200G QSFP56 Passive DAC Cable 0.5m | DGX Spark Dual-System Interconnect | MCP1650-V00AE30 Compatible | Resilient Tec
Warranty: Lifetime
0.5m (1.6ft) 200G QSFP56 Passive Direct Attach Copper cable engineered for NVIDIA DGX Spark dual-system interconnect. Compatible with NVIDIA/Mellanox MCP1650-V00AE30. Connects two DGX Spark units via built-in ConnectX-7 200GbE ports. 4-channel PAM4 modulation, 30AWG twinax, under 0.1W power draw. Plug-and-play, no active components, no cooling required. Compliant with QSFP56 MSA, IEEE 802.3bj, IEEE 802.3cd, and RoHS. Ideal for AI inference clusters, edge HPC, and DGX Spark scale-out deployments.

Key Specifications
- Type: Passive Direct Attach Copper (DAC) Twinax cable (no active electronics — very low power and latency)
- Data Rate: 200 Gb/s (4 × 50 Gb/s PAM4 lanes)
- Connectors: QSFP56 to QSFP56
- Length: 0.5 m (≈1.6 ft / 19.7 inches)
- Wire Gauge: 30 AWG
- Jacket: LSZH (Low Smoke Zero Halogen)
- Pull Tab: Typically black
- Compliance: SFF-8665, RoHS, halogen-free
- Operating Temperature: 0°C to 70°C
- Power Consumption: Extremely low (≈0.1 W or less per end)
- Protocol Support: 200GbE Ethernet / RoCE (RDMA over Converged Ethernet) — validated for DGX Spark GPU-direct communication and multi-node AI workloads
- Equivalent NVIDIA/Mellanox Reference: Closely matches MCP1650-V00AE30 (0.5m 200GbE QSFP56 DAC)
- Connect two DGX Spark systems or "DGX Spark dual-system interconnect
- NVIDIA ConnectX-7 200GbE port (the built-in port people are plugging into)
- 0.5m is the correct/recommended length for DGX Spark
- Compatible OEM part: MCP1650-V00AE30 (the NVIDIA/Mellanox original) — people search for the OEM part and look for alternatives
- "Passive DAC, no power required, plug-and-play" — common DGX Spark setup
