The Generic compatible 800G QSFP-DD DAC is designed for use in 800G Ethernet applications. It contains 8 high-speed differential pairs (lanes), each operating at data rates of up to 100Gb/s. This cable is compliant with IEEE 802.3ck Ethernet standard and QSFP-DD MSA (Multi-Source Agreement).
With the advantages of low cost, low power consumption, interchangeability, etc, it is an ideal solution for short-distance interconnects and enable higher port bandwidth, density and configurability between data center racks. It also offers a more cost-effective solution than deploying discrete QSFP-DD modules with separate patch cords.
