Digital coaxial audio cables are a specific type of coaxial cable used for transmitting digital audio signals between audio devices. Unlike analog coaxial cables that carry varying voltage levels representing analog audio signals, digital coaxial audio cables transmit audio data in a digital format, preserving the integrity of the signal and minimising interference.

Here are key features and uses of digital coaxial audio cables:

1. Digital Transmission: Digital coaxial audio cables are designed to carry digital audio signals, typically in formats like PCM (Pulse Code Modulation) or Dolby Digital. The digital nature of the signal ensures a high level of audio fidelity and minimises the degradation that can occur in analog connections.

2. RCA Connectors: Similar to analog RCA cables, digital coaxial audio cables use RCA connectors, often colour-coded in orange. These connectors are used to ensure a secure connection and minimise signal loss.

3. Compatibility: Digital coaxial audio cables are commonly used to connect audio sources like DVD players, Blu-ray players, CD players, gaming consoles, and set-top boxes to audio receivers, soundbars, and home theatre systems. They provide a simple way to transmit high-quality audio between these devices.

4. SPDIF (Sony/Philips Digital Interface) Standard: Digital coaxial audio cables often follow the SPDIF standard, which specifies the format for transmitting digital audio between devices. SPDIF can support stereo or multi-channel audio, depending on the specific implementation.

5. Surround Sound: Digital coaxial audio cables can transmit multi-channel audio formats like Dolby Digital and DTS, making them suitable for home theatre setups that require immersive surround sound.

6. Signal Integrity: While digital coaxial audio cables are less susceptible to interference compared to analog cables, they can still experience signal degradation over longer cable runs. It's important to use high-quality cables and keep cable lengths reasonable to maintain signal integrity.

7. Use Cases: Digital coaxial audio cables are commonly used in setups where higher audio quality is desired, such as home theatre, gaming systems, and audio recording setups.

8. Audio Return Channel (ARC): Some digital coaxial audio cables can also be used to carry audio signals back from a TV to an audio receiver using the Audio Return Channel (ARC) feature. This simplifies the connection in home theater setups by allowing audio to be sent back to the receiver through the same cable that's used for video.

It's important to note that digital coaxial audio cables are different from regular coaxial cables used for purposes like video transmission or networking. When using digital coaxial audio cables, make sure the devices on both ends support the same digital audio format and that you're using the correct connectors for a proper connection.
