Juniper QFX5120-48T-DC-AFI 48x10GbE 6x100G 1U Switch | Data Center

Keep east-west traffic moving with a compact switch designed for modern data center aggregation and leaf-spine deployments. The Juniper QFX5120-48T-DC-AFI combines 48 x 10 GbE access ports with 6 x 100 GbE uplinks, giving infrastructure teams the port mix needed to scale server connectivity without sacrificing uplink headroom. Built in a 1U rack-mountable chassis, this model is suited to environments where every rack unit must justify its footprint. Layer 3 support helps align the switch with routed fabric designs, while the 100 GbE uplink architecture supports higher-bandwidth aggregation paths for storage, virtualization, and clustered application traffic. The DC airflow-in configuration is a practical fit for facilities that standardize front-to-back cooling patterns. That matters when you are matching switch orientation to the rest of the rack and keeping thermal planning consistent across the row. For teams comparing enterprise switching options, this model stands out when you need more than basic access switching. It is built for data center operators who want a dense 10 GbE edge with a clear path to 100 GbE uplinks, without moving to a larger chassis or overbuying capacity they will not use.
