On the news front, according to the China Electronic Components Industry Association, in January 2026, the average price of G.652.D single-mode optical fibers in the Chinese market exceeded 40 yuan/core kilometer, reaching a new high in nearly seven years, with some manufacturers quoting prices as high as 50 yuan/core kilometer; the single-month market price in January increased by more than 75%. Huayuan Securities pointed out that the core reason for the increase in optical fiber prices is the reversal of supply and demand for optical fibers: the supply side's production capacity is continuously being cleared, while the demand side's construction of AI data centers is accelerating, leading to a situation where various types of optical fibers are in short supply. The firm believes that the prosperity of optical fiber cables is expected to continue to improve as the price of optical fibers rises, and it is optimistic about the performance of related companies.
