Investing in 800G Devices to Deploy High-Speed AI Interconnectivity!

  • August 27. 2026

The rapid upgrade of AI computing power and the significant increase in network transmission bandwidth and latency requirements for large-scale model training have rendered traditional 400G networks, which are now limited in performance and unable to meet the demands of high-end intelligent computing scenarios, a new iteration cycle has begun.The industry is now entering a phase of large-scale commercialization of 800G and forward-looking deployment of 1.6T networks, with the industry chain accelerating its upgrades and positioning, and the high-speed interconnection sector poised for high-growth dividends.



Keeping pace with industry iterations, ETU-LINK has introduced a new 800G Optical Module Testing Device. This device has significant advantages, including significantly improving the computational efficiency and cluster scalability of large-scale distributed training, high-throughput inference, and high-performance HPC simulation. It can also serve as a medium- to long-term infrastructure to meet the needs of multi-year computing power expansion, reducing network iteration and transformation costs. The device is highly versatile and forward-looking.


In terms of compatibility, the equipment is fully compatible with mainstream OSFP packaging and can be matched with optical modules such as 800G SR8 and 800G DR8. It is also compatible with the full range of 400G products, which can meet the R&D and testing needs of cutting-edge 1.6T products, taking into account both current mass production and future technology iteration.


Introduction of 800G testing equipment by ETU-Link Technology Co., Ltd. marks a comprehensive upgrade in the company's R&D system, product quality, and technology reserves in the field of high-speed optical communication. Relying on its comprehensive testing and support capabilities, the company will continue to deliver high-performance, high-stability high-speed optical interconnect products, firmly securing its position in the golden track of high-speed optical communication.


Choosing ETU-LINK means not only receiving high-quality products with meticulous attention to detail, but also comprehensive, efficient, and attentive support services to safeguard your communication solutions.
