Abstract
The present invention is an optical telecommunications system capable of setting up connections between particular pairs of subscriber stations. Illustratively, the Fourier components of radiation pulses produced in a first specific subscriber station are independently phase modulated in accordance with a predetermined code chosen so that the radiation pulse can be detected only in a second specific subscriber station.
