Our take on the Extreme Networks 40G-DACP-QSFP5M 5 Meter 40GbE QSFP+ to QSFP+ Direct Attach Passive Copper Cable

This is a 5-meter passive copper direct attach cable with QSFP+ connectors on both ends, built for 40GbE links between switches, routers and servers. Passive copper is the cheapest way to run short 40G runs, and it draws no power and adds no measurable latency, unlike active optical cables. It suits data center and lab racks where two 40G ports sit within a few meters of each other. Compared with fiber optics it is simpler and more durable for in-rack cabling, but it is bulkier and limited to short distances.

Pros
  • Passive design draws no power and needs no transceivers
  • No added latency versus active or optical links
  • Rugged copper build tolerates frequent re-cabling
  • QSFP+ on both ends for 40GbE ports
  • Extreme Networks part number for matching existing gear
Cons
  • Limited to short runs; not for long distances
  • Thicker and stiffer than fiber, harder to route tightly
  • Only works between QSFP+ 40G ports, not 10G SFP+
  • No optics inside, so no monitoring or diagnostics

Questions and answers

Will this work between two 40G QSFP+ switch ports?
Yes. It is a QSFP+ to QSFP+ passive copper cable made for 40GbE links between compatible ports on switches, routers and servers.
Can I use it to connect 10G SFP+ ports?
No. QSFP+ connectors do not fit SFP+ cages. For 10G links you need an SFP+ DAC or SFP+ optics.
Is a passive DAC slower than an active optical cable?
No. Passive copper adds no measurable latency. It is simply limited to shorter distances than optical cables.
How far can a 5-meter passive DAC reach?
Five meters is within the typical passive copper range for 40GbE. Longer runs usually call for active copper or fiber.
Does it need power or configuration?
No. It is a passive cable with no electronics, so it needs no power and no setup beyond plugging it in.
