StarTech QSFP4X10GAO3 3 m 40 Gb AOC Breakout Cable

Use a breakout cable when one high-speed port needs to feed multiple 10 GbE endpoints without adding unnecessary complexity to the rack. This 3 m active optical assembly is designed for short, controlled runs where clean routing and dependable signal delivery matter more than raw distance. The breakout format is especially useful in dense environments that need to fan out a 40 GbE uplink into four 10 GbE links for access-layer switches, storage nodes, or clustered servers. Active optical construction helps keep the cable manageable while supporting the kind of link stability infrastructure teams expect when they are building around constrained space and high port utilization. This is a practical choice when you want to preserve bandwidth economics without overbuilding the cabling plant. Compared with lower-cost passive alternatives, an active optical breakout cable gives you a more disciplined path for short-reach fiber interconnects and a cleaner fit for production racks where uptime, airflow, and cable organization all matter.
