Cisco QDD-400-AOC15M= 400G QSFP-DD Active Optical Cable, 15M

Keep 400G traffic moving between racks with a Cisco active optical cable designed for QSFP-DD environments. The 15 m reach gives infrastructure teams the flexibility to connect adjacent cabinets, top-of-rack switches, and high-density compute or storage nodes without introducing the weight, stiffness, or signal limitations of long copper assemblies. This cable is a strong fit for data center builds where port density, airflow, and cable management matter as much as throughput. Active optical design supports clean routing in crowded enclosures and helps preserve the physical discipline required in modern fabric architectures. For teams standardizing on Cisco optics and interconnects, it offers a direct path to predictable deployment and consistent interoperability across 400G links. Choose this model when you need more than a generic patch cable. The QSFP-DD form factor, 15 m length, and Cisco part-specific compatibility make it suitable for production networks where downtime, rework, and cable clutter carry real cost. It is built for environments that demand fast installation, stable performance, and a cleaner rack layout at scale.
