The United Nations “International year of light 2015” strives to highlight the importance of optical technologies in our everyday lives. Fibre optic communication is one such technology: the growth of internet and its associated services are enabled by the vast transmission bandwidth provided by optical networks. However, the general public is not well aware of the optical and electronic fundamentals of the underlying transmission systems. Here we present the development of a bachelor thesis in Telecommunication Engineering in which a small-scale fibre-optic link is built and the electronics required to transmit music over this link are implemented. The resulting system demonstrates, in a very intuitive way, how information is transmitted over an optical fibre.
