WHY CHOOSE THIS PRODUCT?

• MCP7Y70-H001 is a practical choice when a compatible NVIDIA/Mellanox HDR fabric requires one 400Gb/s OSFP connection to break out into four 100Gb/s QSFP56 links. Its 1m passive copper design is particularly suited to dense rack deployments where short, direct connections can simplify physical infrastructure. Compared with the same MCP7Y70 family, this model provides the shortest documented 1m option, while 1.5m and 2m versions support different rack-routing requirements. For procurement teams, selecting the exact cable length and connector topology helps avoid unnecessary cabling, simplifies replacement matching, and supports consistent expansion of existing HDR InfiniBand environments.
