Cisco QSFP-H40G-AOC5M-RF 5 m 40GBASE AOC | Active Optical

Build cleaner short-reach 40 GbE links with Cisco’s QSFP-H40G-AOC5M-RF active optical cable. At 5 m, it gives infrastructure teams the reach needed for rack-to-rack and nearby row connections without the stiffness and cable mass that can complicate airflow and maintenance. Active optical cabling is a practical choice when you want predictable performance in a compact footprint. It helps reduce the clutter associated with separate optics and patch cords, while keeping the physical layer simple for standardized deployments. That matters in environments where every cable path affects serviceability, cooling, and port access. This remanufactured Cisco cable is a strong fit for organizations that value vendor alignment and cost discipline. It supports production refreshes, lab builds, and expansion projects where consistency across the optical layer reduces qualification effort. For teams comparing premium cabling options, the value is not just the link itself — it is the operational clarity that comes from using a purpose-built Cisco assembly.
