Questions & Answers

  • What's the difference of passive and active DACs?
    The active DAC has longer transmission distance which can reach 12m, while the passive DAC supports transmission within 10m.
  • Can I have different compatibilities for each end of my direct attach cables?
    Yes, QSFPTEK offers customized dual compatibility solutions for direct attach cables so that you can choose compatibilities for each end individually. Just contact your sales rep. for detailed compatible customization on dual ends.
  • Why should I trust QSFPTEK compatible direct attach cables?
    Exceting the price advantage we have compared to branded cables, QSFPTEK DACs also maintain the same performance and reliability. To satisfy our customers' needs of high performance, all of our DACs are tested multiple times in mainstream original brand switches in our test center before shipped out. What's more, using compatible optics in brand devices will not negatively affect manufacturers' warranty if that's your concern.

    I've tried other brands of breakout cables and they work just fine without the QSFPTEK. These days, we plan to buy new equipment for our project, and we will still choose QT as the first site.
