Juniper QFX5200-48Y-DC-AFO 48x25G + 6x100G Switch

Usage Area

The Juniper QFX5200-48Y-DC-AFO is a 1U top-of-rack switch deployed in high-performance data centers to provide 25GbE server access and 100GbE uplink aggregation. It is suitable for building scalable leaf-spine fabrics with EVPN-VXLAN technology, enabling efficient traffic segmentation and workload mobility. The model supports dense server connectivity in cold-aisle containment environments, where its front-to-back airflow is optimized. It also serves as a high-throughput aggregation point in enterprise and cloud-scale networks.
