The demand for 100-400G network interfaces continues to grow rapidly, driven by network virtualization and the shift to cloud services. Within data centers, servers now support 10GE or 25GE interfaces, requiring significant bandwidth through top-of-rack switches and between racks. Many large and hyper-scale data centers already have 100G connections between racks, and operators are already migrating to 400G and looking at 800G. These developments are also putting strain on data center interconnects (DCI) between data centers, requiring operators to migrate from 100G to 200G and 400G connections.
This report analyzes the current and projected use of 100G, 400G, 800G and other interfaces by telecom and networking equipment manufacturers, based on the results of an exclusive worldwide survey of engineers, designers, product managers and sales/marketing personnel that work for those suppliers. The responses to our survey make it clear that these devices are critical components in most types of networking equipment, from the access edge to the core of the network and data centers.
