AddOn QSFP-H40G-CU2M-AO 40G QSFP+ Twinax Cable

Keep high-speed switch-to-switch and switch-to-server links clean, short, and predictable with this AddOn passive twinax direct attach cable. Designed as a Cisco QSFP-H40G-CU2M compatible 40GBase-CU solution, it provides QSFP+ to QSFP+ connectivity at up to 2.0 m, making it a practical fit for adjacent rack and same-cabinet deployments where optical transceivers add cost and complexity. This cable is programmed, uniquely serialized, and data-traffic and application tested to support consistent deployment outcomes. Its passive copper design reduces power draw and removes the need for separate optics on short runs, while MSA compliance supports interoperability in mixed infrastructure environments. TAA compliance also makes it suitable for organizations with sourcing requirements tied to public sector or regulated procurement. For teams standardizing 40 GbE access and aggregation layers, this cable offers a straightforward path to reliable connectivity without overbuying on reach or hardware. It is built for network devices that need a verified, direct attach link with the right balance of performance, compliance, and procurement clarity.
