Cisco QDD-400-AOC2M 400G QSFP-DD Active Optical Cable, 2M | Data Center

Deliver 400 GbE connectivity across short distances without adding unnecessary cable bulk. This Cisco QSFP-DD active optical cable is designed for dense data center environments where high port counts and tight rack layouts demand disciplined cabling. At 2 m, it fits common intra-rack and adjacent-rack paths while helping preserve airflow and simplify physical management. Active optical cabling is a strong fit when you need high bandwidth in a compact footprint. Compared with heavier copper alternatives, it can make routing easier and reduce strain on front-panel connections in crowded switch deployments. That matters in leaf-spine fabrics, aggregation layers, and other environments where every cable path affects serviceability. For teams standardizing on Cisco optics, the QDD-400-AOC2M provides a straightforward way to extend 400 GbE links with the connector format expected by QSFP-DD platforms. It is a practical choice for infrastructure builds that prioritize density, clean installation, and consistent short-reach performance.
