The 400G QSFP-DD to 2x 200G QSFP56 breakout active optical cables operate over multi-mode fibers (MMF). This breakout cable is compliant with IEEE 802.3, QSFP-DD MSA, SFF-8024, SFF-8679, SFF-8665, OIF-CEI-04.0, and CMIS 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: The FS P/N is changed from QDD-2Q56AO03 to QDD-400G-2QAO03, but the product is the same. Only the FS P/N has been changed.
