Axiom X66120-3-AX 40GBASE-CR4 QSFP+ to 4x SFP+ 3 m DAC

Move traffic cleanly from a 40 GbE uplink to four 10 GbE connections with a passive DAC built for short-reach breakout applications. This Axiom cable uses a QSFP+ host end and four SFP+ device ends, making it a practical fit for storage, switching, and aggregation layouts where a single high-speed port needs to feed multiple lower-speed links. The 3 m length gives enough reach for adjacent racks or within-cabinet routing without adding unnecessary slack. Passive direct-attach copper is a strong choice when you want low-latency, power-free connectivity for short distances. It avoids the complexity of optics and transceivers while keeping cabling straightforward and cost-conscious for dense infrastructure. In NetApp-compatible deployments, that matters: you get a purpose-built breakout path that supports clean port utilization and predictable physical layout. For teams balancing performance, density, and budget, this cable fills a specific role. It is not a general-purpose patch cord; it is a targeted interconnect for 40GBASE-CR4 to 4 x 10GBASE-CU breakout scenarios where compatibility and cable discipline are part of the design.
