what is an optical audio cable

An optical audio cable is a type of cable that transfers audio digital signals by light. Here is a detailed introduction:
Working principle: Inside the cable, light pulses are used to transmit audio information. At the sending end, the audio signal is converted into light pulses, which then travel through the optical fiber. At the receiving end, the light pulses are converted back into electrical pulses and then into analog signals that can be amplified and played through speakers.

Advantages:
High – quality audio transmission: It can provide high – fidelity audio, with low signal loss and minimal interference, ensuring stable and clear sound.
Strong anti – interference ability: Since it uses light to transmit signals instead of electrical signals, it is not affected by electromagnetic interference, which is common in metal cables.
Easy installation: It is suitable for most audio – visual equipment and is easy to connect.
Disadvantages:
Limited audio format support: It usually supports common audio formats such as 5.1 – channel Dolby Digital and DTS audio, but may not support some advanced audio formats.
Only for audio transmission: It can only transmit audio signals and cannot transmit video signals.
Application scenarios: It is commonly used to connect devices such as TVs, soundbars, home theater systems, and audio amplifiers. For example, when you want to connect a TV to an external sound system to enhance the audio effect, you can use an optical audio cable.
