This picture demonstrates a TOSLINK optical fibre conducting light though multiple loops.  An ordinary laser pointer is aimed at the one end of the fibre (at the bottom right hand corner of the picture).  The light emerges at the other end (top left).

Here are the two TOSLINK connectors.  The matchstick between them provides a sense of scale.  The fibre has a diameter of about 1mm.
