What is an optical audio cable, and how does it work?
An optical audio cable, also known as a TOSLINK cable, is a type of digital audio cable that uses light to transmit audio signals. It works by converting the digital audio signal into a light signal, which is then transmitted through the cable to a receiver, such as a soundbar or home theater system. The receiver then converts the light signal back into a digital audio signal, which is played through the speakers.
The optical audio cable uses a technology called fiber optic transmission, which allows for high-quality digital audio transmission over long distances without degradation. This makes it an ideal solution for connecting devices such as PCs, gaming consoles, and Blu-ray players to home theater systems or soundbars.
