BlueLAN Compatible NVIDIA MCP7F80-W01AR30-NV Passive Breakout DAC Cable, QSFP-DD to 8x SFP56, 400GBASE-CR8 to 8x 50GBASE-CR, 1m, 26 AWG, Black

The BlueLAN MCP7F80-W01AR30-BL is a high-performance passive breakout Direct Attach Copper (DAC) cable designed for data center and high-performance computing environments. It provides a reliable and cost-effective solution for connecting 400G QSFP-DD ports to eight 50G SFP56 ports, enabling seamless network upgrades and high-density interconnects.

Advantages

This breakout cable offers significant advantages over traditional optical transceivers and fiber cabling. It consumes less than 0.5W per end, reducing overall power consumption in the network. The passive design ensures zero latency and high signal integrity, while the 26 AWG construction provides flexibility and durability. Hot-pluggable QSFP-DD and SFP56 connectors simplify installation and maintenance.

Suitable for

• Data center spine-leaf architectures
