Juniper QFX5100-48S-AFO 10GbE Switch for Data Centers

Equipment Overview

The Juniper QFX5100-48S-AFO is a managed switch from the QFX5100 series, engineered for access and aggregation layers in enterprise data center networks. It provides high-density 10GbE connectivity with uplink flexibility, supporting server aggregation, storage connectivity, and compute cluster interconnects. The device operates under Junos OS and is suited for leaf-spine topologies requiring low-latency, high-throughput switching.

Main Parameters

• Ports: 48x SFP/SFP+ 10GbE, 6x QSFP+ 40GbE
• Switching capacity: 1.44 Tbps (1.08 Bpps)
• Breakout support: 40G to 4x10GbE
• Form factor: 1U
• Power supply: AC, airflow AFO (rear-to-front)
• Operating system: Junos OS

Key Advantages

This model is selected for enterprise projects due to its high port density and flexible 40GbE uplinks, enabling cost-effective scaling of 10GbE server farms. The AFO airflow design optimizes cooling in cold-aisle containment, while Junos OS ensures consistent configuration and management across the network. Breakout capability increases 10GbE port count without additional hardware, reducing deployment complexity.

Compatibility & Integration

The switch supports SFP+ and QSFP+ optical modules and breakout cables, ensuring interoperability with standard 10GbE and 40GbE infrastructure. It integrates into Juniper-based data center fabrics and adheres to open networking standards for multi-vendor environments. The unit fits standard 19-inch racks and is compatible with Junos OS feature sets for leaf-spine deployments.
