HDMI Active Optical Cable (HDMI AOC) is basically the technology where HDMI signal is transmitted over a fiber optic cable instead of a regular copper HDMI cable, so it is transmitted more reliably and with higher resolution. The cable features a mixture of both fiber and copper wire, which provides a thinner core than regular copper HDMI cables and makes it perfect for installation in narrow spaces. The fiber composition also makes the cable immune to EMI (electromagnetic interference) and RFI (radio frequency interference).
