A fiber optic HDMI cable is a cable using optical fiber as the transmission medium,the principle of the cable is to integrate the photoelectric conversion line at the hdmi interface and use the fiber optic as the transmission medium material; during the transmission process, the hdmi optical fiber transmitting end converts the hdmi signal into an optical signal and transmits it to the hdmi fiber optic through the optical fiber medium line receiving end, the receiving end then converts the optical signal into a lossless hdmi signal and outputs it to the display device.
