The equip 119452 is Active Optical Cables (AOC) are fiber optic cables that use electrical-to-optical conversion circuitry to transmit signals over longer distances with less signal loss and electromagnetic interference compared to traditional copper cables.HDMI 2.1 Active Optical Cable combines the advantages of both technologies to provide high-speed, high-bandwidth, and reliable connectivity for advanced audio and video applications. These cables use fiber optic technology to transmit signals over longer distances without any signal degradation or loss.Ideal for applications such as home theaters, conference rooms, classrooms, and digital signage installations where long-distance HDMI connectivity is required. These cables are also thinner, lighter, and more flexible than traditional copper cables, making them easier to install and manage.By supporting a maximum bandwidth of 48 Gbps, content up to 8K Ultra HD (7680 x 4320 @ 60 Hz) resolution can be displayed.
