200G QSFP56 to QSFP56 DAC Cable (0.5M) — NVIDIA DGX Spark, 200GbE & InfiniBand HDR (QSFP56-200G-CU50CM)

This 200G QSFP56 to QSFP56 passive direct-attach copper (DAC) cable provides a reliable short-distance connection for high-speed network equipment. It supports transmission speeds up to 200Gbps and is designed for 200GbE and InfiniBand HDR applications.

The compact 0.5M / 1.64ft length is ideal for connecting adjacent switches, servers, storage devices and network adapters within the same rack. Its passive twinax copper construction delivers low latency, low power consumption and stable signal integrity, making it well suited to data centers, AI computing systems and HPC clusters.

• Compatible with NVIDIA DGX Spark — connect two DGX Spark systems through their QSFP network ports for high-speed 200GbE direct communication, AI workload sharing, model processing and desktop cluster applications.
• 200G QSFP56 Passive DAC — delivers up to 200Gbps through four 50G PAM4 lanes; the passive design provides a stable, low-latency link without optical transceivers or an external power supply.
• 200GbE & InfiniBand HDR support — designed for compatible 200G Ethernet and InfiniBand HDR equipment, including ConnectX network adapters, servers, switches, storage systems and HPC platforms.
• 0.5m / 1.64ft 30AWG Twinax — short copper cable ideal for connecting adjacent desktop systems or equipment within the same rack while reducing excess cable length.
• Check compatibility before purchase — QSFP56-to-QSFP56 configuration; compatibility depends on the equipment port, firmware and cable coding. This is a passive copper DAC cable, not an optical cable, transceiver or breakout cable.
