Popular models include the QFX5100 and QFX5110, widely deployed for 10/40GbE and 10/25/100GbE access and aggregation, along with the QFX5120, which adds dense 25GbE server access and 100GbE uplinks. The QFX5200 and QFX5210 deliver high-density 25/100GbE switching, while the QFX5220 and QFX5130 extend the family into next-generation 100/400GbE fabrics, ideal for cloud-scale deployments.

For larger aggregation and core roles, the QFX10002 fixed systems provide dense 100GbE options in compact form factors, while the QFX10008 and QFX10016 modular chassis scale to thousands of ports with redundant fabric modules, line cards, and power systems for carrier-grade resiliency. All QFX platforms run on Junos OS and support EVPN-VXLAN, MPLS, Segment Routing, automation frameworks, and real-time telemetry.
