Brief Introduction
The Vchung 400G QSFP-DD to 4x 100G QSFP56 breakout active optical cables are designed for use in 400 Gigabit Ethernet links over OM3 multimode fibers, each operating at data rates of up to 53.125Gbps per channel by PAM4 modulation. This breakout cable is compliant with IEEE 802.3cd, OIF-CEI, QSFP-DD MSA, QSFP-DD-CMIS, IEEE 802.3bs Annex120E SFF-8024, SFF-8679, SFF-8682 standards. 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. |
