UGREEN HD178 (45508) 40M 4K Fiber Optic HDMI Cable

The UGREEN HD178 (45508) 40-Meter Active Optical Fiber (AOC) HDMI Cable represents the pinnacle of long-distance Ultra High Definition transmission technology. Spanning a massive 40 meters (131.2 feet), it converts electrical video signals into light pulses across 4-core optical fibers, delivering uncompressed 4K UHD @ 60Hz with zero latency, zero frame loss, and absolute immunity against electromagnetic noise.

True 4K@60Hz Visuals & 18Gbps Lossless Optical Speed

Traditional copper HDMI cables suffer severe signal attenuation and blackouts past 10 meters. By harnessing premium photoelectric conversion microchips, the UGREEN HD178 maintains full 18Gbps bandwidth across the entire 40-meter run. It supports breathtaking 3840 × 2160 resolution at 60 frames per second, 4:4:4 uncompressed chroma subsampling, and rich HDR10, producing vibrant color depth and deep black contrasts for high-end home theater projectors and commercial video walls.

Zero Electromagnetic Interference (Zero EMI/RFI)

Unlike conventional copper wiring that picks up electrical hum and interference from high-voltage AC cables, lighting ballasts, and office machinery, optical fibers are non-conductive to electromagnetic frequencies. This makes the UGREEN HD178 the ultimate solution for running through ceilings, cable conduits, and behind drywall in auditoriums, broadcast studios, medical visualization suites, and luxury villas.

Zinc-Alloy Shells & Ultra-Slim 4.8mm Profile

Engineered for rugged in-wall installations, both HDMI connectors are housed in precision-molded zinc and aluminum alloy shells that resist physical impacts and dissipate internal chip heat efficiently. Despite its extreme transmission range, the cable maintains a flexible, lightweight 4.8mm outer diameter, enabling effortless routing through narrow raceways and tight conduit corners. Note: As an Active Optical Cable, it is uni-directional; connect the "Source" plug to your player/PC and the "Display" plug to your TV or projector.

Key Highlights:

• Massive 40M Optical Range: Transmits 4K@60Hz video up to 40 meters without requiring external signal repeaters.
• Active Optical Fiber Core: 4-core fiber optics provide 100% immunity to EMI/RFI noise and zero signal attenuation.
• Uncompromised 18Gbps HDMI 2.0: Flawlessly streams 4K@60Hz, HDR10, 3D video, and HDCP 2.2 content.
• Cinema-Quality Audio: Passes Dolby Atmos, DTS:X, and ARC (Audio Return Channel) audio to soundbars and receivers.
• Heavy-Duty Metal Casings: Rugged aluminum alloy connector shells protect internal photoelectric conversion chips.
• Slim & Highly Flexible: Thin 4.8mm profile pulls easily through conduit pipes and drywall partitions.
