QDD-2Q200-CU3M Overview
The Cisco 400G QDD-2Q200-CU3M passive copper cable provides a QSFP-DD to 2x QSFP56 200GBASE-CR4 breakout connection for very short reach links. With a reach of 3 meters, this direct attach cable enables high bandwidth connectivity from a 400G port to two 200Gbps ports.
Offering a cost-effective way to break out a 400G interface into 2x 200G ports, the QDD-2Q200-CU3M relies on host-based FEC. The 3 meter copper cable assembly supports 200Gbps per lane without requiring an external transceiver.
