Tracking the Hong Kong stock market concept | Fiber optic giants sign another multi-billion dollar deal, domestic fiber optic cable manufacturers systematically venture abroad (with concept stocks attached)

On June 8th local time, Amazon announced a multi-billion dollar agreement with glass and fiber optic technology manufacturer Corning, aimed at supplying fiber optics, cables, and connectivity solutions to support Amazon's expanding data center infrastructure across the United States. In May, Corning signed a major contract with AI leader Nvidia. Corning will establish three new factories in North Carolina and Texas specifically for providing optical products to AI computing leaders. The two companies stated at that time that Corning will increase its domestic optical connectivity product manufacturing capacity by tenfold and expand its U.S. fiber optic capacity by over 50%. The agreement will add 1,000 high-skilled positions and hundreds of construction jobs to Corning's North Carolina factory. This move builds on Amazon's announcement last year of an additional $10 billion investment in cloud infrastructure in the state. Fiber optics are being given AI attributes similar to optical modules and PCBs, transitioning from a traditional communication transmission medium to a critical component supporting AI computing networks. This underlying demand drive has supported the current industry prosperity. Guosheng pointed out in a research report that U.S. domestic fiber optic capacity is highly concentrated among a few manufacturers like Corning, and one of the core variables of this cycle is that overseas demand is becoming a core drive. Chinese fiber optic cable manufacturers are beginning to systematically go abroad. Unlike past cycles driven purely by domestic demand relying on "single market + single customer type," the current cycle has seen fiber optic price increases driven by the resonance of global demand from multiple entities. The sustainability and flexibility of prices will be superior to previous cycles. Guosheng believes that the fiber optic industry is undergoing a different prosperity cycle than before. In contrast to traditional cycles dominated by operator procurement, this current cycle sees the long-term growth logic of fiber optic cables continuing to strengthen, leading to a systematic restructuring of the industry's valuation system. On one hand, the acceleration of fiber optic going abroad opens up long-term incremental space, while on the other hand, the high-density interconnection of AI data centers stimulates a surge in demand for specialty fiber optics, shifting fiber optics from bulk standard products to high-value custom products, significantly increasing unit value. Downstream, MPO and Shuffle Box, as key passive devices for high-density fiber optic interconnection in the AI era, are expected to experience a simultaneous increase in volume and price.
