200G QSFP28-DD Breakout DAC cables include 200G QSFP-DD to 2x100G QSFP28 breakout copper cables and 200G QSFP-DD to 8x 25G SFP28 Passive Direct Attach Copper Breakout Cables. It splits the QSFP28-DD port of 200G signal (8x 25G-NRZ) into two QSFP28 ports of 100G signal (4x 25G-NRZ), or eight SFP28 ports of 25G signal (25G-NRZ). The 200G QSFP-DD breakout DAC splitter cables are high-speed, cost-effective alternatives to fiber optics in 200Gb/s Ethernet applications. The passive DAC uses simply copper wires and have no electronics, zero power consumption, and minimal latency and insertion losses. AscentOptics’ premium passive copper cable solutions provide power-efficient connectivity for short distance interconnects. It enables higher port bandwidth, density and configurability at low cost and reduced power requirement of data centers. It is compliant with QSFP28 MSA specification and supports SFF-8636 compliant I2C management interface.
