The J-Tech Digital JTECH-FCAB100 Fiber Optic HDMI cable is designed for long-distance data transmission with no signal loss. Using optical fiber rather than copper wire as the high-speed transmission medium, the JTECH-FCAB100 can flawlessly transmit 4K@60Hz video signals with no video or audio delay. Compared with traditional copper wire cables, JTECH-FCAB100 is a slimmer and thinner cable that transmits more efficiently without any need for external power, making it the ultimate plug and plug component in your entertainment system. Since the video is sent using light pulses, the cable provides higher immunity to EMI or RFI interference and there is less chance of video dropouts due to environmental electromagnetic noise.
