800G QSFP-DD Passive DAC Twinax Cable – (QSFP-DD to QSFP-DD)
The 800G QSFP-DD Passive Direct Attach Copper (DAC) Twinax cable is engineered for ultra-high-speed 800G Ethernet connectivity in next-generation data centers. Designed for short-reach interconnects, it enables reliable, low-latency communication between 800G QSFP-DD ports in high-density switching environments.
This passive copper cable integrates 8 high-speed differential lanes, each supporting up to 100Gb/s using PAM4 modulation, delivering an aggregate bandwidth of 800Gbps. It complies with IEEE 802.3ck and QSFP-DD MSA specifications, ensuring interoperability and industry-standard compatibility.
By eliminating the need for separate optical modules and patch cords, this DAC solution significantly reduces cost, power consumption, and deployment complexity in short-distance applications.
