InLine HDMI AOC Cable 17920X Ultra High Speed 8K, Active Optical, 20 m

InLine HDMI AOC Cable 17920X Ultra High Speed 8K, Active Optical, 20 m is an active optical HDMI cable designed for reliable long-distance transmission of high-resolution video and audio. The cable supports Ultra High Speed 8K signals over a 20 m run, using optical fibers to reduce attenuation and electromagnetic interference compared with traditional copper HDMI cables. Its construction and HDMI 2.1 feature set make it suitable for installations that require consistent 8K/4K performance across greater distances.

Advantages

The active optical design ensures minimal signal degradation over 20 meters and provides immunity to electromagnetic interference, improving stability in environments with multiple electronic devices. Support for Ultra High Speed 8K bandwidth enables transmission of high-resolution video and multi-channel audio with features such as higher refresh rates and HDR compatibility. The cable is lightweight and flexible compared to equivalent copper cables, which simplifies routing and handling in professional AV and home theater installations.

Suitable for

• Home theater setups requiring 8K or high-bandwidth 4K connections over long distances
• Professional AV installations in conference rooms, lecture halls, and control rooms
• Gaming systems and consoles that demand high refresh rates and low signal loss
• Video production and post-production workflows needing reliable long run HDMI links

Key specifications

How to use

Connect one end of the InLine HDMI AOC cable to the HDMI output of the source device (such as a Blu-ray player, gaming console, PC graphics output or AV receiver) and the other end to the HDMI input of the display or receiver. Ensure both connected devices support the desired resolution and refresh rate and that any required HDMI settings (e.g., HDCP, HDR, deep color) are enabled in device menus. The cable is directional only if indicated by manufacturer markings; if video does not appear, try reversing the cable orientation. Avoid sharp bends and excessive twisting near the connectors to preserve the integrity of the optical fibers.

Usage recommendations

For optimal performance, use the cable with devices that support HDMI Ultra High Speed features and verify HDMI settings on both source and display. Route the cable with gentle curves and secure it to avoid strain at connector ends. Keep the cable away from heat sources and sharp edges. If using in a professional installation, test the full resolution and audio formats before final installation to confirm compatibility.
