10m (33ft) NVIDIA/Mellanox MFA7U10-H010 Compatible 400G OSFP 8 x 50G PAM4 IHS/Finned Top to 2 x 200G QSFP56 4 x 50G PAM4 InfiniBand HDR Active Optical Breakout Cable

The NVIDIA/Mellanox MFA7U10-H010 is an 400Gb/s twin-port OSFP to 2x200Gb/s twin-port QSFP56 InfiniBand HDR Active Optical splitter Cable. Using the Octal Small Formfactor Plug (OSFP) and Quad Small Form Factor Pluggable 56 (QSFP56), this configuration contains eight high-speed electrical copper pairs, each operating at data rates of up to 50Gb/s. This cable is compliant with OSFP Rev. 5.0 and IEEE 802.3cd standards. AOCs enable higher port bandwidth, density and configurability at a low cost, and reduced power requirement in the data centres, used extensively in cloud and supercomputers. Additionally, AOCs are widely employed for connecting NVIDIA GPU-based systems to InfiniBand networks and InfiniBand storage fabrics. AOC cables offer the low-cost, high-value proposition and increased reliability over connectorized transceivers. They are lighter, more flexible, allow greater airflow, and support longer distances when compared with DAC cables.
Note："Finned-top" transceivers are now called "Integrated Heat Sink" (IHS) as the cooling fins are integrated into the OSFP connector metal top. Commonly used in air-cooled switches. "Flat-top" transceivers are now called "Riding Heat Sink" (RHS) as the cooling fins ride on top of the network card or systems internal cages. This is used for both air-cooled and liquid-cooled applications for DGX, ConnectX-7 and BlueField-3 DPUS.
