HDMI Active Optical Cable (AOC) is a type of cable that is used to transmit high-definition audio and video signals between two devices. The AOC features an active optical fiber core with an HDMI connector at each end and is designed to be flexible and more durable than traditional copper HDMI cables or cords.

AOCs use fiber optics to reduce size and weight while maintaining signal quality. This makes them ideal for use in confined spaces or in applications where a high degree of durability is needed.
