Optical audio cable LIBOX LB0028 Toslink 4.0 mm, length 1.5 m

LIBOX LB0028 Toslink optical audio cable with a 4.0 mm outer jacket and 1.5 m length is designed for digital audio transmission between devices equipped with Toslink ports. The cable carries S/PDIF-format stereo and multi-channel signals without converting to electrical form, providing a fiber-optic link that is inherently immune to electromagnetic interference. It is suitable for connecting TVs, soundbars, AV receivers, CD players and other audio/video equipment in home theater and hi‑fi setups.

Advantages

The optical construction eliminates ground loops and reduces susceptibility to radio-frequency and electromagnetic noise compared with copper interconnects. A 4.0 mm jacket gives the cable flexibility while protecting the optical fiber from bending and mechanical damage. With a 1.5 m length the cable balances reach and neat installation in typical living-room and entertainment-center configurations. The Toslink terminations are compatible with standard optical ports on consumer audio equipment.

Suitable for

• Connecting TV to soundbar or home theatre receiver
• Linking CD/DVD/Blu-ray players to AV receivers
• Routing digital audio in hi‑fi and multimedia systems
• Replacing damaged or worn optical audio cables

Key specifications

• Cable type: Toslink optical (fiber-optic)
• Outer jacket diameter: 4.0 mm
• Length: 1.5 m
• Signal format: S/PDIF stereo and multichannel digital audio
• Connector type: standard Toslink optical plugs
• Immunity: resistant to electromagnetic and radio-frequency interference

How to use

Ensure both source and target devices have compatible Toslink optical ports, then remove any dust caps from the cable ends. Align each Toslink plug with the optical port and insert gently until it seats; do not force or bend the cable sharply near the connector. Select the optical audio output on the source device and, if necessary, set the input mode on the receiving device to the corresponding optical input. Verify audio format compatibility (some devices may require setting output to PCM or a specific multi-channel mode).

Usage recommendations

Route the cable avoiding tight bends and sharp edges; maintain a gentle radius to protect the fiber. Keep optical ports covered when not in use to prevent dust accumulation. For best results in longer or professional installations consider checking device manuals for supported audio formats and, if needed, using dedicated optical extenders or higher-specification fiber solutions.
