BlueLAN NVIDIA Compatible 400G QSFP-DD Breakout DAC Cable MCP7F60-W003R26-BL, 2m AWG26

Data center engineers deploying NVIDIA high-performance computing clusters need reliable, high-density interconnects that can handle 400G traffic without adding latency or power draw. The BlueLAN MCP7F60-W003R26-BL is a 2-meter passive Direct Attach Copper (DAC) breakout cable that connects a 400G QSFP-DD port to multiple lower-speed interfaces, enabling flexible topologies in spine-leaf architectures. Its AWG26 copper conductors deliver a cost-effective, low-power alternative to optical modules for short-reach links.

Why choose it

This cable eliminates the need for expensive optical transceivers on short runs, reducing both capital and operational expenses. Its passive design consumes no power and generates no heat, improving overall rack efficiency. The QSFP-DD form factor doubles port density compared to QSFP28, maximizing switch faceplate utilization.

Ideal use cases

• Connecting NVIDIA switches to servers or storage in HPC clusters
• Building 400G-to-100G or 400G-to-50G breakout links in data centers
• High-density top-of-rack to end-of-row cabling

Good to know

The cable is hot-pluggable and operates at 3.3V, ensuring seamless integration with compatible NVIDIA equipment. As a passive copper assembly, it is best suited for distances up to 2 meters where signal integrity is maintained without active components.
