InLine HDMI AOC Cable Ultra High Speed HDMI Cable 8K4K 70m

The InLine HDMI AOC Cable Ultra High Speed HDMI Cable 8K4K 70m is a 70-metre active optical HDMI cable designed for long-distance transmission of high-resolution video and high-quality audio. Compliant with the HDMI 2.1 specification, the cable supports a 48 Gbit/s data rate, enabling 8K at up to 60 Hz or 4K at up to 120 Hz, and includes Enhanced Audio Return Channel (eARC) support. The hybrid design combines copper conductors and optical fibres to provide reliable signal integrity over extended lengths while keeping the cable flexible and lightweight. Gold-plated HDMI Type A connectors and a black jacket complete the physical design for durable, low-loss connections.

Advantages

The active optical construction reduces signal attenuation and susceptibility to electromagnetic interference compared with long runs of pure copper, while remaining more robust and compatible than purely optical assemblies. Support for HDMI 2.1 features and a 48 Gbit/s bandwidth enables high-frame-rate 4K and native 8K video with low latency, and eARC allows transmission of lossless, high-resolution audio formats. Gold-plated contacts improve conductivity and corrosion resistance to maintain reliable connections in home cinema, professional and commercial installations.

Suitable for

• Home cinema installations connecting TVs, projectors and AV receivers over long distances
• Gaming setups requiring high frame rates and low latency for consoles and PCs
• Professional video editing and post-production where real-time 4K/8K playback is needed
• Conference rooms, digital signage and event AV where long cable runs are required
• Streaming devices and media players that deliver high-resolution content

How to use

Connect one HDMI Type A plug to the source device (for example a media player, game console or PC) and the other HDMI Type A plug to the display device (TV, projector or AV receiver). Ensure both devices support the desired HDMI 2.1 features and set the output resolution and refresh rate in the source device settings. Route the cable avoiding sharp bends and kinks to preserve the optical fibres inside; maintain gentle curves and secure the cable with appropriate clips or ties where necessary. No external power supply is required for normal operation; any active electronics are powered through the HDMI interface.

Usage recommendations

For best results, verify display and source compatibility with HDMI 2.1 and set the correct resolution and refresh rate in device menus. Avoid tight bending radii and protect connector ends from dust. When installing in permanent or public installations, use cable clips or conduit to prevent physical damage and limit exposure to direct sunlight or excessive moisture.
