en.Wedoany.com Report on Mar 21st, U.S. technology companies Ciena and Meta recently announced a new record: successfully transmitting an 800 Gb/s signal over a distance of 16,608 kilometers on a trans-Pacific submarine cable. This achievement marks a significant breakthrough in the transmission distance for single-carrier 800G wavelengths. The test was conducted on the Bifrost cable system, which connects Singapore, Indonesia, the Philippines, Guam, and the U.S. West Coast, and is used for high-capacity data transmission.
The trial utilized Ciena's WaveLogic 6 Extreme coherent optical technology. The signal did not require intermediate regeneration throughout the entire transmission, demonstrating efficient long-distance communication capabilities. In addition to single-wavelength performance, the trial also achieved a total capacity of 18 Tb/s per fiber pair. The system operated with additional headroom, ensuring stable performance in real-world deployments.
Brian Lavallée, Senior Director of Market and Competitive Intelligence at Ciena, stated: "These performance milestones are more than just technical achievements—they reflect the evolving network demands driven by AI and cloud-scale innovation. This means managing a high-capacity, ultra-low-latency, continental-scale private network to better train and deploy AI models and related services. This technology firmly positions organizations like Meta to manage AI-ready infrastructure over vast distances." He also noted that the trial results offer significant advantages in terms of space and energy efficiency, which are critical for submarine landing stations, where every rack unit and every watt of power consumption impacts overall efficiency.
With the rapid development of emerging technologies such as AI and cloud services, global internet and digital capacity demands continue to grow. Advancements in this submarine cable transmission technology will help support the global network of nearly 600 submarine cables, providing more reliable solutions for long-distance data transmission and enhancing data communication capabilities across the Pacific region.
