Juniper QFX5130-48CM-D-AFI 48x100G + 8x400G | Data Center, MACsec

Scale a modern data center fabric with a switch built for high-density 100G and 400G connectivity. The QFX5130-48CM-D-AFI combines 48 100G ports with 8 400G ports in a 1U form factor, giving network teams a strong fit for leaf-spine architectures, aggregation layers, and high-throughput interconnects. This port mix matters when the network is no longer constrained by access speed alone. The 100G ports support dense server, storage, and appliance connectivity, while the 400G ports provide the bandwidth needed for upstream fabric links and growth without forcing an immediate platform change. MACsec support adds a security layer for traffic that must stay protected across the switching fabric. For teams standardizing on Juniper in the data center, this model is positioned for serious throughput and long service life. It is the kind of switch selected when rack space is expensive, cabling must stay disciplined, and the network design needs room to expand without compromising speed or security.
