Cisco QDD-400-AOC15M 400G QSFP-DD Active Optical Cable, 15M | Data Center

Built for short-reach 400G interconnects, this Cisco active optical cable helps keep modern data center fabrics organized and serviceable. The 15 m length is well suited to rack-to-rack and cabinet-to-cabinet runs where copper can become unwieldy, especially in environments that already push the limits of port density and airflow. Active optical construction supports a lighter, more flexible path between QSFP-DD ports, making installation easier in crowded enclosures and reducing the physical strain that often comes with high-speed cabling. For teams operating at 400G, that matters: cleaner routing improves maintainability, and a purpose-built cable reduces the risk of mismatched components in production. This model is a practical choice for infrastructure teams that want Cisco-specific sourcing for critical links. It is designed for deployments where consistency, fit, and cable management are part of the performance equation. When the network is dense and the stakes are high, a cable built for the job is worth more than a generic alternative.
