Global AI Data Center Optical Fiber (AIDC Fiber) Market Strategic Research Report

Scope of the Report

The global AI Data Center Optical Fiber (AIDC Fiber) market size is predicted to grow from US$ 747 million in 2025 to US$ 4,357 million in 2032; it is expected to grow at a CAGR of 21.8% from 2026 to 2032.

AI Data Center Optical Fiber (AIDC Fiber) refers to optical fiber products designed for internal and cross-data center high-speed interconnects in AI compute clusters, high-performance cloud data centers, and internet data centers. It encompasses multimode and single-mode fibers, bend-insensitive and low-loss fibers, to meet the bandwidth, low latency, low loss, and high-density cabling requirements of 400G, 800G, 1.6T, and higher optical modules. Serving as the “neural network” infrastructure of data centers, AIDC fiber is primarily used for server-to-switch interconnects within racks, rack-to-rack links, and data hall backbone connections, while supporting high-density MPO/MTP and other efficient termination schemes.

Driven by AI and cloud computing, AIDC fibers not only carry large-scale east-west traffic at high speeds but also must maintain excellent bend performance, low insertion loss, and long-term reliability in high-density deployment scenarios. Compared with traditional data center fiber, the increased fiber demand generated by GPU clusters in AI data centers is reshaping the optical fiber market, making high-end data center fibers one of the fastest-growing segments in the optical communications industry. The share of AI data center fiber in the global optical fiber market is projected to rise rapidly from less than 5% in 2024 to approximately 30%–35% by 2027. In 2025, global AI Data Center Optical Fiber (AIDC Fiber) shipments reached approximately 107 million fiber-km, with an average price of about USD 7.14 per fiber-km and a gross margin of around 40%.

The deployment of AI foundation model training clusters, large-scale GPU clusters, and high-performance cloud data centers is accelerating demand for AIDC optical fiber. In high-density rack and data center environments, fibers with bend insensitivity, low loss, and small coating diameters have become essential, driving rapid development of high-end single-mode and multimode fibers.

The industry faces challenges such as constrained production capacity of high-end fibers, long upstream preform and raw material supply cycles, and limited manufacturing and delivery capabilities. High-density MPO/MTP termination and complex cabling solutions also place higher requirements on manufacturer design, quality control, and delivery performance.

AIDC optical fiber is reshaping the growth logic of the optical fiber industry. Compared with traditional cloud data centers, AIDC fiber consumption is higher and deployment density grows exponentially, driving the sector into a super-cycle of rapid growth. Scale-out cluster interconnects and data center interconnects represent the core demand scenarios.

As AI foundation models and large-scale compute clusters are deployed, AIDC optical fiber demand is expected to continue growing rapidly. The industry is moving toward high-density, high-performance, low-loss, bend-insensitive, and hybrid multimode/single-mode solutions to meet the requirements of next-generation AI data center upgrades and cross-data center interconnects.
