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.
