Ciena and Lightstorm Enhance Subsea Cable Capacity for AI Demand

• •Lightstorm upgraded JGA cable capacity from 100 Gbps to 400 Gbps to support AI and cloud services.
• •Ciena's technology achieved a record 800 Gbps on the Bifrost Cable System, enhancing global connectivity.
• •The upgrades improve efficiency and reduce costs for data transmission between major data centers.

Ciena has upgraded the Japan-Guam-Australia (JGA) submarine cable system, increasing its capacity from 100 Gbps to 400 Gbps using WaveLogic coherent optical technology. This upgrade, in collaboration with Lightstorm, aims to meet the rising demand for cloud computing and AI workloads. The JGA cable connects Tokyo and Sydney via Guam, providing an alternative to routes through the South China Sea. The enhanced capacity supports live commercial traffic, improving fibre-pair efficiency and lowering costs for data-heavy applications. Ciena's technology also achieved a world record of 800 Gbps on the Bifrost Cable System, showcasing the potential for subsea cables to support AI and cloud services. The upgrades are critical as demand for digital capacity continues to grow, driven by AI and emerging technologies. Ciena anticipates further advancements in capacity and efficiency as it collaborates with Meta on these projects.
