NVIDIA Mellanox LinkX 200G QSFP56 Direct Attach Copper Cable, 2m, Black MCP1650-H002E26

Direct Attach Copper cable engineered for 200G Ethernet and HDR InfiniBand, delivering reliable high-speed connectivity in dense data center environments. This 2-meter QSFP56 to QSFP56 passive DAC provides low-latency, low-power interconnect for modern high-performance computing and storage systems.

Advantages

Passive design consumes less than 0.5W per end, reducing operational costs and thermal load. 30 AWG conductors balance flexibility and signal integrity, while the black PVC jacket ensures durability and easy identification. Fully compliant with SFF-8665 and RoHS, it guarantees interoperability with NVIDIA Mellanox and other QSFP56 ports.

Suitable for

• Data center top-of-rack to server connections
• High-performance computing clusters requiring HDR InfiniBand
• Storage area networks and hyper-converged infrastructure
• Any QSFP56-compatible switch, NIC, or adapter

Key specifications
