How Does an Optical HDMI Cable Work?
An optical HDMI cable uses fiber optic technology to transmit high-definition audio and video signals over long distances. Unlike its counterpart, the conventional copper HDMI cable uses electrical signals. A fiber optic HDMI cable has specialized transmitters that change electrical signals to light. These light signals travel down and through the optical fibers and get converted back to electrical signals by the receivers on the other end. This ensures that there is virtually no signal loss or resistance, making it easier for tasks that have long cable runs or require no interference to be performed with superior quality.
