200G DAC Cable QSFP56 to QSFP56 Passive Twinax Cable

SVNK 200G QSFP56 Passive Direct Attach Copper (DAC) Cable

The SVNK 200G QSFP56 Passive DAC cable is a high-performance, cost-effective copper interconnect solution engineered for 200 Gigabit Ethernet and InfiniBand EDR short-reach applications. Designed for ultra-high-speed connectivity within racks and across adjacent racks, it provides a reliable alternative to optical modules for environments requiring low latency, low power consumption, and optimized total cost of ownership (TCO).

SVNK QSFP56 passive copper assemblies feature eight differential copper pairs, supporting four high-speed PAM4 channels, each operating at data rates of up to 53.125 Gb/s, delivering an aggregate bandwidth of 200 Gb/s. Built using precision twinax cable technology, these assemblies deliver excellent signal integrity, low insertion loss, and minimal crosstalk, meeting the stringent requirements of PAM4 signaling.

Available in a wide range of wire gauges from 26AWG to 30AWG, SVNK 200G DAC cables are optimized for flexibility, airflow efficiency, and high-density installations. As a passive solution, they require no additional power, making them ideal for energy-efficient, short-distance high-speed interconnects.

Fully compliant with QSFP56 MSA, CMIS, SFF-8636, and IEEE 802.3 standards, SVNK 200G DAC cables ensure seamless interoperability with leading switches, routers, and network platforms.
