Optical audio cable ShiverPeaks 69012-1.0 Toslink (square) to 3.5 mm, 1.0 m, 2.2 mm ferrule

The Optical audio cable ShiverPeaks 69012-1.0 Toslink (square) to 3.5 mm, 1.0 m, 2.2 mm ferrule is a one-metre digital optical lead designed to connect devices with a square Toslink output to equipment that accepts a 3.5 mm optical input. The cable uses a 2.2 mm ferrule to ensure secure transmission of optical (light-based) audio signals and is intended for PCM and multichannel audio formats where Toslink-style terminations are used. Its compact length and connectors make it suitable for short, direct connections between TVs, soundbars, DACs and portable audio players without introducing electrical interference.

Advantages

This optical cable transmits digital audio via light, eliminating the risk of electromagnetic interference and ground loop noise that can affect electrical connections. The 2.2 mm ferrule provides a snug fit in compatible 3.5 mm optical jacks while the square Toslink connector ensures compatibility with common optical outputs on consumer electronics. At 1.0 m length the cable reduces excess slack and signal loss over short distances and is easy to route in home entertainment setups.

Suitable for

• Connecting a TV to a soundbar or home theatre system with a 3.5 mm optical input
• Linking portable audio players or DACs with Toslink outputs to devices that accept 3.5 mm optical plugs
• Short-distance digital audio connections in living rooms, bedrooms, or AV cabinets
• Applications where immunity to electrical interference is required

Key specifications

• Cable type: optical (Toslink to 3.5 mm optical)
• Connector A: square Toslink optical plug
• Connector B: 3.5 mm optical plug with 2.2 mm ferrule
• Length: 1.0 metre
• Signal supported: digital optical audio (PCM and multichannel formats)
• Signal transmission: light-based, immune to electromagnetic interference

How to use

Insert the square Toslink plug into the optical output of the source device until it seats gently; the connector is keyed to prevent incorrect insertion. Insert the 3.5 mm optical plug with the 2.2 mm ferrule into the optical input of the target device. Ensure both devices are powered off when making the connection, then power them on and select the appropriate digital audio input or output setting. Verify audio format compatibility (PCM or multichannel) in the source device settings if you do not hear sound.

Recommendations

Route the cable without sharp bends and avoid compressing it under heavy objects; maintain gentle curves to preserve the optical fibre. For stable performance, keep cable length appropriate to the distance between devices and avoid using adapters or extensions that are not specified for optical signal transmission.
