QSFP+ 40 Gbps passive DAC cable

This passive Direct Attach Copper twinax cable uses QSFP+ connectors on both ends to deliver 40 Gbps links with near-zero power draw and latency lower than RJ45. It is built for short-range structured cabling between switches, routers, servers and storage in top-of-rack or adjacent-rack layouts up to 7 m. The 10 ft length and 30 AWG conductors suit rack-to-rack runs inside a single cabinet or between neighbouring racks. MSA compliance keeps it compatible with a broad range of network equipment.

Suits short-haul 40 GbE links; not for longer runs

Network teams needing cost-effective, low-latency 40 GbE connections inside a rack or to an adjacent rack will benefit from the passive design that consumes less than 0.15 W and operates up to 70 °C. Buyers who need reaches beyond 7 m or who require optical isolation for EMI-sensitive environments should look at active optical or fiber solutions instead. The cable is not intended for outdoor, plenum or extended-distance deployments.

10 ft 30 AWG passive twinax with dual QSFP+

The single specification that decides fit is the 10 ft passive twinax construction rated for 40 Gbps over QSFP+ ends. At 30 AWG it supports the stated 7 m maximum for passive DAC, so verify that your rack-to-rack distance stays within that limit. If the link exceeds 7 m or your switch ports require active cables, this part will not work.

Questions about this item

Do I need two QSFP+ ports on my equipment for this 40 Gbps DAC cable to work?

Yes, the cable has QSFP+ connectors on both ends and requires a matching QSFP+ port on each device to achieve 40 Gbps data transfer.

Will this passive twinax cable work with my existing 40GbE switches from Cisco or Ubiquiti?

The cable is MSA-compliant and designed for compatibility with leading manufacturers including Cisco, Ubiquiti, TP-Link, ZyXEL and Intellinet Network Solutions switches.

How can I confirm the link is running at the full 40 Gbps after I connect the cable?

Check the port status on each switch or router; it should show a 40 Gbps link with no errors, and the connection will consume less than 0.15 W of power.
