Juniper QFX5120-48Y-D-AFO2 48-port 25GbE Switch | Data Center, Layer 3

Sustain latency-sensitive workloads with the Juniper QFX5120-48Y-D-AFO2, a compact switch designed for modern data center fabrics where port density, predictable airflow, and high-speed uplinks matter. Its 48 x 25GbE access ports support server aggregation at scale, while 100GbE uplinks provide the bandwidth needed to keep oversubscribed east-west traffic under control. This model fits cleanly into leaf-spine architectures and other high-throughput environments that need consistent forwarding performance without consuming excess rack space. DC airflow out supports front-to-back cooling strategies common in enterprise rows, helping align with established thermal design standards. For teams standardizing on Juniper switching, the QFX5120 family offers the density and fabric readiness expected in production data centers. Choose this switch when you need more than basic connectivity: you need a platform sized for dense virtualization clusters, storage-heavy segments, and growth without immediate forklift replacement. It is built to justify its place in the rack through port economics, uplink headroom, and operational fit.
