Questions & Answers

more+
  • 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.
  • Once I place an order for my direct attach cables, how long will it take to receive them?
    QSFPTEK has been maintaining adequate stock level of kinds of Direct Attach Copper Cables in the warehouse. As long as the products you order are all in stock, we will ship them out the same day you place your order. As for some specific products or products that have a short stock, we will keep you informed ahead of time before you place your order.

    Compared to other high-speed networking technologies such as optical fiber, 40G DAC cables are generally more cost-effective, making them an attractive option for organizations that need high-speed connectivity but have budget constraints.
