ACT 40 meters HDMI Premium High Speed 4K Active Optical Cable v2.0 LSZH HDMI-A male - HDMI-A male

The ACT 40 meters HDMI Premium High Speed 4K Active Optical Cable v2.0 LSZH (HDMI-A male to HDMI-A male) combines copper and fiber to transmit 4K@60Hz video and multi-channel audio over long distances up to 40 meters without data loss. The cable is fully shielded and uses a Low Smoke Zero Halogen jacket, making it suitable for installations where interference and fire-safety considerations matter. It supports HDR, CEC, HDCP 2.2, EDID, HEC, ARC, Dolby TrueHD and DTS-HD Master Audio for reliable performance in professional and sensitive environments.

Advantages

This Active Optical Cable provides lossless transmission over long runs by combining copper conductors and optical fiber, with an 18 Gbit/s bandwidth that handles 4K (3840x2160) at 60Hz with 4:4:4 chroma. The cable is fully shielded (aluminium foil and copper-encased connector chipset) and includes Kevlar protection for the fiber, reducing RFI/EMI and improving durability. Its LSZH jacket lowers the risk of toxic gas release in case of fire. Connectors are marked for easy identification of source and display ends, and the cable requires no external power.

Suitable for

• Medical imaging systems and diagnostic displays where low interference is essential
• Marine and nautical installations requiring durable long-reach cabling
• Data center and server room AV links with fire-safety requirements
• Large meeting rooms, lecture halls and corporate AV systems for 4K presentations

When it may not be suitable

This cable is designed for long-distance, high-resolution HDMI connections; it may be unnecessary for short runs where a standard passive HDMI cable suffices. It supports HDMI 2.0 features up to 18 Gbit/s but does not provide bandwidth for HDMI 2.1 features such as 8K, 4K at higher refresh rates beyond 60Hz, or variable refresh-rate gaming modes requiring greater throughput.

How to use

Identify the marked source and display connectors and plug the HDMI-A male ends into the corresponding HDMI ports on your source device and display. The cable requires no external power; once connected, configure the source and display settings to 4K@60Hz and enable HDR or audio formats as supported by your devices. For best results, avoid sharp bends and protect the cable from mechanical stress; route it according to installation standards for long-reach AV cabling.

What to consider before purchase

• Confirm that both source and display support HDMI 2.0 and the required audio/video formats
• Check that 40 m is an appropriate length for your installation and routing path
• Ensure you do not require HDMI 2.1 features such as 8K or higher-bandwidth gaming modes
• Verify connector type (HDMI Type A) matches your equipment

Usage recommendations

For installations in sensitive or safety-critical environments, keep the cable run away from high-power electrical equipment where possible, maintain gentle bend radii, and use the connector markings to ensure correct orientation between source and display. If you need longer runs than 40 m, select the appropriate length in the ACT AOC range that supports up to 100 m.
