Brief Introduction
The Vchung 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.

 | Optical transceivers port(LC) For LC port, there are two types of single-fiber bidirectional optical transceivers (one LC connector) and dual-fiber unidirectional optical transceiver (two LC connectors). Single fiber bidirectional is used to send and receive signals in one fiber, and dual fiber unidirectional optical transceivers are used to one fiber to send signals and other fiber to receive signals. |
