The rapid growth of artificial intelligence and large-scale AI data centers is creating a new wave of demand for optical fiber. Unlike previous growth cycles driven mainly by 5G and fiber-to-the-home deployment, today's demand increasingly comes from high-speed optical interconnection inside data centers.

As AI models become larger, thousands of GPUs may need to work together and exchange massive amounts of data. This is driving rapid growth in east-west traffic and increasing the need for high-speed optical connections between GPUs, servers, and switches.

In other words, fiber is gradually moving from “connecting homes” to “connecting computing power.”

Supply Constraints Support Higher Prices

While demand is growing rapidly, fiber supply cannot be expanded at the same speed. Fiber preform manufacturing requires advanced technology, significant investment, and a relatively long capacity expansion cycle. After several years of weaker market conditions, industry capacity expansion has also remained relatively cautious.
The result is a short-term supply-demand imbalance, which has contributed to rising fiber demand and prices. However, as new production capacity comes online over the next few years, supply is expected to gradually improve, and standard fiber products may face renewed price competition.

Chinese Fiber Enters a New Global Growth Phase
China has developed a highly integrated fiber optic manufacturing ecosystem, with strong capabilities in fiber preforms, optical fiber, optical cables, and related components. Advantages in manufacturing scale, cost efficiency, supply chain integration, and delivery capability are helping Chinese manufacturers respond to growing global demand.
As international demand continues to increase, overseas markets are becoming an increasingly important growth area for China's fiber optic industry.

The Next Competition: Technology

In the long term, however, capacity and cost alone will not be enough. As AI infrastructure develops, data centers will demand higher capacity, lower optical loss, lower latency, and greater reliability.

Technologies such as hollow-core fiber, multi-core fiber, and ultra-low-loss fiber are therefore attracting increasing attention.

Overall, AI is not simply increasing fiber consumption—it is changing the structure of fiber demand. As AI computing and data center infrastructure continue to expand, optical communication is entering a new growth cycle, with high performance, advanced technology, and specialized applications becoming increasingly important.
