Our take on the Extreme Networks 40G-DACA-QSFP1M 1 Meter 40GbE QSFP+ to QSFP+ Direct Attach Active Optical Cable

This is a 1-meter 40GbE QSFP+ to QSFP+ active optical cable from Extreme Networks, built for short rack-to-rack and switch-to-switch links in data centers. Active optical construction carries 40GbE over a thin, light cable with better reach and EMI immunity than passive copper DACs at the same length. It suits network engineers wiring Extreme switches and other QSFP+ ports inside a rack or between adjacent racks. Compared with generic third-party QSFP+ AOCs, it is the vendor-branded part, which matters most where support and compatibility with Extreme gear are required.

Pros
  • Active optical design for 40GbE over 1 meter
  • Thin, light cable that is easier to route than copper
  • Immune to most electromagnetic interference
  • Vendor-branded for Extreme Networks compatibility
  • QSFP+ connectors on both ends
Cons
  • Short 1-meter length limits placement
  • Only useful for 40GbE QSFP+ ports, not 100GbE
  • Active optics cost more than passive copper DACs
  • Branded part ties you to Extreme ecosystems

Questions and answers

Is this cable active or passive?
It is an active optical cable, so it converts electrical signals to light inside the connector housings. That makes it lighter and more interference-resistant than passive copper at the same length.
What speed and connector does it support?
It carries 40GbE over QSFP+ connectors on both ends. It will not link 100GbE QSFP28 ports at full speed.
How long is it?
It is 1 meter long, suited to links between switches in the same rack or adjacent racks.
Does it work with non-Extreme switches?
QSFP+ ports are standardized, so it often works in other vendors' QSFP+ ports, but compatibility is not guaranteed outside Extreme Networks gear.
Is it worth choosing over a copper DAC?
For very short runs, a passive copper DAC is usually cheaper. This cable makes sense when you want a thin, light, interference-immune link or vendor-backed compatibility.
Where is the Extreme Networks 40G-DACA-QSFP1M 1 Meter 40GbE QSFP+ to QSFP+ Direct Attach Active Optical Cable cheapest?
