Optical Audio Cable AB-COM 1.5 m — Toslink digital audio cable

The AB-COM 1.5 m Optical Audio Cable (Toslink) is a fibre-optic digital audio cable designed to transmit stereo and multichannel audio signals between devices equipped with optical S/PDIF ports. With a 1.5-metre length, this Toslink cable connects TVs, soundbars, AV receivers, DACs and other audio sources to playback equipment while providing electrical isolation and reduced susceptibility to electromagnetic interference for consistent signal integrity.

Advantages

This optical audio cable delivers low-loss digital audio transmission over a plastic optical fibre, ensuring accurate reproduction of stereo and multichannel formats without ground-loop noise. The Toslink connector provides a secure, standardized fit for compatible optical ports, and the 1.5 m length offers flexibility for typical home theatre or hi‑fi layouts. Because it uses light rather than electrical conductors, the cable is immune to common electrical interference and avoids introducing hum from nearby equipment.

Suitable for

• Connecting a TV to a soundbar or home theatre system
• Linking an AV receiver to digital sources such as set-top boxes or media players
• Running an external DAC from an optical output for improved audio playback
• Use in hi‑fi setups where electrical isolation is desired

Key specifications

• Connector type: Toslink optical S/PDIF compatible
• Cable length: 1.5 metres
• Transmission medium: plastic optical fibre (POF)
• Supported signals: digital stereo and multichannel audio via optical S/PDIF
• Electrical isolation: inherent (optical transmission)

How to use

Ensure both source and destination devices have compatible optical S/PDIF (Toslink) ports. With power off or volume muted on connected equipment, align the Toslink connectors and insert them gently into the optical ports until they click or seat securely. Select the optical audio output on the source device and set the receiving device to the corresponding input. Verify audio formats supported by both devices and adjust digital audio settings if required to match stereo or multichannel playback.

Usage recommendations

Avoid sharp bends and heavy kinks in the optical cable to maintain signal quality. Keep the cable away from intense heat sources and secure connectors when routing behind furniture. If you experience loss of signal, check connector seating and inspect the protective caps for dust; clean connectors with a soft, dry cloth if necessary.
