NVIDIA 200G QSFP56 Passive DAC Cable 20m MMF MPO12

For data centers that demand uncompromising signal integrity over longer reaches, this 20-meter passive Direct Attach Copper (DAC) cable from NVIDIA delivers 200Gb/s throughput with a QSFP56 connector on each end. Unlike active optical cables that require power-hungry transceivers, the passive design draws less than 0.5W per end, cutting both energy costs and heat buildup in high-density racks. The 24 AWG conductors and 100 Ohm differential impedance ensure clean, low-latency transmission for InfiniBand HDR and 200GbE Ethernet fabrics.

Highlights

• 200 Gb/s aggregate data rate for bandwidth-hungry workloads
• QSFP56 to QSFP56 connectors, compatible with NVIDIA Mellanox ConnectX-6/7 NICs and Quantum/Spectrum switches
• Passive copper construction: no external power, minimal latency, and high reliability
• 20-meter reach for flexible rack-to-rack or row-to-row cabling
• PVC jacket in black for durability and easy identification
• Supports InfiniBand HDR and Ethernet 200GbE protocols

In daily use

Deploy this cable in high-performance computing clusters, enterprise core networks, or AI training pods where every microsecond counts. The passive design eliminates the need for optical transceivers, reducing failure points and total cost of ownership. With an operating temperature range of 0°C to 70°C, it thrives in both cooled data halls and warmer edge environments. The 20-meter length gives you the freedom to connect devices across adjacent cabinets without signal degradation.
