Aqua Comms, a global subsea connectivity services provider, has announced its first live commercial 400 Gbps Ethernet Trans-Atlantic service for Energy Sciences Network (ESnet), a high-performance network that supports scientific research, funded by the U.S. Department of Energy’s Office of Science and managed by the Lawrence Berkeley National Laboratory. ESnet provides services to over 50 Department of Energy research sites, including supercomputing facilities, major scientific instruments, and the entire National Laboratory system.

Aqua Comms’ 400GE circuit replaces the existing 100GE circuit on the New York-London route in ESnet’s network. The upgraded circuit increases the aggregate Trans-Atlantic bandwidth from 400 Gbps to 700 Gbps. The network uses Ciena’s GeoMesh Extreme submarine network solution, powered by WaveLogic 5 Extreme coherent optics and Manage, Control and Plan (MCP) advanced software capabilities, to support ever-growing connectivity and bandwidth needs.

Jon-Paul Herron, ESnet’s Department Head of Network Services, said, “ESnet is actively preparing the network to meet the flood of data coming from all of our upcoming science needs, including the high-luminosity upgrades of CERN’s Large Hadron Collider as well as the related CERN Data Challenge ’24 (DC24) during the first quarter of next year.”

Chris Bayly, Chief Commercial Officer at Aqua Comms, said, “As super computing requirements continue to grow, we envisage 400Gb/s and the transition to spectrum services being more widely consumed by organisations such as ESnet to help accommodate an almost insatiable need for bandwidth.”
