Furthermore, Huagong Tech, Guanghe Technology, and Zhongji Innolight are all part of the co-packaged optical (CPO) concept stocks, with institutional visits in the same period being 176, 152, and 119 respectively. In terms of news, according to media reports, NVIDIA is expected to launch new CPO switch products at the GTC conference in March 2025. The supply chain has revealed that this CPO switch is currently in the trial production stage, and if everything goes smoothly, mass production could be achieved by August of this year.
On January 15, Huagong Tech, a well-known high-tech company in the laser industry, announced in its investor relations management information that the domestic market for data communication optical modules will see significant growth this year. Among major internet and equipment manufacturers, the company’s data communication products will cover the full range from 100G, 200G to 400G, and 800G. This year, the delivery of high-rate optical modules will further increase, and the 800G products will continue to ramp up.
In the overseas market for optical connectivity, the company has conducted tests for 400G, 800G, and 1.6T products with several major customers. The 800G LPO products have already seen definite demand, and testing is being expedited for prompt introduction, while the 1.6T products are accelerating sample testing, with overall progress at the top tier of the industry. The company’s overseas factory for optical connectivity business has met production conditions and is preparing for the ramp-up of 800G LPO products in the first quarter.
Guanghe Technology, the largest domestic server PCB supplier, on January 17 released an earnings forecast, estimating a net income of 0.63 billion to -0.69 billion yuan in 2024, an increase of 51.92% to 66.39% year-on-year. The company stated that due to the continuous optimization of the product structure brought by the iterative upgrade of general servers, and the deepening evolution and application of AI, it is anticipated that both the revenue and net income for 2024 will see growth compared to the same period last year. On January 9, Guanghe Technology stated on the interactive platform that the company is developing and producing samples of 800G optical module PCB products for clients, with no mass production orders yet. The company continues to monitor the development trends of cutting-edge technologies and produce products that meet market and customer needs.
Guanghe Technology stated in the investor relations activity record released on December 24, 2024, that HDI uses high-density interconnection and micro blind buried hole technology, which is increasingly applied in the new generation of AI servers. The company is actively planning and laying out high-end HDI production capacity to enhance process capabilities and meet downstream customer demands. Currently, the company's HDI production capacity is small, mainly to meet the needs of downstream customers for data center products. The ongoing technology upgrades will increase the production capacity of these products.
Zhongji Innolight, a global leading optical module solution provider, stated in a conference call on January 10, in response to the question "Have there been rumors that overseas customers have cut orders by 30%?", that the company has not received any order-cutting notifications from clients. On the contrary, there is strong demand for 800G from customers in 2025, with robust order growth. CSP customers are building Ethernet data centers and will purchase 800G in large quantities. The company has absolute advantages in delivery capacity, production capacity, and 800G market introduction progress.
Since last year, the company's 400G silicon photonics has begun volume production, with good delivery and yield rates. The 800G silicon photonics will also start volume production in 2025, while 400G silicon photonics will continue to ship. The progress and demand for 800G have not been affected, and 1.6T will also begin to ramp up seasonally this year. Additionally, 3.2T is currently in the preliminary research stage, with key customers hoping to continue using pluggable technology, while the silicon photonics solution is progressing simultaneously. It is expected that 2026-2027 will be the ramp-up phase for 1.6T, and only thereafter will it gradually move to 3.2T, during which customers' choices and usage of technological paths will be observed.
