Global expansion is a key highlight of the company's fundamentals. In recent years, Suzhou Tfc Optical Communication Co.,Ltd. has established an industrial layout featuring dual headquarters, dual production bases, and multiple R&D centers. Its overseas sales soared from 689 million yuan in 2022 to 3.839 billion yuan in 2025, representing 74.35% of total revenue, indicating deep integration into the global AI computing power supply chain. As a leader in passive optical components, the company has become a core supplier to major global computing power manufacturers like NVIDIA, serving as the exclusive supplier of NVIDIA's CPO optical engines, which demonstrates strong customer loyalty.
Technologically, Suzhou Tfc Optical Communication Co.,Ltd. possesses profound expertise, being the first company globally to deliver 800G and 1.6T optical engines. Data shows that from 2023 to 2025, its cumulative R&D investment reached 642 million yuan, with R&D expenses maintaining double-digit growth rates. In 2025, its 1.6T optical engine entered mass production, successfully passing validation by key global customers like NVIDIA and moving into the volume delivery phase. From an industry trend perspective, 800G optical interconnection products currently represent the most commercially mature solution, with a projected compound annual growth rate of 26.7% from 2025 to 2028, reaching a market size of $16.2 billion by 2028, making it a mainstream solution in the data communication market. Concurrently, as the 1.6T supply chain matures and CPO gradually moves towards mass production, ultra-high-speed transmission solutions represented by 1.6T, 3.2T, and higher rates are expected to see explosive demand, progressively replacing mid-to-low speed rate products.
CPO (co-packaged optics) integrates the optical engine and electrical chip directly onto the same substrate, reducing signal transmission distance from meters to millimeters. Compared to traditional pluggable optical modules, this approach significantly increases bandwidth density, reduces power consumption, and minimizes transmission latency, effectively addressing the thermal and power bottlenecks faced by AI computing clusters in high-throughput, high-density operating scenarios. It is the only viable path to support 800G, 1.6T, and higher rates. As AI model parameters approach the trillion-scale, traditional 800G technology is reaching its physical performance limits, making CPO an essential technology for AI computing clusters, supercomputing centers, and high-end data centers. Public information indicates that both NVIDIA and Broadcom plan to launch CPO switches and related GPU/XPU products in 2026, suggesting a faster commercialization timeline than market expectations. Facing this next-generation core technology in optical communications, Suzhou Tfc Optical Communication Co.,Ltd. has successfully become a core partner for CPO solutions with leading global AI computing infrastructure manufacturers and has begun laying the groundwork for next-generation technological pathways like silicon photonics integration and thin-film lithium niobate.
Its strategic positioning in the high-value upstream segment of the chain, deep integration with leading customers like NVIDIA, and generational leadership in both current and next-generation technologies collectively form a strong foundation for its fundamentals and long-term prospects.
Despite the high-growth industry cycle, the sector leader still faces multiple challenges. Optical communication, with advantages like large bandwidth, low loss, low cost, and high fidelity, has become the mainstream transmission technology for core applications such as data centers, telecom backbone networks, and fiber-optic broadband. Driven by the global AI computing power construction boom, data centers, as fundamental infrastructure, are accelerating upgrades. On one hand, optical communication acts as a "super artery" for data transmission, with continuously rising market demand; on the other hand, as AI computing power rapidly expands from core training to large-scale inference, the volume of data exchange within data centers grows exponentially, imposing higher requirements on the bandwidth, speed, and stability of optical communication technologies.
According to Frost & Sullivan data, the global optical component market reached approximately $6.1 billion in 2025, with a compound annual growth rate of 15.4% from 2021 to 2025, indicating the industry is in a high-growth upcycle. The top five suppliers collectively hold 25.4% of the market share, with Suzhou Tfc Optical Communication Co.,Ltd. ranking first globally with an 11.7% share. However, even within this favorable cycle, the company confronts several risks and uncertainties.
Firstly, persistent tight supply of optical chips may lead to continuously rising raw material costs. Data shows that the proportion of raw material costs to total sales cost increased during the reporting period, rising from 607 million yuan (67.2%) in 2023 to 1.777 billion yuan (73.8%) in 2025, an increase of 6.6 percentage points. This is mainly due to continuous price increases and supply shortages of global high-end optical chips, such as EML chips. EML is currently the mainstream core solution capable of covering 1.6T and 3.2T requirements. Market information indicates that the indium phosphide wafer fab of Lumentum, a leading global optical chip maker, is operating at full capacity, with production sold out for the next six quarters. The supply-demand gap for EML optical chips is estimated at 25% to 30%, and the company plans to implement further price hikes in 2026. Additionally, market forecasts suggest prices for 100G EML chips could rise 15% to 20% in 2026, while 200G continuous wave light sources might see increases up to 30%. Domestically, there are even instances of customers offering 10% to 15% premiums to secure early deliveries, indicating that the chip price inflation trend driven by supply-demand tightness may persist into 2026. If upstream chip supply constraints are not alleviated, Suzhou Tfc Optical Communication Co.,Ltd.'s production delivery capacity and gross margin levels could face pressure.
Secondly, although CPO is widely recognized as the core technological direction for next-generation optical communication, its full commercialization will take time. Although NVIDIA confirmed at its GTC conference that its Feynman architecture will adopt CPO, volume production is not expected until around 2027, implying a transition period of approximately one to two years. Currently, large-scale CPO production capacity across the supply chain is not yet fully established, and the business model for CPO switches is not finalized. Until CPO achieves mass commercial deployment, the actual benefits for Suzhou Tfc Optical Communication Co.,Ltd. as an upstream supplier remain uncertain. Several industry analysts note that, in the short to medium term, the key to the company's earnings growth still hinges on its capacity to deliver 1.6T optical engine products. While its Phase 2 production capacity in Thailand is now operational, the pace of the production ramp-up remains uncertain.
Thirdly, Suzhou Tfc Optical Communication Co.,Ltd.'s overseas sales now exceed 70% of its revenue, and it is deeply integrated into the US AI supply chain. Against the backdrop of intensifying global technology competition, any policy changes related to supply chain decoupling, tariffs, or export controls could significantly impact its performance. Furthermore, fluctuations in the Renminbi exchange rate directly affect its foreign exchange gains and losses.
In summary, Suzhou Tfc Optical Communication Co.,Ltd. is positioned at a historic opportunity presented by the AI computing power wave. Leveraging its technological leadership and deep ties with leading customers like NVIDIA, it has secured a strong position in the global optical components market. However, short-term factors such as the production ramp-up pace, upstream chip supply bottlenecks, and the time lag between CPO technology introduction and mass commercialization remain potential variables requiring close market monitoring. For investors, beneath the光环 of the AI boom, a冷静 assessment of the company's potential risks remains essential.
