HDMI 2.1 Active Optical Cable. Fiber-optic technology allows Active Optical Cables (AOC) to transmit ultra-high-bandwidth data signals over distances that copper cannot. So what are the advantages of running a fiber optical cable over a copper cable? Fiber cables are much stronger than copper cables and also a lot more flexible. Fiber cables handle weather conditions better than a copper cable ensuring you dont have data stall issues which can cause problems when sending 4K & 8K signals over long distances. Overall a fiber able is more reliable than a copper cable especially over long distances Important Notes: - This cable is not a bi-directional. The “Source” HDMI connector is for source devices (such as a PC, Blu-ray player, game console), and “Display” HDMI connector for monitors, TVs, projectors, Home Theater.
