The NVIDIA/Mellanox MFA7U10-H003 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 centers, 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.
