Extreme Networks 40G-DACP-QSFP3M 3 m Passive DAC

Keep high-speed links short, direct, and predictable with this 3 m passive DAC for QSFP+ environments. It is designed for 40 GbE connections where the endpoints sit in the same rack or adjacent racks, and where a copper direct attach cable is more practical than an optical solution. Passive DACs are a strong fit for dense infrastructure because they avoid the added cost and power draw of transceivers while preserving a clean physical layer for short runs. That makes this cable especially useful in switch fabrics, top-of-rack deployments, and server aggregation layouts where cable management and port density matter. The 3 m length gives you enough reach for structured rack routing without excess slack. For procurement teams and network architects, this model fits the middle ground between minimal patch lengths and longer inter-rack runs, helping standardize 40 GbE connectivity with fewer moving parts.
