ACT 50 meters HDMI Premium High Speed 4K Active Optical Cable v2.0 LSZH HDMI-A male - HDMI-A male

The ACT 50 meters HDMI Premium High Speed 4K Active Optical Cable v2.0 LSZH (HDMI-A male to HDMI-A male) is an active optical cable engineered for long-distance 4K video and multichannel audio transmission. Combining copper and fiber, the cable carries 4K (3840x2160) at 60Hz with 18 Gbit/s bandwidth over distances up to 50 meters in this model, and is built with full shielding and a Low Smoke Zero Halogen jacket for use in sensitive or safety-conscious environments. The connectors are clearly marked to help identify source and display ends.

Advantages

This HDMI Active Optical Cable delivers high-resolution video and multichannel audio over a long distance without the need for external power. The cable features full shielding including Kevlar-protected fiber, aluminium foil and copper-encased chipset to minimize RFI/EMI, and a LSZH jacket that reduces toxic gas emission in case of fire. It supports HDR, CEC, HDCP 2.2, EDID, HEC, ARC, Dolby TrueHD and DTS-HD Master Audio, ensuring compatibility with professional AV setups.

Suitable for

• Medical imaging and radiology suites requiring low interference and high-resolution displays
• Marine and nautical installations where durable, long-reach connections are needed
• Data centers and equipment rooms where LSZH cabling is required for safety
• Large meeting rooms, lecture halls and corporate AV systems for 4K presentations

When it may not be suitable

This specific product is a 50 m active optical cable; it is not suitable if a shorter passive HDMI cable is preferred for simple consumer setups or if a different HDMI version (for example 2.1) and higher bandwidth than 18 Gbit/s are required. Devices that explicitly require passive-only copper connections or connectors other than HDMI Type A will not be compatible.

• Color: black

How to use

Identify the source and display ends using the connector markings, then insert the HDMI Type A male connectors into the HDMI output of your source device and the HDMI input of your display or receiver. No external power is required; the cable transmits signal and power for its internal electronics through the HDMI connections. Ensure both devices support HDMI 2.0 features (HDR, HDCP 2.2, etc.) to make full use of the cable's capabilities.

What to consider before purchase

• Confirm that source and display devices support HDMI 2.0 and the required audio/video formats
• Verify that 50 m cable length fits your installation; longer lengths are available if needed
• Check that HDMI Type A (standard) male connectors are compatible with your equipment
• Determine whether LSZH jacket is required by local safety regulations or installation environment

Usage recommendations

For stable 4K@60Hz performance, avoid tight bends and severe kinks in the cable; route the cable away from strong electromagnetic sources despite its shielding, and secure connectors to prevent strain on device ports.
