Introduction to 200G QSFP28-DD AOC

Active Optical Cable (AOC) Overview

Active Optical Cable (AOC) is a type of cabling technology that utilizes optical fiber, electrical transceivers, and optical transmitters and receivers to improve cable performance. Traditional copper cables are replaced with high-speed optical fibers in AOCs, enabling data to be transmitted over longer distances with less loss and interference.

Advantages of Active Optical Cable

AOCs offer several significant advantages over conventional copper cables. They are lighter and thinner, which makes them easier to install and manage in data centers. AOCs are immune to electromagnetic interference (EMI), ensuring stable and reliable data transmission. They also support higher data rates over long distances, making them ideal for high-bandwidth applications.

Applications of Active Optical Cable

Active Optical Cables find extensive use in various high-speed network applications. They are frequently deployed in data centers, high-performance computing networks, enterprise network storage systems, and telecommunications. With the rapid development of cloud computing and big data, the demand for AOCs in high-speed, high-capacity data transmission scenarios is expected to rise significantly.
