Cisco 400G QSFP-DD Active Optical Cable, 2M | Data Center Fiber

Keep 400G interconnects tight, orderly, and ready for high-density switching with Cisco’s 2 m QSFP-DD active optical cable. Designed for short-reach data center links, it helps maintain signal integrity while avoiding the weight, bend radius, and airflow penalties of thicker copper assemblies. This cable is a practical fit for top-of-rack to spine connections, adjacent rack uplinks, and other short-span deployments where port density matters. The QSFP-DD form factor supports modern 400G infrastructure, while the active optical design is suited to environments that need cleaner cable management and consistent performance across short distances. For teams standardizing on Cisco optics and interconnects, this cable offers a straightforward way to keep high-speed fabrics compact and serviceable. It is the kind of component that pays off in the rack: less congestion, easier tracing, and a cleaner path for airflow around critical switching hardware.
