AddOn QSFP-4SFP10G-CU1M-AO 40GBASE-CU QSFP+ to 4xSFP | TAA, Copper — QSFP-4SFP10G-CU1M-AO

Break out one 40G QSFP+ interface into four SFP+ links with a direct-attach copper cable designed for short-reach aggregation. This 1 m assembly is a practical fit for dense rack environments where you need to fan out uplinks without adding transceivers, patch panels, or extra cable management overhead. For infrastructure teams, the value is in the simplicity: one cable, four endpoints, fewer components to source and track. That reduces points of failure and keeps deployment clean when connecting switches, servers, or storage gear that require compact, high-speed copper interconnects. TAA compliance also makes it easier to standardize procurement in regulated environments. Use it where short-distance, high-bandwidth connectivity matters and where a direct-attach path is preferable to a more complex optical design. The result is a straightforward way to extend 40G connectivity into multiple 10G links while preserving rack density and installation speed. Ideal For Fan out a 40G switch uplink to four 10G server or storage connections Connect adjacent rack equipment where short copper reach is sufficient Standardize TAA-compliant cabling for government or regulated procurement Reduce optical component count in dense aggregation layers Why This Product 1 Breaks out one 40G port into four 10G links 2 Uses direct-attach copper instead of separate optics 3 Supports compact short-reach rack deployments 4 TAA compliance suits regulated procurement
