ACT HDMI Active Optical Cable 70 m — Premium High Speed 4K v2.0, HDMI-A male to HDMI-A male, 18 Gbit/s, LSZH, Black

The ACT HDMI Active Optical Cable 70 m is a premium high-speed HDMI v2.0 cable designed for long-distance AV connections. Combining copper and fiber, the active optical cable transmits 4K video (3840x2160) at 60 Hz with an 18 Gbit/s bandwidth while maintaining signal integrity over 70 meters. The LSZH jacket and full shielding make the cable suitable for installations where safety and low electromagnetic interference are important.

Advantages

The cable delivers stable 4K@60Hz 4:4:4 performance with support for HDR, CEC, HDCP 2.2, EDID, HEC, ARC and multi-channel audio including Dolby TrueHD and DTS-HD Master Audio. Its active optical design of copper and fiber enables long-distance transmission without external power, and comprehensive shielding—Kevlar-protected fiber with aluminium foil and copper-encased connector chipset—reduces RFI/EMI. The LSZH outer jacket reduces toxic gas emissions in the event of fire, and connector markings help quickly identify source and display ends.

Suitable for

• Professional AV installations and conference rooms where long cable runs are required
• Medical imaging and radiology systems that require high-resolution images and low interference
• Marine and nautical applications needing durable, long-distance signal links
• Data centres and public buildings where LSZH cabling is preferred for safety
• Home theaters and classrooms requiring clear 4K video and multi-channel audio over long distances

When it may not be suitable

This cable is an Active Optical Cable optimized for long runs up to 70 metres; it may be unnecessary for short domestic connections where standard passive HDMI leads suffice. It also does not include identifiers or adapter functionality for non-HDMI interfaces, so additional adapters may be required for other connector types.

How to use

Identify the source and display ends using the connector markings and plug the HDMI Type A male connectors into the source device (for example a media player or computer) and the display (TV, monitor, or projector). Ensure both devices support HDMI 2.0 features you intend to use (HDR, HDCP 2.2). The cable requires no external power—connect and use. For best results, avoid sharp bends and protect the cable from physical damage; route it according to installation standards for long cable runs.

What to consider before purchase

• Confirm that both source and display support HDMI 2.0 features (4K@60Hz, HDR, HDCP 2.2) you need
• Choose cable length appropriate for the installation; this product is 70 m
• Consider LSZH requirement in the installation environment (public buildings, data centres, marine)
• Ensure HDMI Type A to Type A is compatible with your devices or whether adapters are needed

Usage recommendations

The cable performs best when routed without tight bends, kept away from strong mechanical stress, and installed with proper strain relief. Use the connector markings to avoid reversing source and display ends and verify device HDMI settings (resolution, HDR, HDCP) before testing the signal.
