A high-tech enterprise specializing in the research and development of optical fiber communications and manufacturing.
Entering 2026, the core challenge for the data center industry is no longer simple capacity expansion. Instead, the industry focuses on efficiently utilizing every kilowatt of power and computing resource to address rapid business growth, rising investment costs, and increasingly complex infrastructure operations, laying a solid foundation for building high-efficiency and intelligent next-generation data centers.
AI advancement has become the core engine driving data center infrastructure upgrading. The rapid adoption of Generative AI and Large Language Models (LLMs) requires supercomputing-level processing capabilities to train sophisticated models and analyze massive datasets. This can only be achieved by distributing workloads across massive interconnected GPU server clusters.
Modern GPU chips consume 700W to 1200W each, and a single high-density AI server can exceed 8 kW in power consumption. With 10 GPUs deployed in one rack alone, power consumption easily hits 80 kW, bringing higher requirements for data center power supply, cooling, cabling and network transmission systems.
The scale of AI training clusters is expanding at an extraordinary speed, evolving from early 10,000 GPU-level clusters to hundreds of thousands or even millions of GPU deployments. Oracle plans to launch an initial deployment of 50,000 GPUs for AI services starting in 2026, while leading industry giants aim for up to 50 million GPUs within the next five years, further boosting the demand for high-density cabling and high-speed interconnection.
Driven by high-speed interconnection requirements, network speeds across all data center layers are undergoing comprehensive iteration. Backend GPU-to-GPU connections are migrating from 800G to 1.6T, while inter-cluster links are evolving toward 3.2T. Frontend switch-to-switch connections are upgrading from 400G/800G to 1.6T, and server access links are moving from 100G/200G toward 400G, fully supporting AI model training, real-time data analysis and cloud application operation.
To accommodate these ultra-high-speed upgrades, high-bandwidth Direct Attach Copper (DAC) and Active Optical Cables (AOC) have become mainstream solutions for direct GPU connections. Cost-effective low-loss multi-fiber parallel single-mode optical solutions are widely adopted for structured cabling between switches and servers.
Currently, the industry widely adopts 100 Gb/s lane rates to support 400G over 8 fibers and 800G over 16 fibers. With the upcoming IEEE 802.3dj standard expected to be released in mid-2026, 200 Gb/s lane rates will enable 800G over 8 fibers and 1.6T over 16 fibers. Looking ahead, 400 Gb/s lane rate technology is already under development, which will support 1.6T over 8 fibers and 3.2T over 16 fibers, further empowering future high-speed data center transmission architecture.
