The Juniper 611-047152 is a 4-port 10GbE SFP+ uplink module designed for the EX4300 line of enterprise-class switches. This line-card form factor provides four SFP+ ports operating at 10 Gigabit Ethernet speeds, enabling high-throughput uplink connectivity between switch stacks or to core network infrastructure. Compatible exclusively with EX4300 modular chassis, the module supports industry-standard SFP+ optics for flexible deployment over multimode or single-mode fiber. Typical use cases include data center aggregation layers, service provider environments, and campus networks requiring scalable uplink capacity without replacing the base switch platform. The module integrates seamlessly into EX4300 slot architectures for non-disruptive addition of 10GbE port density.
