Greatly upgraded for long-distance audio & video transmission scenarios such as embedded home wiring, engineering cabling, conference rooms and large exhibition screens! AOC Active Optical HDMI Cable breaks through the transmission distance limits of traditional copper cables. Specially engineered for stable ultra-long-distance transmission up to 10m and 20m, it perfectly resolves common drawbacks of ordinary long copper cables including severe signal attenuation, screen flickering, disconnection and stuttering, making it the top choice for professional high-definition wiring projects.This optical fiber cable features standard HDMI Male to Male connectors with full-spec HDMI 2.0 high-speed performance. It supports a massive 18Gbps bandwidth, ARC (Audio Return Channel) and High-Speed Ethernet, delivering stable 4K@60Hz Ultra HD visuals. It accurately captures and processes every signal source for precise, distortion-free image transmission. Equipped with Dynamic HDR imaging and 12-bit high color depth processing, it comprehensively optimizes picture performance with wider color gamut, higher brightness and finer light-dark contrast. The layered light and shadow create vivid, lifelike colors with crisp, delicate details for a rich, immersive viewing experience. It is backward compatible with all older HDMI versions and fits most mainstream audio-visual devices.Adopting photoelectric conversion fiber transmission technology, it transmits optical signals instead of electrical signals to fundamentally eliminate electromagnetic interference and maintain pure, steady signals over long distances. The cable is fitted with corrosion-resistant gold-plated connectors and sturdy aluminum alloy housings to greatly boost transmission stability, ensuring tight, secure connections free from looseness and poor contact. Dual-layer shielding composed of aluminum foil and dense braided mesh fully blocks external EMI and RFI, completely avoiding screen flicker, stuttering, pixelation and signal dropout.The user-friendly lock-free design delivers effortless plug-and-play operation. No buttons need pressing during insertion and removal for smooth, labor-free connection, speeding up daily installation and wiring while reducing interface wear to extend the cable’s service life, balancing practicality and durability.This DP 1.4 high-definition cable is tailor-made for audio-visual enthusiasts and gamers with broad compatibility. It works seamlessly with all devices equipped with standard DP 1.4 ports, including laptops, desktops, discrete graphics cards and HD monitors, allowing you to easily build professional setups for high-definition media, competitive gaming and multi-screen office work.
