Cisco QSFP-H40G-AOC15M 15 m 40 GbE AOC Cable

Move 40 GbE traffic across longer rack-to-rack distances with this 15 m active optical cable. Designed for Cisco QSFP-H40G-AOC15M compatibility, it provides a clean optical path for high-speed interconnects where passive copper would be too heavy, too stiff, or too limited in reach. At 40 Gbps, this AOC is suited to environments that need predictable throughput and tidy cable management across adjacent rows, top-of-rack switches, or aggregation layers. The optical construction helps keep weight and bend stress down compared with traditional copper assemblies, which matters when you are building dense switch fabrics and want to preserve airflow and serviceability. This cable is a strong choice when the goal is to connect equipment quickly and keep the physical layer simple. For teams standardizing on Cisco-compatible QSFP optics, it offers the reach needed for production layouts without forcing a redesign of the rack plan.
