Juniper QFX5110-48S-AFO 48-Port 10GbE Switch

Equipment Overview

The Juniper QFX5110-48S-AFO is a managed data center access switch from the QFX5110 series, engineered for top-of-rack deployment in enterprise environments. This 1U device provides high-density 10GbE server connectivity with integrated 40/100GbE uplink capability, delivering a total switching capacity of 1.76 Tbps (1.32 Bpps). The unit operates under Junos OS and features AC power with AFO airflow for cold-aisle installation. Its primary tasks include server access, traffic aggregation, and integration into leaf-spine data center architectures.

Main Parameters

• Ports: 48× SFP+ 10GbE, 4× QSFP28 (40/100GbE)
• Switching Capacity: 1.76 Tbps / 1.32 Bpps
• Breakout Support: QSFP28 to 4×10GbE
• Form Factor: 1U rack-mountable
• Power Supply: AC, airflow AFO (rear-to-front)
• Operating System: Junos OS

Key Advantages

This model is selected for enterprise projects requiring high port density in a compact footprint, allowing 10GbE server connectivity without oversubscription. The 100GbE uplinks provide future-proof scaling for growing data center traffic, while breakout capability increases flexible port utilization. The AFO airflow design is optimized for deployment in cold-aisle containment, improving thermal efficiency in modern data halls.

Compatibility & Integration

The switch is compatible with standard SFP+ and QSFP28 optical transceivers and breakout cables, supporting mixed 10/40/100GbE topologies. It integrates with existing Juniper Junos-based management frameworks and is suited for leaf-spine network designs, providing seamless interoperability with data center infrastructure components.
