TOSLINK is a standardized optical fiber connection system. Its most common use is in consumer audio equipment (via a "digital optical" socket), where it carries a digital audio stream between components. TOSLINK may use inexpensive 1 mm plastic optical fiber or it can use higher quality multi-strand plastic optical fibers. Many motherboards have a TOSLINK output that can be hooked up to an amplifier for high quality audio output.
