MCP1650-V00AE30 QSFP/CX7 Cable — 200G QSFP56 Passive DAC, 0.5m – NVIDIA DGX Spark Compatible
Warranty: Lifetime
EEPROM Coded and Made in USA
NVIDIA DGX Spark compatible — 200G QSFP56 passive DAC cable
→ DGX Spark interconnect reference — approved part numbers, real-world throughput, and what to buy at two, three and four or more nodes.
Part Number: MCP1650-V00AE30 (NVIDIA / Mellanox equivalent)
Description: QSFP56 Passive Direct Attach Copper (DAC) cable, 200G-rated, 0.5m (1.6 ft)
The MCP1650-V00AE30 is a 0.5m passive direct-attach copper cable with QSFP56 connectors on both ends, rated for 200G. It is engineered to connect two NVIDIA DGX Spark systems directly through their ConnectX-7 QSFP ports — no switch, transceivers, or adapters required. Each ConnectX-7 QSFP port on the DGX Spark operates at up to 200 Gb/s, which this QSFP56 200G cable matches exactly, making it a viable, tried-and-tested lower-cost interconnect for stacking two units.
Because the NVIDIA GB10 reference design is shared across the ecosystem, the same ConnectX-7 200GbE port — and therefore this same cable — also works on the OEM GB10 systems (Dell Pro Max with GB10, HP ZGX Nano AI Station, and ASUS Ascent GX10). NVIDIA remains the primary platform; the others are cross-compatible because they use identical networking silicon.

Good to Know
- Connects two units directly — no switch, transceivers, or adapters required
- 0.5 m is ideal for two compact desktop units placed side by side
- Stacking is supported for 2 units at a time (no chaining 3+ in series over this port)
- The ConnectX-7 QSFP ports operate in Ethernet mode (with RoCE), not InfiniBand
- Also works across the wider GB10 ecosystem (Dell Pro Max with GB10, HP ZGX Nano AI Station, ASUS Ascent GX10), which share the same ConnectX-7 200GbE networking
- The port and cable are identical across brands, but the physical location and labeling of the ConnectX-7 port can differ by chassis — confirm the port location in your vendor manual before cabling
Quick Checklist — Is This the Right Cable?
You have two NVIDIA DGX Spark systems (or a GB10-based equivalent from Dell, HP, or ASUS). You want to link them directly through their ConnectX-7 QSFP ports. You want a proven, lower-cost 200G option that runs at the full 200 Gb/s the port supports. You need a 0.5 m passive copper cable with QSFP56 connectors on both ends.
