Mellanox / NVIDIA MCP1650-H001E26 200G QSFP56 DAC Passive Copper Cable 1m

The Mellanox MCP1650-H001E26 is a passive copper direct-attach cable (DAC) engineered for 200 Gbps interconnect applications. It delivers native support for 200G HDR InfiniBand and 200GbE Ethernet protocols, enabling lossless, low-latency fabric connectivity without active signal conditioning. The cable's passive design eliminates power consumption and heat generation, making it ideal for density-constrained deployment environments.

This 1-meter cable is optimized for short-reach, high-bandwidth cluster interconnects typical in AI accelerator pods and HPC environments. It employs QSFP56 connectors on both ends, ensuring compatibility with next-generation fabric switches and adapter cards that support 200G connectivity. The copper construction provides proven signal integrity and reliability across standard enterprise operating conditions.

Launched in Q3 2020, this cable has become standard infrastructure for organizations scaling distributed AI training clusters and real-time analytics workloads that demand deterministic, high-throughput inter-node communication with minimal latency variance.

Ideal for

• Direct switch-to-switch fabric uplinks in 200G HDR InfiniBand clusters supporting distributed deep learning model training
• GPU-to-GPU interconnect bridging within AI accelerator pods requiring sub-microsecond latency and guaranteed bandwidth
• High-performance computing (HPC) cluster fabric builds leveraging 200GbE Ethernet for scientific simulation and molecular modeling
• Data center spine-leaf topology connections in AI inference serving infrastructure with dynamic load balancing
• Backup fabric redundancy loops in mission-critical financial modeling and real-time risk analytics platforms
• Research institution fabric expansion for multi-petabyte distributed storage systems with concurrent high-bandwidth access
