10Gtek 400G QSFP-DD to 2X 200G QSFP56 Twinax Breakout Copper Passive DAC Cable, 3-Meter, 30AWG, for Arista CAB-D-2Q-400G-3M

["It’s a breakout cable with a 400G QSFP-DD connector on one end and two 200G QSFP56 connectors on the other. It enables flexible connectivity from a single 400G switch port to two 200G devices, ideal for high-density AI and HPC deployments.","Utilizes passive copper technology without power-hungry retimer chips. Operating at <0.1W, it generates minimal heat, reducing thermal load in crowded data center racks and lowering overall cooling costs.","Supports 400Gbps (8x 50G PAM4) to 2x 200Gbps breakout, delivering the stable, low-latency performance required for GPU cluster communication, AI training, and high-performance computing workloads.","100% compatible with Arista. 10Gtek owns Compatibility LAB to meet the coding requirements for various brands of switches and routers. Each cable is individually tested before delivery."]
