Cisco QSFP-100G-AOC3M= 100GBASE QSFP Active Optical Cable, 3 m | Fiber Optic — QSFP-100G-AOC3M=

Move 100 GbE traffic between adjacent racks without the weight, bend radius, or airflow penalties of copper. Cisco QSFP-100G-AOC3M= is a 3 m active optical cable designed for QSFP-based 100GBASE interconnects where short-reach performance and cleaner cable management matter. For infrastructure teams building dense leaf-spine fabrics, this cable helps keep pathways organized and ports accessible. The integrated active optical design supports a lighter, more flexible run than equivalent copper assemblies, which can simplify routing in high-port-count environments and reduce strain on front-panel connections. It is a practical fit for short-distance links between switches, servers, and storage systems in the same row or adjacent cabinets. When uptime depends on predictable physical-layer connectivity, choosing the right cable matters as much as choosing the switch. This model is built for that role: short, direct, and purpose-made for 100 GbE QSFP deployments where every inch of rack space counts. Ideal For Connect top-of-rack and aggregation switches in adjacent cabinets Link servers to 100 GbE switches in the same row Patch storage arrays into high-speed fabric uplinks Reduce cable bulk in dense data center rack layouts Why This Product 1 Shorter 3 m reach for adjacent-rack links 2 Active optical design reduces cable bulk 3 QSFP-to-QSFP connectivity for 100 GbE fabrics 4 Better cable management than direct-attach copper in dense racks
