Listed Companies in Integrated Optics Sector Embrace Development Opportunities

Securities Daily Reporter Wang Jingru

Against the backdrop of continuous explosive growth in AI computing power demand, the Co-packaged Optical (CPO) sector has once again become a focus of market attention.

As of the close on March 18, many stocks in the CPO sector performed actively. Riscon Technology Development Co., Ltd. hit the daily limit, while Suzhou Tainfu Optical Communications Co., Ltd. and Wuhan Guangxun Technology Co., Ltd. (hereinafter referred to as “Guangxun Technology”) saw significant gains.

Dr. Zhang Xiaorong, Director of the Deep Technology Research Institute, told Securities Daily: “With the rapid development of generative AI and large models, the internal communication pressure within data centers continues to rise. Traditional copper interconnects are gradually approaching physical limits in bandwidth and power consumption, becoming a major bottleneck for AI computing power expansion. CPO technology, by integrating optical engines with switching processors in a single package, enables optical signals to transmit over shorter paths, significantly reducing power consumption and transmission loss.”

In this context, domestic listed companies are accelerating their deployment of CPO and related optical communication technologies, with some companies already delivering results. For example, benefiting from sustained growth in computing power investments, the demand for high-speed optical modules has increased significantly. Chengdu New Easy Sheng Communication Technology Co., Ltd. is expected to achieve a net profit of 9.4 billion to 9.9 billion yuan in 2025, representing an estimated year-on-year growth of 231.24% to 248.86%.

Meanwhile, technological iteration within the industry is accelerating. Guangxun Technology recently announced that its 3.2T silicon photonic single-mode NPO module has completed sample testing. The sample includes a complete NPO system solution, covering optical engine OE, external light source module ELSFP, and fiber management module FMU-Shuffle, with full capabilities for system-level integration verification. Shenzhen Zhaochi Co., Ltd. announced in March that its 1.6T optical module has entered rapid development, focusing on multiple pathways such as LPO, NPO, and CPO to layout next-generation high-speed, low-power solutions simultaneously.

Wuxi DeKeli Optoelectronic Technology Co., Ltd. continues to expand into overseas markets and plans to relist in Singapore. A company executive stated that this listing is a key move in the company’s internationalization strategy, aiming to broaden global financing channels through mature market platforms, improve capital management capabilities, and enhance its international competitiveness in the optical communications field.

Gao Zhengyang, a special researcher at the Shanghai Commercial Bank, told Securities Daily: “Currently, leading global technology companies driven by AI computing power demand are continuously increasing their demand for high-bandwidth, low-power optical communication solutions, which is driving the growth of the CPO market. Meanwhile, domestic companies, with their mature product mass production capabilities, are gradually landing overseas orders, further confirming the industry’s high prosperity. The dual factors of short-term capital chasing and long-term industry logic together form the core driving force behind the continued strength of this sector.”
