AEC resets both signal loss and timing, delivering cleaner eye diagrams and supporting longer distances—typically up to 5–7 meters. With retimers and Forward Error Correction (FEC), AECs offer superior performance for demanding AI workloads. There are various connection solutions available for switching networks, such as optical modules + optical fibers, Active Optical Cables (AOC), and Direct Attach Cables (DAC). DAC can be further categorized into active ACC, AEC, and passive DAC. AOCs integrate optical transceivers and fiber optic cables into a single unit, enhancing signal quality and reliability. This guide provides a complete comparison of AOC vs DAC vs ACC vs AEC, helping you select the optimal interconnect for your AI workloads. 6T, supporting 100G and 200G per lane electrical and optical I/O on both the host and line side interfaces for AI infrastructure connectivity.
