The Philips SWR3019W/93 is an AOC (Active Optical Cable) Fiber Optic HDMI Cable designed for high-resolution, long-distance video and audio transmission. Unlike standard copper HDMI cables, which suffer from signal degradation over long distances, AOC technology uses optical fiber core lines to transmit 4K signals smoothly over extended lengths (up to 100 meters) without signal loss or electromagnetic interference.
