MCP7H50-H001R30 Compatible 200G QSFP56 to 2x100G QSFP56 Breakout DAC Cable - 1M | Mellanox / NVIDIA
Warranty: Lifetime
200G QSFP56 to 2x100G QSFP56 Passive Breakout DAC Cable — Pre-Tested for Mellanox / NVIDIA
The MCP7H50-H001R30 is a 200G QSFP56 to 2x100G QSFP56 passive breakout DAC cable engineered for high-density spine-leaf networks, AI/HPC clusters, and hyperscale data centers. Every unit is pre-programmed with EEPROM compatibility data and validated before shipment — so it works the moment you plug it in.
Will This Cable Work With My Switch?
This cable is pre-coded for seamless plug-and-play recognition on:
- NVIDIA Quantum HDR InfiniBand switches (e.g., QM8700 / QM8790) on the 200G end
- ConnectX-6 HDR100 adapters (or HDR100 split ports) on the two 100G ends
- Running Ethernet instead? A 200GbE Spectrum port split to 2x100GbE uses the MCP7H50-V family — ask us

DAC vs AOC vs Transceivers — Which Should You Use?
| Feature | DAC (This Cable) | AOC | Transceivers |
|---|---|---|---|
| Cost | ✅ Lowest | Medium | Highest |
| Latency | ✅ Ultra-low (passive) | Low | Higher |
| Power Draw | ✅ 0W (passive) | Medium | High |
| Best Distance | Up to 1 meter | Up to 100m | Long-range |
Best for: intra-rack and top-of-rack breakout connections where cost, latency, and power efficiency matter.
Ideal Use Cases
- GPU cluster interconnects for AI training and inference workloads
- High-throughput storage networking (NVMe over Fabric, RDMA)
- Spine-to-leaf breakout in hyperscale and enterprise data centers
- HDR InfiniBand environments requiring 200Gb/s port splitting
Common Mistakes This Cable Prevents
- Overspending on optics when passive DAC is sufficient for 1-meter runs
- Compatibility failures from OEM-locked or uncoded cables
- Latency overhead introduced by active components in short-distance links

MCP7H50 Cross-Reference: HDR vs Ethernet, and Which Length
Short answer: MCP7H50-H001R30 is a 1m passive splitter. One end is a 200Gb/s HDR QSFP56 plug for the switch, and the other end is two 100Gb/s HDR100 QSFP56 plugs, typically into two ConnectX-6 HDR100 adapters. The "H" means InfiniBand. For a 200GbE Ethernet switch port split to 2×100GbE, the matching NVIDIA family is MCP7H50-VxxxRyy.
| Part number | Length / gauge | At Resilient Tec |
|---|---|---|
| MCP7H50-H001R30 | 1m · 30AWG | This listing |
| MCP7H50-H01AR30 | 1.5m · 30AWG | Ask us |
| MCP7H50-H002R26 | 2m · 26AWG (thicker, longest passive length NVIDIA offers) | In stock |
Need more than 2m? Passive HDR splitters stop at 2m. Beyond that, use an active optical splitter or separate optics. Contact us and we'll spec it.
