通信行业周报：AI与无人机驱动光纤新周期

Investment Rating - The report maintains a "Buy" rating for key companies in the optical fiber and cable industry, including Zhongji Xuchuang, Xinyi Sheng, and Tianfu Communication [11]. Core Insights - The optical fiber and cable industry is entering a new cycle driven by AI data centers and drone applications, with fiber prices having more than doubled since 2025, indicating a significant upturn in market conditions [1][20]. - The demand for optical fibers is shifting from traditional telecom needs to AI data centers, which require 5 to 10 times more fiber infrastructure than traditional cloud facilities. The share of AI fiber in global demand is expected to surge from 5% in 2024 to 30% by 2027 [3][25]. - Supply constraints are evident due to the long production cycle of optical fiber preform, which can take 18-24 months to expand capacity, leading to a tight supply-demand balance [4][23]. Summary by Sections Price Dynamics - Since late 2025, retail prices for optical fibers have been on the rise, with G.652.D bare fiber prices exceeding 30 yuan/km, and actual transaction prices often between 40-50 yuan/km, reflecting a cumulative increase of 94%-144% [2][21]. - The rising fiber prices have caused a mismatch with operator bidding limits, leading to the suspension of collective procurement projects by operators like Guangdong Telecom [2][21]. Demand Drivers - The primary demand driver for this cycle is the construction of AI data centers, which significantly increases the demand for optical fibers. The consumption of fiber infrastructure by AI data centers is projected to be 5 to 10 times greater than that of traditional cloud facilities [3][25]. - The drone sector is also emerging as a new demand market, with current fiber demand related to drones estimated at 50 million core kilometers per year, significantly increasing Russia's fiber consumption [3][25]. Supply Constraints - The production of optical fiber is constrained by the lengthy and technically challenging process of expanding optical preform capacity, which directly limits overall supply [4][23]. - The focus on producing specialty fibers for AI data centers has led to a reduction in the production capacity for standard G.652D fibers, creating a supply gap for general fibers [7][24]. Investment Recommendations - The report recommends focusing on companies within the optical communication sector, such as Zhongji Xuchuang and Xinyi Sheng, as well as companies involved in the broader computing power supply chain, including those in liquid cooling and satellite communication [8][14][26].
