## Long description

The ACT 25 meters HDMI Premium High Speed 4K Active Optical Cable v2.0 LSZH (HDMI-A male to HDMI-A male) is an active optical cable constructed from copper and fiber to transmit 4K video (3840x2160) at 60 Hz over long distances up to 100 meters without data loss. The cable features full shielding, a LSZH jacket, and a Kevlar-protected fiber core to deliver reliable video and audio performance for professional and sensitive environments. It supports HDR, HDCP 2.2, CEC, EDID, HEC, ARC, multi-channel audio, Dolby TrueHD and DTS-HD Master Audio.
Advantages
This active optical cable combines copper and fiber to maintain signal integrity over extended runs while requiring no external power. Full shielding (aluminium foil and copper-encased chipset) and low RFI/EMI make the cable suitable for interference-sensitive settings. The LSZH jacket reduces the risk of high concentrations of toxic gases in case of fire, and the Kevlar reinforcement increases durability in demanding installations. With an 18 Gbit/s bandwidth it reliably carries 4K@60Hz 4:4:4 video and high-resolution multi-channel audio.
Suitable for
Long-distance 4K video distribution in auditoriums, lecture halls and corporate meeting rooms
Medical imaging and diagnostic displays where low RFI/EMI is important
Data centers and server rooms requiring LSZH-rated cabling for safety
Marine and nautical installations needing durable, shielded cable runs
Home theatre or professional AV setups requiring 4K@60Hz over extended distances
When it may not be suitable
This HDMI v2.0 AOC delivers up to 18 Gbit/s bandwidth and supports 4K@60Hz, HDR and common audio formats, but it does not provide the higher bandwidth required for HDMI 2.1 features such as 4K at higher refresh rates, 8K resolutions, or uncompressed higher-bit-rate formats. For short, simple connections where a passive copper HDMI cable is sufficient, an active optical cable may be unnecessary.
Key specifications
Cable length: 25 m (available in lengths up to 100 m)
HDMI version: 2.0
Maximum data transfer rate: 18 Gbit/s
Supported resolution: up to 3840 x 2160 @ 60 Hz (4K@60Hz 4:4:4)
Audio: multi-channel audio, Dolby TrueHD, DTS-HD Master Audio, Audio Return Channel (ARC)
Shielding: aluminium foil shielding and copper-encased chipset; fully shielded design
Inner construction: copper and fiber with Kevlar protection
Cable jacket: Low Smoke Zero Halogen (LSZH)
Connector type: HDMI Type A (Standard) male to HDMI Type A (Standard) male
Colour: Black
How to use
Connect the HDMI Type A male connector labelled for the source to your source device (player, PC, set-top box) and the other labelled connector to the display or receiver. The cable is active and does not require external power. Ensure connectors are correctly oriented and seated fully to maintain shielding and signal integrity. For long runs, route the cable to avoid sharp bends and mechanical strain on the connectors and Kevlar core.
What to consider before purchase
Confirm you need HDMI 2.0 bandwidth (18 Gbit/s) and 4K@60Hz support rather than HDMI 2.1 features
Verify the required cable length; this item is 25 m but AOC technology is available up to 100 m
Check that LSZH jacket and full shielding are suitable or required for your installation environment
Ensure both devices use HDMI Type A connectors and support the audio/video features you need (HDR, ARC, HDCP 2.2)
Usage recommendations
For reliable 4K@60Hz delivery over long distances, use the marked source and display ends, avoid tight bends, and secure the cable to prevent strain. The LSZH jacket and full shielding make this cable appropriate for installations where fire-safety and low electromagnetic interference are priorities.
