Cavo prolunga HDMI Kindermann Konnect Design 25 m – cavo ottico attivo 4K 60 Hz

The Kindermann Konnect design HDMI extension cable, 25 m, is an active optical cable engineered to carry HDMI signals over long distances while maintaining 4K resolution at 60 Hz. The cable uses optical transmission for the video and high-speed data channels to reduce signal attenuation and ensure stable image and audio delivery between source devices and displays. Its 25-metre length is suitable for installations where a passive copper cable would fail to preserve full bandwidth and resolution.

Advantages

The active optical design minimises signal loss and prevents degradation typical of long copper HDMI runs, preserving 4K@60Hz video quality and HDR metadata where supported. The cable is thin and flexible compared with bulky copper alternatives, simplifying routing through walls, ceilings, and conduits. It supports standard HDMI features such as audio return and high-bandwidth digital audio formats, delivering a reliable connection for AV systems in professional and residential environments.

Key specifications

How to use

Connect the cable’s HDMI connectors to the HDMI output of the source device and the HDMI input of the display. Ensure both devices are powered on and set to the correct HDMI input. The cable is bidirectional for the HDMI signal path and requires no external power in typical installations; if a device requires specific HDMI settings (resolution, refresh rate or HDR mode), adjust those in the source device’s display settings to match the display capabilities. Route the cable avoiding tight bends and sharp edges to maintain the fibre integrity.

Recommendations

For best results, verify that connected devices support 4K@60Hz and compatible HDMI features. Avoid excessive bending radii and secure the cable with gentle straps or clips; do not crush or staple the cable. If using in-wall or concealed installations, check local regulations and use appropriate conduit or fire-rated materials as required.
