The 400G OSFP to 2x 200G QSFP56 breakout active optical cables operate over multi-mode fibers (MMF). This breakout cable is compliant with IEEE 802.3cd, OSFP Rev.5.0, SFF-8679, SFF-8661, SFF-8636, and CMIS Rev.4.0.
Thin and lightweight AOC cables simplify cable management, enabling an efficient system airflow, which is critical in high-density racks. It is used extensively in cloud and supercomputers due to its low cost, high-value proposition, and increased reliability.
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.
