MCP7Y00-N002 NVIDIA/Mellanox Compatible 800Gb/s OSFP to 2x400Gb/s OSFP Passive Breakout DAC Cable - 2m
Warranty: Lifetime
Quick answer: The MCP7Y00-N002 NVIDIA/Mellanox-compatible cable is a 2-meter passive copper breakout (splitter) DAC that splits one 800G twin-port OSFP port into two 400G OSFP connections, for linking an NDR InfiniBand switch such as the Quantum-2 QM9700 to two 400G NDR ports, such as ConnectX-7 OSFP adapters, in the same or an adjacent rack. It is coded to work in NVIDIA equipment that calls for MCP7Y00-N002. Resilient Tec sells it new, with a lifetime warranty and free US shipping from Knoxville, TN.
NVIDIA/Mellanox MCP7Y00-N002 Compatible 800Gb/s Twin-Port OSFP to 2x400Gb/s OSFP Passive Breakout DAC Cable - 2 Meters
This third-party passive breakout DAC cable is fully compatible with NVIDIA/Mellanox MCP7Y00-N002, delivering an 800Gb/s twin-port OSFP connection split to two independent 400Gb/s OSFP ports. Engineered for InfiniBand NDR environments in cutting-edge AI supercomputers, HPC clusters, and hyperscale data centers.
Compliant with MSA standards, it supports massive bandwidth (800G total, 2x400G PAM4) with ultra-low power and latency. Backed by our lifetime warranty and rigorous testing—save significantly vs. genuine OEM.
Key Features
- Extreme Cost Savings: Affordable compatible for NDR deployments—scale AI superclusters without premium pricing.
- Plug-and-Play: Hot-pluggable OSFP connectors (finned/flat top variants) with pre-programmed EEPROM for seamless NVIDIA compatibility.
- Ultra-Low Power & Latency: Passive design (<0.5W total) for dense, efficient racks in power-hungry AI environments.
- Lifetime Warranty: Fully tested.
- Use Cases: Splitter for multi-node GPU interconnects in NDR switches (e.g., QM9700 series), enabling 800G to 400G fan-out.
Technical Specifications
- Data Rate: 800Gbps total (twin-port NDR InfiniBand, split to 2x400Gbps, PAM4)

Frequently Asked Questions
What does each end plug into?
The single 800G end goes into a twin-port OSFP cage on the switch. Each 400G leg goes into a 400G OSFP port, such as a ConnectX-7 OSFP adapter.
MCP7Y00-N002 or MCP7Y50-N001: which do I need?
The MCP7Y00-N002 splits one 800G switch port into two 400G links. The MCP7Y50-N001 splits it into four 200G 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 couple of meters, 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.
