What is an optical cable, and how does it work?
An optical cable, also known as a Toslink cable, is a type of cable used to transmit digital audio signals between devices. It uses light to transmit the signal through a fiber optic cable, allowing for a high-quality, interference-free connection. Optical cables are commonly used to connect devices such as TVs, soundbars, and Blu-ray players.
In terms of how it works, an optical cable sends digital audio signals as light pulses through the fiber optic core of the cable. These light pulses are then received by the device on the other end, which converts them back into a digital audio signal. This allows the device to process and play back the audio signal without any degradation or interference.
