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. As a passive cable, it requires no external power, relying on host d romagnetic interference (EMI). Its robust desi d high-performance networking. The plug-and-play functionality simplifies d ed for active optical modules. Available in various lengths, it adapts to. The 400G QSFP-DD AOC is a high-performance module for short-range multi-channel data communication and interconnection applications. 125Gbps using OM3 fiber and up to 70m. The cable assembly meets IEEE 802. 3cd and Infiniband standards with substantial signal integrity margin providing high performance and. The 400G QSFP-DD DAC provides a QSFP-DD-to-QSFP-DD copper direct-attach solution and it is suitable for very short links and offer a cost-effective way to establish a 400-Gigabit link between QSFP-400G ports of switches/routers within racks and across adjacent racks. They connect servers, switches, and storage at speeds from 40G to 400G and beyond.
