AddOn QSFP-4SFP10G-CU2M-AO 40GBASE-CU QSFP+ to 4x SFP+ Cable | TAA — QSFP-4SFP10G-CU2M-AO

Keep short-reach 40 GbE links simple with a direct-attach cable built for dense switch-to-switch connectivity. This AddOn Networks assembly maps a QSFP+ host interface to four SFP+ endpoints, making it a practical fit for environments that need high-bandwidth interconnects without the cost and complexity of separate transceivers and fiber patching. At 2 m, it is sized for adjacent rack or same-row deployments where signal integrity and cable management matter. The direct-attach design reduces component count, shortens install time, and helps maintain a cleaner path between aggregation and access layers. For procurement teams, TAA compliance supports public-sector and regulated purchasing requirements. For operators, it means a straightforward way to extend 40 GbE connectivity while keeping the bill of materials tight. Use it where predictable short-distance throughput matters more than optical flexibility: top-of-rack to aggregation, leaf-spine adjacency, or lab environments that need repeatable, low-friction interconnects. When the goal is to move traffic reliably between compatible ports, this cable delivers the right interface conversion in a compact form factor. Ideal For Top-of-rack to aggregation switch uplinks in the same rack row Leaf-spine interconnects where short copper runs are preferred Lab and staging environments validating 40 GbE port compatibility Procurement-controlled deployments requiring TAA-compliant cabling Why This Product 1 Breaks out one QSFP+ port to four SFP+ connections 2 Uses direct-attach copper instead of separate optics 3 Sized for short rack-to-rack or within-rack runs 4 Supports TAA-compliant procurement workflows
