An optical in connection, also known as TOSLINK or SPDIF, is used to input an optical digital audio signal into a device, such as a soundbar or receiver. This allows the device to receive and process the audio signal from an external source, such as a Blu-ray player or gaming console. On the other hand, an optical out connection is used to output an optical digital audio signal from a device to another external device, such as a soundbar or amplifier. This allows the device to send the audio signal to another device for playback or further processing. In summary, an optical in connection receives an audio signal, while an optical out connection sends an audio signal. **
