The Juniper QFX5120-32C-AFO is a high-performance, low-latency data center switch designed for spine-leaf architectures, cloud environments, and high-density 100G deployments. It belongs to the Juniper QFX5120 Series and is optimized for scalable, high-speed networking with advanced automation capabilities.
This switch features 32x QSFP28 ports, each supporting 100G Ethernet, and can also operate at 40G or break out into 4x25G connections per port, offering exceptional flexibility for modern data center connectivity. It also includes 2x 10G SFP+ ports for management or additional connectivity.
Built in a compact 1U fixed form factor, the QFX5120-32C-AFO delivers up to 6.4 Tbps bidirectional switching capacity with ultra-low latency of around ~550 nanoseconds, ensuring high throughput and efficient traffic handling for demanding workloads.
The switch runs on Junos OS, providing advanced Layer 2 and Layer 3 features such as EVPN, VXLAN, MPLS, and BGP, along with automation and telemetry capabilities. It is designed with front-to-back airflow (AFO), dual redundant power supplies, and hot-swappable fans for reliable operation in data center racks.
It is widely used in spine/leaf topologies, high-speed aggregation layers, and cloud-scale data centers, where high bandwidth, low latency, and scalability are critical.
