    Cisco QSFP-4SFP25G-CU2M Compatible 100G QSFP28 DAC Breakout Cable (2-meter, Passive, 100G QSFP+ to 4x25G SFP28)

     

    Cisco QSFP-4SFP25G-CU2M compatible 100G QSFP28 DAC breakout cable is comprised of a Twinax copper cable terminated with a QSFP28 form factor module on one end and four SFP28 form factor modules on the other end. This 100G QSFP28 Breakout DAC is verified to interoperate with original Cisco switches, including the Catalyst 9300X/9500/9600 and Nexus 3000/9200/9300/9500/9800 series. This cable cable has the advantage of convenient installation since the structure of modules is permanently attached to each end.

     

    100G QSFP28 to 4x25G SFP28 breakout cable is suitable for very short-distance transmission. It provides a cost-effective and low-power consumption solution for 100G to 25G breakout applications.

    Questions & Answers

    • All (5)
    • 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.
