Optical audio cable 20.0 m, Toslink compatible, No name

Optical audio cable 20.0 m, Toslink compatible, No name is a 20-metre fiber-optic lead designed for digital audio transmission between devices equipped with optical S/PDIF ports. The cable supports stereo and multichannel digital audio signals and transmits audio via optical fiber to avoid electrical interference and ground loop problems. Its length makes it suitable for installations where devices are placed at a distance, such as living rooms, home theater setups or professional AV racks.

Advantages

This Toslink-compatible optical cable provides galvanic isolation between connected devices, eliminating hum and radio-frequency interference that can affect analogue connections. The 20.0 m length allows flexible placement of components without signal degradation over typical home and small professional distances. The cable’s optical transmission ensures consistent audio quality for stereo and multichannel formats and is compatible with a wide range of consumer audio equipment that use S/PDIF optical ports.

Suitable for

• Connecting a TV to a soundbar or AV receiver where HDMI ARC is not used or unavailable
• Linking CD/DVD/Blu-ray players and digital audio players to receivers or amplifiers
• Extending optical connections in home theater layouts and conference rooms
• Audio routing between audio interfaces or processors in studio setups that accept Toslink S/PDIF

Key specifications

• Length: 20.0 metres
• Connector type: Toslink-compatible optical S/PDIF
• Signal type: Digital optical audio (stereo and multichannel)
• Transmission medium: Optical fiber for immunity to electrical interference
• Typical applications: Home theater, TV to soundbar/receiver connections, digital audio devices

How to use

Insert the Toslink-compatible connector into the optical output of the source device and the optical input of the destination device, taking care to align connectors without forcing them. Ensure both devices are powered on and set to the correct input/output mode for optical S/PDIF audio. Avoid sharp bends or kinks in the cable; maintain gentle curves to preserve the optical fiber. If signal is not detected, check device settings (audio output set to optical) and confirm connectors are fully seated.

Usage recommendations

For reliable long-term performance, route the cable away from heavy foot-traffic areas and mechanical pinch points, and avoid coiling tightly. If used in a permanent installation, secure the cable with clips or cable ties placed loosely around the jacket. When connecting equipment at significant distances, verify device compatibility with optical S/PDIF signal formats and select the appropriate audio output mode on source devices.
