The 400G QSFP-DD Active Optical Cable (AOC) is a high-performance interconnect solution designed for high-speed data transmission over longer distances in modern data centers and enterprise networks. Featuring QSFP-DD connectors on both ends, it supports data rates of 400 Gbps through eight 50 Gbps lanes, making it ideal for applications such as cloud computing, artificial intelligence, and high-bandwidth networking. Unlike passive cables, this AOC integrates active optical components to enhance signal integrity and extend transmission distances beyond the limitations of copper cables, reaching up to 50m. Its lightweight, low-power design minimizes electromagnetic interference (EMI) while delivering superior reliability and efficiency in dense networking environments. Compliant with QSFP-DD MSA and IEEE 802.3cd standards, the 400G QSFP-DD AOC offers a plug-and-play solution for seamless deployment. It combines flexibility, scalability, and performance, making it an excellent choice for organizations looking to optimize their high-speed networking infrastructure.
