Cisco QSFP-4X10GAOC3M-RF 3 m 40GBASE AOC | QSFP Breakout — QSFP-4X10GAOC3M-RF

Keep short-reach 40 GbE links clean, direct, and easy to manage with Cisco’s QSFP-4X10GAOC3M-RF active optical breakout cable. Designed for QSFP-to-4x SFP+ connectivity over 3 m, it supports dense switch-to-server or switch-to-switch deployments where copper would add bulk, weight, and airflow concerns. Active optical cabling is a strong fit when you need consistent signal integrity across a compact span without introducing the complexity of separate transceivers and patch cords at every endpoint. The breakout design simplifies aggregation and fan-out in modern racks, helping infrastructure teams maintain orderly pathways in high-port-count environments. As a remanufactured Cisco part, this cable is positioned for organizations that want enterprise-grade compatibility while controlling spend on recurring infrastructure purchases. It is well suited to refresh cycles, lab environments, and production networks where standardized Cisco optics and cabling reduce qualification risk. For teams planning around uptime, serviceability, and rack density, this cable delivers the practical advantages that justify choosing a branded breakout assembly over generic alternatives.
