800G DAC Cable QSFP-DD to QSFP-DD Passive Twinax Cable

SVNK 800G QSFP-DD Direct Attach Copper (DAC) Cable

The SVNK 800G QSFP-DD Passive Direct Attach Copper (DAC) cable is a next-generation, high-performance, and cost-effective interconnect solution engineered to support 800 Gigabit Ethernet links in hyperscale data centers, AI clusters, high-performance computing (HPC), and storage networks.

Designed in compliance with the QSFP-DD MSA, IEEE 802.3ck, and CMIS specifications, this passive copper assembly supports 8×100G PAM4 electrical lanes, delivering an aggregate throughput of up to 800G with ultra-low latency, minimal power consumption, and excellent signal integrity.

The SVNK 800G QSFP-DD DAC is optimized for very short-reach, in-rack and adjacent-rack connections, providing a reliable and economical alternative to optical interconnects while enabling higher port density and reduced total cost of ownership.
