High-density 25G and 100G port configuration
This Juniper EX4650-48Y-AFO switch module delivers 48 ports of 25G Ethernet and 8 ports of 100G Ethernet in a single 1U form factor. The port-side intake and exhaust airflow design supports standard data-centre hot-aisle or cold-aisle layouts. It is built for high-throughput environments that need dense, line-rate connectivity without consuming extra rack units.
Advanced security and routing capabilities
The platform includes access control lists and firewall functions to protect traffic flows across the fabric. Layer 2 and Layer 3 feature sets enable flexible segmentation and routing policies for multi-tenant or campus deployments. EVPN-VXLAN support allows overlay architectures that simplify network automation and workload mobility.
Suited for enterprise
Network teams deploying spine-leaf fabrics or collapsing distribution layers will benefit from the combined 25G access and 100G uplink density. Organisations requiring PoE, deeper buffer pools, or modular line-card expansion should evaluate alternative platforms that address those specific requirements.

Questions about this item
What maintenance will the 48x25G SFP28 and 8x100G QSFP28 transceivers require over time?
The SFP28 and QSFP28 transceivers are hot-swappable modules; maintenance consists of periodic cleaning of optical connectors and replacing any module that shows increased error rates or link failures.
Which limit appears first when the 48x25G and 8x100G ports run at sustained line rate?
The port-side intake and exhaust airflow design sets the thermal boundary; if ambient temperature exceeds the rated operating range the switch will throttle or shut down before any port bandwidth limit is reached.
How much noise and heat does the port-side intake and exhaust airflow generate during all-day operation?
The 1U chassis uses internal fans to pull air from the port side and exhaust it the same direction; acoustic output and heat dissipation scale with fan speed, which rises as inlet temperature increases.
