There are multiple transitions at play in data centers and campus networks. In data centers, enterprise customers are migrating from 1G/10G to 25G networks for server and storage. Core links are being upgraded from 10G/40G to 100G. Many use cases, such as content and media, are driving the need for even higher speeds at 400G. Similarly, in campus networks, customers are moving from 1G to mGig to support new WiFi standards and high bandwidth endpoints.
