Questions & Answers

  • All (6)
  • 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.
  • 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.
  • 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.

    We had been using traditional fiber optic modules but decided to try a 10G DAC and the results were exactly as expected. First of all, 10G DAC greatly reduces our costs in short-distance connections, and its performance is not inferior to fiber optic solutions. It is also faster to install than fiber optics, making it especially suitable for our server architectures that require dense connections.

    I bought some 10G DACs for internal connections in the rack. They are plug-and-play and have stable transmission. I received the products on the third day after placing the order. The express delivery was very fast. The account manager responded quickly and patiently answered my questions.

    I was amazed by the very fast shipping, usually it takes a while for other companies to ship, I also confirmed the package when I received it. I tested it after receiving it, it works very well, the data transmission is stable, plug and play. It is a great shopping experience to buy such a good product at such a price.

    I'm using these to connect multiple switches, these switches are Aruba 2930F-48G-740W-PoE+-4SFP+, and this DAC cable is very useful, while ensuring the quality of the transmitted data, he attracted me at a lower price, so I can use that part of the budget for other things.

    works as expected. Run it with Intel x520-DA1. Had an SFP+ DAC cable from another manufacturer before, but the x520 refused to recognize it (no fix/set in linux driver). This DAC from QT recognizes and works fine without setting it in the driver. A very good shopping experience, I will come back to buy again when I need it.

    I had previously purchased a cable from another company which was more expensive and didn't work with my Aruba switch. However, this cable worked perfectly and was also cheaper.

    I was working away from home and needed some cabling, but I had been overlooked during the planning stage. Luckily, I was able to find exactly what I needed at QSFPTEK.COM, and I placed my order. The cabling worked perfectly and I was able to save money on the project.
