continuing to increase their investments in the silicon photonics track.
