A very large volume neutrino telescope is being constructed in the Mediterranean Sea by the KM3NeT collaboration. Thousands of glass spheres holding a set of 31 small-area photomultipliers will be deployed at high depth forming a three-dimensional matrix. The glass spheres are the basic elements that will detect the Cherenkov light induced by charged particles produced in neutrino interactions with the surrounding matter. Time synchronization between photomultipliers is required to achieve optimal performance. Due to the high volume to be covered by KM3NeT, a cost reduction of the different systems is a priority. To this end a very low price calibration device, the so called Nanobeacon, has been designed and developed. In this article the main characteristics of the device are described.
