Inside the production workshop, equipment hums softly as workers in cleanroom suits keep their eyes fixed on the process parameters flickering on screens, methodically carrying out each procedure.

"This production line covers chip mounting and eutectic bonding, wire bonding, coupling alignment, product testing and other production processes," Wu Yuming, manufacturing department director of Suntel Communications, told reporters while standing beside the line. "The new Yaohu factory has laid out 20 high-speed optical module production lines in total, and the company is striving to achieve full-load production in the fourth quarter of this year. At full capacity, monthly output of high-speed optical modules can reach 700,000 units, more than tripling that of the original plant. At present, 1.6T optical modules have already achieved mass production."

High-speed optical modules are not only the cornerstone of long-distance communication in carrier networks, but also the core of high-speed interconnection between servers within data centers, undertaking the key function of transmitting and receiving, and converting, optical and electrical signals. "At present, our technology is among the domestic leaders, with core advantages mainly reflected in highly automated production lines and an AI-enabled intelligent workshop control system, forming differentiated competitiveness in process error-proofing and production mistake-proofing," Wu Yuming said, pointing to the precision equipment on the line. The plant is equipped with industry-leading production equipment, including three-micron-level high-precision imported die bonders and coupling equipment supplied by top domestic manufacturers, safeguarding product yield and consistency from the hardware level.

Inside the workshop, a technician bends over to fine-tune packaging parameters as micron-level precision indicators flicker on the screen. "The higher the rate of a high-speed optical module, the faster and more stable the data transmission. 1.6T is at the industry's forefront today, with process precision requirements reaching the micron level—the slightest deviation can affect signal quality," the technician told reporters while operating the equipment. It is precisely this extreme refinement of every process that sends each "Nanchang-made" optical module to the global computing power market.

"After the Nanchang Phase III new factory was put into use, our high-speed optical module production capacity has been comprehensively upgraded, laying a solid manufacturing foundation for undertaking larger-scale computing power orders," said Du Guangyun, general manager of Suntel Communications. The company started in Qingshanhu, transformed in Aixihu, and has now laid out a larger base in Yaohu, and it has always been optimistic about Nanchang's sound electronic information industrial foundation, continuously optimized policy supply and local talent support.

"Expanding production here can both improve the efficiency of local supply chain supporting facilities and drive the clustered development of upstream and downstream optoelectronic component enterprises," said Du Guangyun, who has witnessed the rapid changes in Nanchang High-tech Zone. He recalled that when the company settled in Nanchang High-tech Zone in 2017, the area's urban appearance and industrial supporting facilities were incomparable to what they are today; the company itself has also continued to expand capacity, from one factory building to three, and now to this modern new base in Yaohu—every step of growth has been inseparable from local support. "The construction cycle of the new project was greatly shortened, with the government coordinating on the front line throughout. Policies benefiting enterprises, such as rent reductions and exemptions, have truly reduced burdens and empowered the company."

Talent shortages were once a challenge faced in the company's early development. After more than a decade of deep cultivation, the situation has quietly reversed. "We have continuously engaged with local universities in Nanchang, carrying out campus recruitment and independent training. Now many R&D heads and engineering backbones are graduates of local universities and have become the mainstay of our technological iteration," Du Guangyun said.

As a key AI high-speed optical module construction project in Nanchang High-tech Zone, the base focuses on the core demand for high-speed interconnection in AI intelligent computing centers, specializing in the large-scale packaging and production of 800G, 1.6T and other high-speed optical modules. Its products are widely used in core scenarios such as AI intelligent computing centers, ultra-high-speed Ethernet and large data centers, which will provide solid support for the company's sprint toward the goal of 10 billion yuan in output value and inject new momentum into Nanchang High-tech Zone's efforts to consolidate the industrial foundation of AI computing power hardware manufacturing.

Looking to the future, Suntel Communications' layout goes beyond current capacity. "The Phase III manufacturing base put into operation this time has a first-phase building area of more than 20,000 square meters, with 30,000 square meters of development space reserved for the second phase, mainly for subsequent capacity expansion and the introduction of new products. Next, we will continue to expand 800G and 1.6T high-speed optical module production lines according to market demand, while advancing productization research on next-generation cutting-edge optical module technologies such as NPO/3.2T," Du Guangyun introduced.

As a national high-tech enterprise and provincial specialized, refined, distinctive and innovative enterprise rooted in Nanchang High-tech Zone, Suntel Communications' growth trajectory resonates with the industrial development of Nanchang High-tech Zone. From its founding in 2012, to completing its transformation from a trader to an integrated entity enterprise of R&D, production and sales in 2017, and now to the commissioning of the Phase III base on the shores of Yaohu, the company took only three years to achieve a strategic turn from the telecom market to the data communications market. It has now formed a full-rate product matrix from 10G to 1.6T and is a main supplier in China's optical communications field. As the Phase III factory's capacity continues to be released, more and more "Nanchang optical chips" will be embedded in the global AI computing power network, injecting a steady stream of new momentum into Nanchang's efforts to build a highland for the optoelectronic information industry in central China.
