Optical Audio Cable

Optical audio cables, also called TOSLINK cables (from Toshiba Link, the very first developer), transfer digital audio signals as light pulses through a thin optical fibre cable. This method offers several benefits compared to conventional electrical audio cables. They ensure a reliable and high-quality digital audio signal in various applications, especially in settings where possible electromagnetic interference can be a problem. They exhibit extreme immunity to noise and galvanic isolation, which makes them an excellent choice for myriad digital audio applications. 

Working Principle of Optical Audio Cable

Despite electrical signals, optical cables use light signals to transmit digital audio information. The core of the cable is a thin strand of either glass or plastic that transfers light through total internal reflection. At one side of the cable, an LED or laser diode transforms the electrical audio signal into light pulses. At the second end, a photodetector converts the light pulses back to an electrical signal that is understandable by the audio device.   

Standout Features and Benefits of Using Our Top-notch Optical Audio Cable

• Optical cables resist electromagnetic interference EMI, which can produce unwanted noise and distortion in electrical cables. 
• Provide galvanic isolation, meaning there is no electrical connection between the source and the destination. 
• Prevent ground loops and other electrical issues.   
• Supports high-resolution audio formats and multi-channel surround sound.   

Where Can I Use Optical Audio Cable?

• Connecting Audio Equipment: Connecting CD/DVD/Blu-ray players, gaming consoles, and computers to AV receivers, soundbars, and additional audio devices.   
• Home Theatres: Transferring digital audio signals among different components in a home theatre setup. 
• Professional Audio Equipment: Applied in recording studios and other professional-grade audio applications.
