Extreme Networks 40G-DACP-QSFPZ5M 0.5m Passive DAC

Build short, efficient 40 GbE connections with the Extreme Networks 40G Passive DAC QSFP+ 0.5 m cable. This direct attach copper assembly is designed for QSFP+ ports and is well suited to top-of-rack and adjacent-device links where distance is short and signal integrity is easier to maintain. By using a passive DAC instead of optics, you can simplify the bill of materials and reduce power consumption at the edge of the rack. The 0.5 m length is ideal when switches, servers, and storage nodes sit in close proximity. That shorter reach helps keep cable management clean and airflow less obstructed, which matters in dense infrastructure where every inch of rack space counts. For teams standardizing on 40 GbE, DAC cabling is often the most practical choice for predictable, low-complexity interconnects. This cable fits environments that value direct, purpose-built connectivity over unnecessary hardware layers. It is a straightforward way to connect compatible QSFP+ ports with the right length, the right interface, and the right economics for short-run 40 GbE deployments.
