‧ Copper wire (DAC): suitable for short distance network lines below 3M

‧ Optical fiber cable (AOC): The optical fiber cable has high loss resistance and is suitable for network lines above 3M

‧800G QSFP-DD Passive Direct Attach Copper Cable (DAC) assemblies as a high-speed, cost-effective alternative to fiber optics in the server racks of 800G data center. It contains 16 high-speed copper pairs to support 8 signal channels with a data rate of up to 112Gb/s per channel, providing power-efficient connectivity for 800G short-distance interconnects up to 1.8 meters. It enables higher port bandwidth, density and configurability at a low cost and reduced power requirement in the data centers.
