How optical jack works?

An optical jack, often referred to as a TOSLINK or optical audio connector, transmits digital audio signals using light. It employs a fiber optic cable to convert electrical audio signals into light pulses, which then travel through the fiber. At the receiving end, a photodetector converts the light back into electrical signals, ensuring high-quality audio transmission with minimal interference. This method allows for high-fidelity sound over longer distances without degradation.
