HDMI optical cable Unitek C11092ASL01-70M 4K 60Hz 70 m

Unitek C11092ASL01-70M is a 70-meter HDMI optical cable engineered for long-distance digital video and audio transmission. The cable supports up to 4K resolution at 60 Hz and uses optical fiber to preserve signal integrity across extended runs, reducing electromagnetic interference and signal attenuation typical of long copper HDMI cables. It is intended for fixed AV installations where dependable high-bandwidth delivery is required over tens of meters.

Advantages

The optical construction provides stable 4K/60Hz performance over 70 m with minimal loss and no need for external repeaters. Its immunity to electromagnetic interference makes it suitable for installation alongside power lines and in complex cabling environments. The cable delivers uncompressed HDMI signals including high-resolution video and multichannel audio, enabling consistent playback and display quality in professional AV setups.

Suitable for

• Conference rooms and boardrooms requiring long HDMI runs
• Lecture halls, classrooms, and auditoriums with wall-mounted displays or projectors
• Digital signage installations in retail, hospitality, and public spaces
• AV integration projects where EMI resistance and signal integrity are critical

Key specifications

• Cable type: HDMI over optical fiber
• Length: 70 meters
• Maximum supported resolution: 4K (3840 × 2160) at 60 Hz
• Signal: Uncompressed digital video and multichannel audio transmission
• EMI immunity: Optical fiber core provides resistance to electromagnetic interference
• Typical use: Fixed installations for long-distance HDMI connectivity

How to use

Connect one HDMI end to the source device and the other end to the display or receiver, ensuring connectors are fully seated. Route the cable through conduits, cable trays, or along walls as necessary; avoid sharp bends that exceed the cable’s minimum bend radius. The cable transmits the HDMI signal directly over optical fiber, so no inline amplifiers or repeaters are required for the rated 70 m length. Verify that source and display support 4K/60Hz and configure video output settings on the source device as needed.

Recommendations

For reliable operation, protect termination points from moisture and mechanical stress, secure the cable along its route to prevent strain on connectors, and avoid tight looping or kinking. Test the full signal chain after installation to confirm 4K/60Hz modes and audio passthrough. If adapters or extenders are used, verify they are compatible with HDMI 2.0-level bandwidth to maintain 4K/60Hz performance.
