## Long description

The HDMI active optical cable WENTRONIC 76278 supports up to 8K resolution and uses optical signal transmission to preserve picture and sound quality over long distances. Designed for connecting HDMI-enabled devices such as TVs, monitors, projectors and AV receivers, this cable reduces signal loss and is less susceptible to electromagnetic interference than traditional copper cables. It is intended for installations where reliable high-resolution video and audio delivery is required across extended runs.
Advantages
The active optical design enables long-range transmission without the weight and bulk of very thick copper cables while maintaining bandwidth required for high-resolution video formats. Support for 8K resolution ensures compatibility with modern displays and content sources. Optical transmission minimizes electromagnetic interference and crosstalk, making the cable suitable for environments with many electronic devices. The cable also supports standard HDMI signal features, allowing both video and multichannel audio to be carried over a single connection.
Suitable for
 Home theater systems with high-resolution TVs and AV receivers
 Conference rooms and meeting spaces with long cable runs to projectors or displays
 Digital signage and professional installations requiring consistent image quality over distance
 Workstations and multi-monitor setups where distance between devices exceeds typical copper HDMI limits
Key specifications
 Signal type: active optical HDMI transmission
 Maximum supported resolution: up to 8K
 Transmission advantage: reduced signal loss and low susceptibility to electromagnetic interference
 Compatibility: standard HDMI-enabled displays, projectors and AV receivers
 Cable use case: long-range video and audio transmission
How to use
Connect one HDMI connector to the source device (for example a Blu-ray player, streaming box, PC or AV receiver) and the other HDMI connector to the display device (TV, monitor or projector). Ensure both connected devices are powered on and set to the correct HDMI input. The cable handles both video and audio signals; any device-side settings for resolution or audio format should be configured on the source or display as needed. When routing the cable, avoid sharp bends and excessive tension to maintain optical integrity.
Usage recommendations
For best performance, use this active optical HDMI cable for runs that exceed standard copper HDMI length limitations. Verify that connected equipment supports the desired 8K resolution and associated refresh rates. Avoid tightly coiling the cable and keep it away from sources of extreme heat; check device HDMI settings after installation to confirm signal negotiation and desired audio/video formats.
