Questions & Answers

  • What's the difference of passive and active DACs?

    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 have used QSFPTEK products before. Bought twice from their website, both worked fine, engineer communication was excellent and reliable. BTW, their DACs do not include shipping, but are still extremely cheap.

    The quality of the cables is very good, the same as what we get from other high-end brands.

  • Reagan DECKER United States of America

    I used your network cable instead of the original because the data transfer from and to the original makes no difference but is much lower and can cost a lot of money. thank you very much.

  • Duane Johnston United States of America

    We are a laboratory so very strict about the quality of the DAC twinax cables. I've bought many optical patch cables from QSFPTEK before and their products are always with good quality. So I decided buy 1pc for test at first. My sale representative Talia has sent me detailed test reports with different switches on their test center before shipment. Thanks a lot for her kind help. I've already tested the cable and it works well. I'll buy it again soon.

  • Margaret Terry United States of America

    I used to buy a lot of 10G and 40G DAC/AOC cables from QSFPTEK for my switch room and they always did a great job. My 100G DAC sample order also works fine.
