400G Direct Attach Copper (DAC) cable is a high-speed, cost-effective interconnect solution designed for short-reach data transmission within high-performance computing environments. These cables consist of a twinax copper assembly terminated with industry-standard transceiver modules, such as. Upgrading a data center to 400G requires more than just swapping out switches. As bandwidth demands surge, choosing the right direct attach copper (DAC) solution becomes a critical. Innoptical's IN-DAC-400G-Dxxx QSFP-DD passive copper cable assembly feature eight differential copper pairs, providing four data transmission channels at speeds up to 56Gbps (PAM4) per channel, and meets 400G Ethernet and InfiniBand Enhanced Data Rate (EDR) requirements. Available in a broad range. The 400G DAC features two 400G QSFP-DD connectors and one passive copper cable, providing 400G data rates.
