NVIDIA® MCP7F80-W0xxRyy DAC (Direct Attach Copper) splitter cables are a high speed, cost-effective 400GbE to 8 x 50GbE Ethernet connectivity solution, designed to meet the growing needs for higher bandwidth in data centers

The MCP7F80 cables provide connectivity between system units with QSFP-DD port on one side and up to eight different SFP56 ports on the other. The cable connects data signals from each of the 8 copper pairs on the QSFP-DD end to the single pair of each of the SFP56 ends. Each QSFP-DD/SFP56 port comprises an EEPROM providing product information, which can be read by the host system.

NVIDIA’s unique-quality cable solutions provide power-efficient connectivity for short distance interconnects, enabling higher port bandwidth, density and configurability at a low cost and reduced power requirement in the data centers. Rigorous cable production testing ensures best out-of-the-box installation experience, performance, and durability.
