AddOn Cisco to Mellanox 40GBASE-CU QSFP+ Passive DAC 2 m

Maintain high-speed connectivity between compatible Cisco and Mellanox equipment with a passive 40GBASE-CU QSFP+ direct attach cable designed for short-run interconnects. At 2 m, it is well suited for adjacent rack connections, top-of-rack switching, and other tightly controlled deployments where signal integrity, latency, and cost efficiency matter. Direct attach copper keeps the link simple: no separate transceivers, no extra fiber patching, and fewer points of failure. That makes this cable a practical choice for infrastructure teams standardizing 40 GbE links in environments that value predictable performance and straightforward installation. The passive design is ideal for short distances where active electronics are unnecessary. For procurement teams, the value is in matching the right cable to the right job. This MPN is positioned for compatibility-focused deployments that need a dependable QSFP+ interconnect without paying for features that do not improve short-range performance. It is a clean fit for data center racks, lab environments, and switch staging where speed, simplicity, and budget discipline all matter.
