OD2.2 Digital Audio Optical Fibre Cable for Clear Signal Transmission in 1.5M to 30M Lengths

This OD2.2 specification digital audio optical cable is designed for transmitting a pure, digital audio signal between compatible components. Using a light-based signal via its imported fibre core, it carries audio data without the electromagnetic interference or signal degradation that can affect traditional copper connections. The robust PVC jacket provides essential physical protection for the delicate internal fibre, making it suitable for permanent installations or regular use in home theatre setups, gaming consoles, and audio streaming devices. With a comprehensive range of lengths available, you can select the precise cable needed for your specific equipment layout, from a short 1.5-metre run to a long 30-metre connection.

Features and Construction

This cable's performance and durability stem from its specific construction and material choices, all centred on reliable digital audio transmission.

Material and Build

The core of this cable is a single strand of imported optical fibre, which is the medium for transmitting the digital audio signal as pulses of light. This method ensures the signal integrity is maintained from source to receiver. The fibre is encased within a PVC (Polyvinyl Chloride) jacket. This sheath, with a specified thickness of 2.2mm, serves as the primary physical barrier. It protects the fragile glass or plastic fibre inside from being crushed, abraded, or exposed to dust and minor environmental factors that could compromise the light path and signal clarity.

Size and Practical Fit

The cable has a slim profile with a maximum outer diameter of 2.2mm, allowing it to be routed discreetly behind media units or through cable management channels. Its flexibility facilitates installation even in tight spaces. The key practical advantage is the extensive choice of lengths. Whether you need a short 1-metre cable for devices stacked closely together, a standard 3 or 5-metre length for a typical TV-to-soundbar setup, or a long 20 to 30-metre run for a custom home cinema installation, this range covers the requirement. Available sizes include 1M, 1.5M, 1.8M, 2M, 3M, 5M, 8M, 10M, 12M, 15M, 20M, 25M, and 30M.

Uses and Placement

This optical cable is intended for specific digital audio connections in various domestic and semi-professional environments.

Event or Professional Use

In settings where clean, uncompressed digital audio needs to be sent over a distance without quality loss, such as between a mixing desk and a recording interface in a simple studio setup, or from a media player to a PA system at a small event, the longer length options (10M to 30M) are applicable. The light-based transmission is inherently resistant to the electrical noise often found in such environments, providing a reliable connection.

Everyday Home Use

This is the most common application. The cable connects the optical digital audio output on modern televisions, Blu-ray players, games consoles (like PlayStation and Xbox), and streaming boxes to the corresponding optical input on soundbars, AV receivers, or DACs (Digital-to-Analogue Converters). It enables high-quality surround sound formats like Dolby Digital and DTS to be passed from the source to your audio system, forming a critical link in a home theatre or high-fidelity audio setup.

Benefits and Buying Value

The value of this cable lies in its specific function, construction quality, and the practicality offered by its length options.

Reuse and Low Maintenance

As a purely digital and passive connection, the cable has no active components to fail. With careful handling—avoiding sharp bends or heavy crushing—the internal fibre and PVC jacket provide a long service life. It can be unplugged and reused in different setups as your equipment changes. No electrical power, signal boosting, or periodic maintenance is required; it is a simple, plug-and-play component.

Why Choose This Product

You would select this specific OD2.2 audio cable when you need a reliable digital optical connection and the exact length matters for a neat and functional installation. The clarity of its imported fibre core for signal transmission, combined with the protective PVC jacket, offers a balanced solution focused on the core task of moving digital audio data without alteration. The wide array of lengths means you are not forced to use a cable that is too short or excessively long and messy, allowing for a tailored and tidy AV setup.
