Juniper SRX5K-MPC3-40G10G 6x40GE 24x10GE Module | Enterprise Routing

Built for dense optical networking, the SRX5K-MPC3-40G10G expansion module adds substantial port capacity to Juniper SRX5400, SRX5600, and SRX5800 platforms. With 6 x 40GE ports and 24 x 10GE ports, it gives network teams a practical way to scale bandwidth and port count inside an existing chassis. This module supports both QSFP and SFP+ expansion slot types, aligning with mixed-speed designs where 40 Gigabit Ethernet and 10 Gigabit Ethernet must coexist. That flexibility matters in service-provider edge, enterprise aggregation, and high-throughput data networking environments where port economics and chassis efficiency are closely tied to operational cost. At approximately 20.99 lb, it is a substantial hardware component designed for serious infrastructure deployments, not light-duty branch use. For organizations standardizing on Juniper, it helps preserve the value of installed SRX gateways while delivering the port density needed for growth, migration, and traffic consolidation.
