Abstract
A system for multiplexed transmission of different wavelengths of light comprises an array of at least two light sources whose images are formed on the end of an optical fibre. The images have displaced spectra so that a different part of the spectrum of each light source is imaged on to the end of the optical fibre and each part is transmitted by the optical fibre. The images themselves may be displaced by displacing the light sources. A number of such arrays having light sources with emission spectra centered on different wavelengths may be used to increase the number of multiplexed transmission channels.
