Ciena upgrades subsea cable throughput for Meta, Lightstorm | Computer Weekly
"Ciena and Meta achieved a new world record in unregenerated single-carrier 800 Gb/s across the 16,608 kilometre-long transpacific submarine cable, delivering high-performance connectivity from Singapore to California."
"Ciena's WaveLogic 6 Extreme technology redefines capacity, efficiency, and sustainable global connectivity, providing a 50% reduction in watts/bit compared to previous generations of coherent modems."
Ciena's technology has set a world record of 800 Gbps on a single wavelength across the Bifrost Cable System. This achievement supports the increasing demand for internet and digital capacity driven by AI and cloud services. Ciena and Meta's collaboration on the transpacific submarine cable demonstrates the need for robust submarine infrastructure to handle vast datasets for AI training. The project showcases Ciena's WaveLogic 6 Extreme technology, which offers significant improvements in capacity and efficiency, achieving 18 Tbps total fibre pair capacity with reduced energy consumption.
