HDMI fibre optic cable SpeaKa Professional SP-12842664 20 m — single-link, black

SpeaKa Professional SP-12842664 is a 20 m single-link HDMI fibre optic cable in black designed for reliable long-distance transmission of digital video and audio. The cable uses an optical core instead of copper conductors to preserve signal quality over extended runs, reducing susceptibility to electromagnetic interference and attenuation. It supports standard HDMI connections for linking displays, projectors and AV equipment in environments where long cable runs are required.

Advantages

This HDMI fibre optic cable provides consistent high-bandwidth performance across a 20 m run while maintaining a compact, flexible form factor suitable for installation in conference rooms, home theatres and commercial AV setups. The use of optical transmission minimizes signal degradation and interference compared with long copper HDMI leads, enabling stable image and sound delivery. The single-link design simplifies compatibility with standard HDMI inputs and outputs and the black outer jacket offers discreet integration with most AV installations.

Suitable for

• Connecting a projector to a laptop or media player over long distances
• Linking wall-mounted or ceiling displays to AV receivers or sources
• Conference rooms and meeting spaces requiring tidy, reliable video links
• Home theatre installations with long cable routing needs
• Commercial AV setups where electromagnetic interference is a concern

Key specifications

• Cable length: 20 m
• Transmission medium: fibre optic core for signal carriage
• Link type: single-link HDMI
• Colour: black outer jacket
• Connectors: standard HDMI male to HDMI male form factor
• Designed use: digital video and audio transmission over extended distances

How to use

Route the cable between source and display, avoiding tight bends and sharp kinks that could stress the optical core. Connect the HDMI ends to the source device (such as a media player, laptop or AV receiver) and to the display device (projector, monitor or TV). Ensure both devices are powered and set to the correct input/output settings; most devices will detect the connection automatically. For clean installations, use cable clips or conduits to secure the cable along walls or ceilings while maintaining a minimum bend radius as recommended for optical cabling.

Usage recommendations

To preserve signal integrity, avoid repeated flexing near the connector ends and maintain gentle curves when routing. Keep the cable away from sources of mechanical stress and strong heat. For installations with long continuous runs, verify device HDMI settings and, if necessary, test the link at the required resolution and refresh rate before final installation.
