    Arista Compatible 800G OSFP Finned Top to 2x 400G OSFP Flat Top AEC Breakout Cable (1-meter, Active, OSFP to 2x OSFP, 26/28/30/32/34 AWG)

     

    QT-800G-O2OSFP-AExM is an 800G OSFP finned top to 2x 400G OSFP flat top active electrical cable (AEC) with pull-to-release slide latch design.  It is comprised of sixteen differential copper pairs, providing eight data transmission channels at speeds up to 106.25Gbps (PAM4) per channel. The AEC cable achieves 800 to 2x400Gbps signal conversion through 8 channels 100G-PAM4 to dual 4x100G-PAM4 signals for transmission, and it is backward compatible to 53.125Gbps (PAM4) and 25.78125Gbps (NRZ) operating modes.

     

    Available in a broad range of wire gages-from 26AWG to 34AWG, this 800G copper cable assembly features low insertion loss. The 800G OSFP AEC breakout cable supports both 800G Ethernet and InfiniBand Next Data Rate (NDR) systems, is ideal for rack-to-rack connectivity scenarios such as between router, server, storage, and switch.

      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.
