Data Center Interconnect

Open terascale transport for cloud applications

Data traffic demand is booming, putting enormous pressure on your data center interconnect (DCI) network. You need a scalable solution that can rapidly address this problem while optimizing space and power consumption.

Times have changed. Your main priority is no longer longevity of equipment, with a focus on how many decades it can be milked for revenue. With ever-decreasing life cycles, today’s biggest challenges are technology obsolescence and how to accommodate new technology quickly and efficiently. Sustainability is key. The emphasis is now on minimizing power consumption, footprint and environmental impact; finding the best balance between compactness, integration and modularity to achieve the maximum energy efficiency and minimum material intake. Our FSP 3000 CloudConnect™ is an all-new solution that has been built directly with the industry to address your changing requirements with best-in-class sustainability performance.
