Link adjacent high-speed network devices with a fixed 3 m passive copper connection. Accortec QSFP-200-CU3M-ACC carries 200G traffic between QSFP56 ports, making it suited to short-reach connections inside racks and between nearby rack-mounted systems. Its QSFP56-to-QSFP56 construction keeps both ends on the same high-density interface type rather than adapting between different connector formats. This direct-attach cable fits deployments connecting compatible Cisco network equipment, including high-speed switching, routing, server, and storage interfaces fitted with QSFP56 ports. Passive copper is appropriate where equipment placement remains within the cable's 3 m reach and where a fixed cable assembly is preferred over separate optical modules and patch fiber. Both endpoints require QSFP56 interfaces capable of accepting a 200G passive copper connection. The specific configuration combines 200G signaling, QSFP56 terminations at both ends, passive copper construction, and a 3 m cable length. That combination distinguishes it from longer-reach links, optical assemblies, and cables with mixed connector types. TAA compliance supports installations with applicable trade-agreement sourcing requirements, while Cisco compatibility targets environments standardized on compatible Cisco QSFP56 equipment.
