Cisco 400G QSFP-DD Active Optical Cable, 7 m | QSFP-DD, 400G

Maintain 400G connectivity across short interconnect runs with Cisco’s 7 m QSFP-DD active optical cable. Designed for dense switching and routing environments, it replaces heavier copper assemblies with a lighter optical path that helps keep racks organized and airflow unobstructed. The 7 m length fits common top-of-rack to adjacent-rack deployments, where cable management and port accessibility matter as much as throughput. By using an active optical design, it supports high-speed transport without the bend-radius and weight penalties that can complicate large-scale deployments. This cable is a strong fit for teams standardizing on 400G infrastructure and looking to preserve port density without adding unnecessary complexity. It is especially useful in environments where clean routing, reduced congestion, and consistent physical layout support faster maintenance and fewer installation delays. For infrastructure teams investing in high-capacity fabric upgrades, this Cisco AOC provides a direct path to 400G connectivity with the fit, finish, and deployment discipline expected in enterprise networks.
