Toslink fibre optic audio cable 2m black PMMA 1mm core digital audio cable for audio and video equipment with 4mm square mouth connectors on opposite sides
2-Metre Toslink Digital Audio Cable with 1mm PMMA Core for Audio/Video Equipment

This black Toslink fibre optic audio cable provides a dedicated digital audio connection between compatible entertainment components. Measuring 2 metres in length, it offers practical reach for typical home theatre setups while maintaining signal integrity through its fibre optic construction. The cable uses standard 4mm square mouth connectors positioned on opposite ends, making it compatible with most audio receivers, soundbars, televisions, and other devices featuring Toslink digital audio ports.
Features and Construction

This cable is designed specifically for digital audio transmission using the Toslink optical standard. Its construction focuses on reliable signal transfer between audio and video equipment without the electrical interference that can affect traditional copper cables.
Material and Build
The cable utilises a 1mm core made from PMMA (polymethyl methacrylate), a type of plastic optical fibre that transmits digital audio signals as pulses of light. This fibre optic approach eliminates ground loops and electrical interference that can degrade audio quality in analogue or electrical digital connections. The exterior sheathing is black, providing both protection for the internal fibre and discreet appearance that blends with most entertainment equipment.
Size and Practical Fit
With a total length of 2 metres, this cable provides sufficient reach for typical component placement in home entertainment setups. This allows flexible positioning of audio and video equipment without requiring devices to be placed immediately adjacent to each other. The 4mm square mouth connectors are standard for Toslink applications, ensuring compatibility with the majority of devices featuring optical audio ports.
Uses and Placement

This cable serves as a dedicated digital audio link between components in various entertainment configurations. Its fibre optic nature makes it particularly suitable for setups where electrical isolation between devices is beneficial for audio quality.
Event or Professional Use
In professional audio environments or event setups, this cable can connect digital audio sources to processing equipment or amplifiers. The fibre optic transmission prevents ground hum and electrical noise that can be problematic in complex installations with multiple power sources. The 2-metre length provides practical routing options between rack-mounted equipment or temporary setups.
Everyday Home Use
For home entertainment systems, this cable connects devices like Blu-ray players, games consoles, set-top boxes, or media streamers to audio receivers or soundbars. It transmits multi-channel surround sound formats like Dolby Digital and DTS without quality loss that can occur with electrical connections. The black colour helps it blend discreetly behind entertainment centres and television stands.
Benefits and Buying Value

This cable offers specific advantages for digital audio transmission compared to alternative connection methods. Its design addresses practical considerations for both signal quality and physical installation.
Reuse and Low Maintenance
The durable construction allows for repeated connection and disconnection as equipment configurations change. Fibre optic cables require minimal maintenance beyond keeping connectors clean and free from dust. Unlike electrical cables that can degrade with bending, the optical fibre maintains signal integrity provided it isn't sharply kinked or subjected to excessive tension.
Why Choose This Product
This cable provides a dedicated Toslink solution with specifications matched to common audio/video setup requirements. The 2-metre length accommodates typical component spacing while avoiding excess cable that requires management. The opposite-side connector configuration ensures straightforward installation without needing to consider orientation beyond connecting the correct ends to source and receiver devices.
