Cisco QSFP-H40G-AOC2M= 40GBASE Active Optical Cable, 2m | QSFP, Enterprise — QSFP-H40G-AOC2M=

Maintain 40 GbE connectivity in tight rack environments with Cisco’s 2 m active optical cable. Built for QSFP-based links, it provides a short-reach optical interconnect that helps preserve signal integrity where passive copper DACs can fall short on reach or cable management. The result is a cleaner path between adjacent devices, with less bulk and better airflow than thicker copper alternatives. This cable is a practical fit for high-density switching, top-of-rack aggregation, and short interconnects inside the same cabinet or neighboring racks. Active optical design supports longer short-range runs than passive copper while keeping the installation simple: no separate transceivers, no patch panels, and no extra fiber assembly to manage. For teams standardizing on Cisco infrastructure, it offers a direct, purpose-built option that aligns with enterprise deployment requirements. Choose this model when you need predictable 40 GbE connectivity in a compact form factor and want to avoid the distance and bend-radius constraints of copper. It is a focused solution for environments where every inch of rack space and every cable path matters. Ideal For Connect adjacent Cisco switches in the same rack Link top-of-rack switching to nearby servers Bridge equipment across neighboring racks in a data center row Replace bulky copper cabling in dense 40 GbE deployments Why This Product 1 Shorter and cleaner than passive copper for dense rack routing 2 Integrated optical assembly reduces cabling complexity 3 2 m reach suits adjacent-device interconnects 4 Cisco-branded QSFP compatibility for enterprise environments
