Cisco 400G QSFP-DD Active Optical Cable, 10M | QSFP-DD, 400G

Build 400G links with less clutter and fewer moving parts. Cisco’s 10 m QSFP-DD active optical cable is designed for environments where high bandwidth must be delivered within a compact physical span. By combining the optical path into a single cable assembly, it reduces the number of components in the link and helps keep rack layouts organized. This 10 m model is a practical choice for same-row or short adjacent-rack connections in data centers that depend on 400G switching. The QSFP-DD interface aligns with modern high-density platforms, while the active optical design supports the signal characteristics needed for high-speed transport over distances that exceed what passive copper is typically suited for. For infrastructure teams standardizing on Cisco hardware, this cable provides a direct way to connect compatible 400G ports without adding unnecessary complexity. It is especially useful where airflow, cable bend management, and predictable deployment are part of the design standard. When the architecture calls for a shorter 400G optical link, this cable keeps the physical layer simple and purpose-built.
