AddOn CAB-Q-S-1M-AO 40GBASE-CU QSFP+ to 4x SFP+

Keep 40 GbE links tight, clean, and cost-controlled in high-density racks. The AddOn CAB-Q-S-1M-AO is a TAA-compliant direct attach copper cable designed as an Arista Networks CAB-Q-S-1M compatible replacement for short-reach 40GBASE-CU deployments. It connects a QSFP+ port to four SFP+ endpoints, making it a practical fit for aggregation, breakout, and interconnect scenarios where fiber is unnecessary and cable management must stay simple. This cable is built for environments that value deterministic short-run connectivity and procurement flexibility. Copper DAC assemblies reduce transceiver count, simplify ordering, and help keep deployment timelines moving when you need a compatible alternative to OEM-branded cabling. For infrastructure teams standardizing on Arista switching, the TAA-compliant designation supports government and regulated purchasing requirements without adding complexity to the rack. Use it where short-distance 40 GbE transport is enough and reliability matters more than overbuying optics. The result is a cleaner bill of materials, fewer components to track, and a direct path to stable connectivity between compatible network devices.
