The 200G QSFP56 Direct Attach Copper (DAC) Cable is a high-performance, cost-efficient solution for short-reach 200G Ethernet and HDR interconnects. Designed for modern data centers, cloud platforms, AI/ML clusters, and high-density switching environments, this passive copper cable eliminates the need for optical modules while providing exceptional signal integrity and ultra-low latency.
Each cable is built with 8 high-speed copper pairs, supporting 4×53Gb/s PAM4 lanes, and features fully QSFP56 MSA-compliant connectors. An integrated EEPROM in each QSFP56 housing provides host-readable product data for seamless system integration.
