AddOn X66120-3-AO 40GBASE-CU QSFP+ to 4xSFP+ DAC

Keep high-speed infrastructure tightly connected with a direct attach cable built for 40GBASE-CU deployments. The AddOn X66120-3-AO provides a QSFP+ to 4xSFP+ breakout path for environments that need to fan out one 40 GbE uplink into multiple 10 GbE connections without adding active optics. That makes it a practical fit for top-of-rack switching, storage networking, and aggregation layers where port density and predictable signal paths matter. TAA compliance supports procurement requirements for public sector and regulated environments, while the compatible design helps simplify sourcing for teams standardizing on NetApp X66120-3-class connectivity. Because this is a direct attach copper assembly, it is well suited to short-reach links inside the rack or across adjacent racks, where cost control and cable management are as important as throughput. For infrastructure teams balancing performance, compliance, and budget discipline, this cable offers a straightforward way to extend 40 GbE fabric capacity with fewer moving parts than transceiver-based alternatives.
