200G QSFP28-DD(Double-Density) DAC cables are passive Direct Attach Copper (DAC) cables as high speed, cost-effective alternatives to fiber optics in 200G Ethernet applications.
The 200G QSFP-DD DAC cable contains 16 high-speed copper pairs, each operating at data rates of up to 25Gb/s of NRZ signals. It is compliant with QSFP28 MSA and supports the SFF-8636 compliant I2C management interface. AscentOptics’ 200G QSFP-DD 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 requirement in the high-performance computing (HPC), data center and storage networks. The 200G QSFP-DD direct attach cables length range from 0.5 meter to 5 meters.
