200G QSFP56 DAC cables are high speed, cost-effective alternatives to fiber optical transceivers in 200G Ethernet and 200Gb/s InfiniBand HDR applications. The QSFP56 direct-attach passive copper cable contains eight high-speed copper pairs, each operating at data rates of up to 50Gb/s with PAM4 modulation. It is compliant with SFF-8665, and supports an SFF-8636 compliant I2C management interface. AscentOptics’ high performance passive copper cable solutions provide power-efficient connectivity for short distance interconnects. It enables higher port bandwidth, density and configurability at low cost and low power requirements in high-performance computing (HPC), data center and storage networks. The 200G QSFP56 direct attach cables length range from 0.5 meter to 5 meters.
