The Juniper QFX5120-48T-AFO is a high-performance, low-latency data center switch designed for enterprise, cloud, and spine-leaf network architectures. It is part of the Juniper QFX5120 Series and is optimized for high-density 10G access with powerful 100G uplink capabilities.
This switch features 48x 10GBASE-T (RJ-45) ports for server and access-layer connectivity, along with 6x QSFP28 uplink ports supporting 40G and 100G Ethernet, enabling flexible and scalable high-speed networking.
Built in a compact 1U fixed form factor, the QFX5120-48T-AFO delivers up to 2.16 Tbps switching capacity, ensuring wire-speed performance across all ports for demanding workloads.
It runs on Juniper Junos OS, providing advanced Layer 2 and Layer 3 features such as EVPN, VXLAN, MPLS, and BGP, along with automation and telemetry capabilities for modern data center operations.
The AFO (Airflow Out) design ensures front-to-back airflow, making it suitable for hot/cold aisle data center deployments. It also includes redundant power supplies and hot-swappable fan modules for high availability and continuous operation.
This switch is ideal for Top-of-Rack (ToR), aggregation layers, and enterprise data centers, where high port density, low latency, and scalable performance are critical.
