Juniper QFX5130-48CM-AFI 48x100G + 8x400G Switch | Data Center

Move more traffic through fewer rack units with the Juniper QFX5130-48CM-AFI. This 1U switch is designed for high-density data center environments where 100G server and aggregation links must coexist with 400G uplinks for fabric growth. The port mix supports modern leaf-spine architectures, giving infrastructure teams a clean path to higher bandwidth without redesigning the rack. With 48 x 100G ports and 8 x 400G ports, this model is suited to environments that need to aggregate large numbers of high-throughput endpoints while preserving headroom for upstream scaling. That matters when you are standardizing on faster interconnects, reducing oversubscription pressure, or preparing for storage, virtualization, and AI-related traffic patterns that punish slower fabrics. The 1U form factor helps preserve valuable rack space, while the AC FRU design supports serviceability in production environments. For teams comparing this class of switch against lower-port-count alternatives, the value is in consolidation: fewer devices, cleaner cabling, and more capacity per rack unit. It is a strong fit when the network design must keep pace with compute density and long-term bandwidth growth.
