High-density 25GbE SFP28 switch

The Juniper Networks QFX5120-48Y-AFI is a rack-mountable Layer 3 switch built for data-centre and enterprise networks. It provides 48 ports of 25 Gigabit Ethernet SFP28 connectivity plus four 100 Gigabit Ethernet QSFP28 uplinks. The platform supports advanced routing protocols such as HCRP and SPP for resilient traffic management.

Deciding specification: 48 x 25GbE SFP28 ports

The port count and speed define whether this switch matches the density and throughput requirements of the target topology. Each SFP28 port delivers 25GBase-X performance, while the four QSFP28 uplinks operate at 100GBase-X for aggregation or spine links. No other port speeds are populated on this model.

Suits teams needing high-density 25G access

Organisations that require a different mix of 10GbE, 40GbE or 100GbE port densities should evaluate alternative configurations. Buyers who need integrated PoE, a different form factor or a specific protocol not listed here will need to look at other platforms.
