Optický HDMI kábel Unitek C11092ASL01-40M — 40 m, podporuje 4K 60 Hz

The Unitek HDMI optical cable C11092ASL01-40M is a 40 m single-cable solution for long-distance HDMI connections. Designed to transmit 4K video at 60 Hz using optical signal transport, this cable maintains image fidelity and reduces signal loss that typically affects long copper HDMI runs. The cable is intended for installations where extended length and stable high-resolution AV transmission are required, such as home theatre setups, conference rooms, digital signage and projector links.

Advantages

Optical signal transport eliminates many attenuation and interference issues common with long copper HDMI cables, providing consistent 4K@60Hz delivery over 40 meters. The cable supports high-bandwidth video and preserves colour accuracy and detail across long distances. Its single, all-in-one design simplifies routing and installation compared with multi-cable extenders or active repeater systems.

Suitable for

• Connecting 4K TVs to remote source devices across rooms or floors
• Linking projectors in lecture halls, auditoriums and conference centres
• Digital signage installations requiring long cable runs with minimal signal loss
• AV receiver or media player setups where copper HDMI cannot reach reliably

Key specifications

• Cable length: 40 m
• Supported resolution and refresh rate: 4K (3840×2160) at 60 Hz
• Signal type: optical HDMI transport
• Connector type: standard HDMI male connectors (both ends)
• Compatibility: standard HDMI sources and displays supporting 4K@60Hz

How to use

Connect one HDMI end to the source device (such as a Blu-ray player, media streamer or AV receiver) and the other end to the display device (TV, projector or monitor). Ensure both connected devices are powered on and set to the correct HDMI input. When used with 4K@60Hz content, confirm that source and display devices support the target resolution and refresh rate. Avoid sharp bends and tight kinks along the cable path to preserve the optical fibre integrity.

Recommendations

For optimal performance, route the cable away from strong electromagnetic sources and provide gentle bend radii consistent with optical cable handling. Verify HDMI handshakes and display settings after installation; if the image does not appear, power-cycle the source and display, and re-seat connections. Use quality HDMI-compliant devices to ensure full 4K@60Hz compatibility.
