Juniper EX4400-EM-4S 4x10G SFP+ Module

Extend switch capacity with four 10 GbE SFP+ ports designed for Juniper EX4400 environments. The EX4400-EM-4S gives network teams a practical way to increase uplink density for access, aggregation, and campus edge designs without a full platform refresh. This module is built for deployments where port pressure is rising faster than rack space or budget. By adding SFP+ connectivity at 10 Gigabit Ethernet speeds, it helps preserve performance for virtualization traffic, storage access, and east-west application flows while keeping the switching layer consistent. For infrastructure teams standardizing on Juniper, the value is in expansion without disruption. You keep the operational model, preserve the investment in the EX4400 platform, and add the bandwidth needed for growth, segmentation, and higher-throughput uplinks. It is a targeted upgrade for environments that need more capacity, not more complexity.
