Juniper Networks QFX Series Switches empower modern data centers, campus networks, and cloud infrastructures with high-performance, scalable, and reliable switching solutions. Designed for demanding AI, machine learning, and high-throughput applications, these switches deliver ultra-low latency, intent-based automation, and robust programmability. Consequently, businesses achieve seamless connectivity for spine-and-leaf architectures, top-of-rack deployments, campus core, and data center interconnects. With Juniper Apstra integration, QFX switches streamline the network lifecycle—from design to deployment—offering up to 90% faster deployments and 83% OpEx savings through closed-loop assurance.

The QFX portfolio caters to diverse needs. For instance, the QFX5240, powered by Broadcom Tomahawk 5, supports 64x800GbE and flexible breakout up to 256x100GbE, excelling in AI-driven data center fabrics with BGP, MPLS, and RoCEv2 support. Similarly, the QFX5230 offers scalable 400GbE for high-density spine-and-leaf setups, while the QFX5700 delivers enterprise-class 10/25/40/100/200/400GbE for cloud and HPC environments. Meanwhile, the QFX5130 provides cost-effective 25.6 Tbps bidirectional switching for service providers, and the QFX5120 ensures 550ns latency for edge and campus networks with EVPN-VXLAN and Mist AI integration. Additionally, the QFX10000 Series scales up to 96 Tbps, leveraging Juniper’s Q5 ASIC for hyperscale deployments.

Running Junos OS, QFX switches support full-stack routing, including BGP, MPLS, EVPN-VXLAN, and IPv6, alongside ZTP, Python, and Terraform for automation. Combined with Mist AI and Apstra, they enable intelligent, secure, and automated operations for AI-driven and cloud-native networks. Therefore, Juniper QFX Series Switches stand as the ideal choice for businesses seeking agile, high-density Ethernet solutions to meet evolving network demands.
