Juniper QFX5220 Series Switches (Used & Refurbished)
The Juniper QFX5220 Series delivers ultra-high-performance data center switching designed for modern 100GbE and 400GbE fabrics. Built for hyperscale, cloud, and service provider environments, the QFX5220 family is optimized for spine-and-leaf EVPN-VXLAN architectures, AI/ML workloads, and bandwidth-intensive east-west traffic.
BrightStar Systems supplies fully tested, seller refurbished Juniper QFX5220 switches, backed by our 1-Year In-House Warranty. Available configurations support multiple port densities, airflow orientations, and deployment roles to align with high-density data center designs.
For environments transitioning from earlier 25GbE or 100GbE platforms, the QFX5220 Series is commonly evaluated alongside QFX5130 and QFX5200 switches.
Juniper QFX5220 Series Overview
The QFX5220 family is powered by next-generation Broadcom ASIC technology, delivering massive throughput, deep buffers, and deterministic low latency for large-scale fabrics. These switches are engineered primarily for spine and high-capacity leaf roles in modern Clos architectures.
Key features of the QFX5220 Series include:
High-density 100GbE and 400GbE QSFP-DD interfaces
Up to 25.6 Tbps switching capacity (model dependent)
Optimized for EVPN-VXLAN, SR-MPLS, and SRv6 fabrics
Advanced telemetry with JTI and streaming analytics
MACsec support on select models for secure interconnects
Ultra-low latency switching for AI/ML and HPC workloads
Extensive automation: ZTP, NETCONF/YANG, Python, REST APIs
AFI (front-to-back) and AFO (back-to-front) airflow options
In large data center deployments, QFX5220 switches are frequently paired with QFX5130 leaf switches and QFX10K platforms for core and aggregation layers.
