Flawless 4K Over Long Distances Push your visual boundaries. The UGREEN HD178 Fiber Optic HDMI Cable is engineered to deliver pristine 4K@60Hz Ultra HD video and rich, uncompressed audio over a full 25-meter distance. Unlike traditional copper cables that can suffer from signal degradation at extended lengths, this Active Optical Cable (AOC) guarantees flawless, zero-latency transmission for professional home theaters, auditoriums, and complex AV setups.

Advanced Fiber Optic Technology Built for perfection. By utilizing a photoelectric conversion module and fiber optic cores, this cable transmits data at the speed of light. This completely eliminates electromagnetic interference (EMI) and ensures a stable 18Gbps bandwidth without the need for bulky external signal boosters or power supplies. It fully supports dynamic HDR, 3D video, and Audio Return Channel (ARC) for a deeply immersive cinematic experience.

Premium Aluminum Shell & Flexible Design Durability meets ease of installation. The robust aluminum alloy connectors rapidly dissipate heat and actively resist corrosion for a longer lifespan. Meanwhile, the specialized fiber optic core allows the cable to be significantly thinner, lighter, and more flexible than standard copper cables, making it much easier to route through walls, ceilings, and tight conduits.
