Axiom Memory QDD-400-CU1.5M-AX 400G QSFP-DD Passive DAC

Create a direct 400G copper connection between two QSFP-DD interfaces without separate optical modules. Axiom Memory QDD-400-CU1.5M-AX is a 1.5 m passive copper direct-attach cable with a QSFP-DD connector at each end and Cisco compatibility. Its fixed-length cable assembly provides the complete interconnect between compatible ports rather than a pair of removable transceivers and a separate fiber patch cable. The 1.5 m reach fits short equipment-to-equipment runs inside a rack, including links between adjacent switches, server network adapters, storage systems, and routing platforms fitted with 400G QSFP-DD ports. Passive copper construction makes this cable appropriate where the installed ports are close enough to use a direct copper run. Both ends use the same QSFP-DD interface, so it is intended for straight QSFP-DD-to-QSFP-DD connections rather than mixed connector types. This cable is distinguished by its 400G signaling class, dual QSFP-DD termination, passive copper construction, and 1.5 m fixed length. Cisco compatibility addresses deployments that require a cable coded for Cisco equipment. Verify that both intended ports accept 400G QSFP-DD passive direct-attach copper cables and that the 1.5 m routing path reaches without excessive bend or strain.
