Move 400G traffic into four 100G lanes without adding transceivers, patch panels, or extra conversion points. This Axiom active optical breakout cable is designed for Juniper-compatible deployments that need clean, high-density interconnects between switches, aggregation layers, and adjacent racks. The QSFP-DD end presents a single 400G link, while the four QSFP56 ends distribute that bandwidth into 100G connections for equipment that is already standardized on 100G optics. At 5 m, it fits short-reach data center runs where airflow, cable management, and port density matter as much as throughput. Compared with piecing together separate optics and patching, an AOC breakout simplifies the path between devices and reduces the number of components in the link. That means fewer points to manage during deployment and a cleaner physical layer for high-value infrastructure. For teams building around Juniper switching platforms, this cable helps preserve rack density while matching the speed profile required by modern spine-leaf and aggregation designs.
