The TL-FO2-HDC2 transmits an uncompressed 4K60 4:4:4 HDR stream up to 300m (1,000 ft.) over single mode or multimode fiber optic cable. The extender set supports HDMI 2.0, HDCP 2.2, HDR, multichannel audio, audio return channel (ARC), bi-directional IR, and bi-directional RS232 signals, and signal transmission is completely immune to EM and RF interference, an issue which limits traditional twisted pair products.
