MCP7Y50-N001 Compatible 800G OSFP to 4x200G OSFP Breakout DAC Cable - 1M | NVIDIA / Mellanox
Warranty: Lifetime
Quick answer: The MCP7Y50-N001 NVIDIA/Mellanox-compatible cable is a 1-meter passive copper breakout (splitter) DAC that splits one 800G twin-port OSFP port into four 200G OSFP connections, for linking an NDR InfiniBand switch such as the Quantum-2 QM9700 to four 200G adapter ports in the same rack. It is coded to work in NVIDIA equipment that calls for MCP7Y50-N001. Resilient Tec sells it new, with a lifetime warranty and free US shipping from Knoxville, TN.
800G OSFP to 4x200G OSFP Passive Breakout DAC Cable — Pre-Tested for NVIDIA / Mellanox
The MCP7Y50-N001 is an 800G OSFP to 4x200G OSFP passive breakout DAC cable built for next-generation AI clusters, hyperscale data centers, and NDR InfiniBand fabrics. It delivers 800Gbps aggregate throughput by splitting a single 800G OSFP port into four independent 200G OSFP connections — with zero active components and zero power draw. Every unit is pre-programmed with EEPROM compatibility data and validated before shipment.
Will This Cable Work With My Platform?
Pre-coded for seamless plug-and-play recognition on:
- NVIDIA Quantum-2 / NDR InfiniBand switches (QM9700 series and compatible)
- NVIDIA DGX / HGX systems and GPU-to-switch interconnects
- Any OSFP MSA-compliant platform supporting NDR InfiniBand
Not sure if this matches your exact setup? Contact us before you buy — our engineers will confirm compatibility for free.
Best for: GPU-to-switch, switch-to-switch, and top-of-rack breakout connections in high-density AI and HPC environments.
Designed for AI & HPC Infrastructure
- GPU cluster interconnects — spine-to-GPU or switch-to-DGX/HGX connections
- NDR InfiniBand fabrics — 800G port breakout to 4x200G NDR endpoints
- AI training and inference at scale — maximize throughput, minimize latency between nodes
- Hyperscale data center leaf-spine — high-density 800G port utilization
- High-throughput storage — NVMe over Fabric, GPUDirect Storage at 200G per lane
Common Mistakes This Cable Prevents
- Buying AOC when DAC is sufficient — for 1-meter runs, passive DAC is lower cost, lower latency, and zero power
- OEM-locked cables causing recognition failures — our EEPROM pre-coding eliminates firmware rejection
- Wrong connector type — OSFP and QSFP-DD are not the same; always verify your port type before ordering
- Latency spikes from active components — passive DAC has no signal processing, no added jitter

Frequently Asked Questions
What does each end plug into?
The single 800G end goes into a twin-port OSFP cage on the switch. Each of the four 200G legs goes into an OSFP port running at 200G, such as an NDR200 adapter port.
MCP7Y50-N001 or MCP7Y00-N002: which do I need?
The MCP7Y50-N001 splits one 800G switch port into four 200G links. The MCP7Y00-N002 splits it into two 400G links. Pick the one that matches the speed of the adapter ports on the other end.
Why a DAC instead of optics?
For in-rack runs of a meter or two, a passive DAC costs far less, draws no power and adds no optical latency. For longer runs between racks, use OSFP optics with fiber.
Compatible cable or genuine NVIDIA: what is the difference?
This is a new third-party cable programmed (coded) to be recognized by NVIDIA/Mellanox equipment that calls for this part number, at a fraction of the NVIDIA-branded price. Choose the genuine NVIDIA part only if your support contract or internal policy requires NVIDIA-branded parts.
What warranty and shipping come with it?
Resilient Tec's lifetime warranty. US standard shipping is free with no minimum, and orders typically arrive in 3 to 5 days.
