40G QSFP+ Passive DAC Cable

The Intellinet Network Solutions 508506 is a three-foot passive Direct Attach Copper twinax cable with QSFP+ connectors on both ends. It targets data-centre and enterprise installers who need 40 Gbps links between switches, routers, servers or storage over short distances.

MSA-Compliant Plug-and-Play Installation

The cable follows the QSFP+ MSA specification, so it works with switches from Cisco, Intellinet Network Solutions, ZyXEL, TP-Link, Ubiquiti and other compliant vendors without configuration. No transceivers or separate patch cords are required, reducing the number of components that must match. The only common issue is exceeding the seven-metre passive reach limit, which forces a move to active or optical alternatives.

40 Gbps Throughput Within Seven Metres

The twinax construction delivers 40 Gbps with latency lower than RJ45 and power draw below 0.15 W, operating up to 70 °C. It comfortably handles top-of-rack, adjacent-rack and switch-stacking runs up to 23 ft. Beyond that distance the passive design runs out of signal margin and an active or fibre solution becomes necessary.

Highlights

  • Passive DAC saves power with under 0.15 W draw
  • MSA-compliant QSFP+ ends work with major switch brands
  • 40 Gbps throughput over 3 ft copper twinax
  • Lower latency than RJ45 for short rack links
  • Simpler deployment than optics with no transceivers needed

Questions about this item

How can I verify the 40 Gbps link is active after connecting the QSFP+ ends?

Check the switch or router port LEDs and run a 40 Gbps throughput test; the passive DAC introduces no firmware so the link lights and speed negotiation confirm correct operation.

What comes in the box and what must I source separately?

The box contains only the 3 ft 30 AWG QSFP+ to QSFP+ passive twinax cable; you must provide compatible QSFP+ ports on both switches, routers or servers.

When should I choose this 3 ft 30 AWG version instead of a longer or thicker gauge cable?

Select this 3 ft 30 AWG model for short rack or adjacent-rack runs up to 7 m where low latency, under 0.15 W power draw and 70 °C operating range are required.
