ABSTRACT:
An optical fibre communication network comprising one optical source (1) connected to one end of an optical fibre (3), and several optical receivers (9) for detecting light scattered to the side of the optical fibre (3), the network being characterized by the fact that each optical receiver (9) is sufficiently sensitive to require for reliable communication only light lost by the fundamental scattering of the fibre (3) during normal propagation of the light originating in said optical source (1) while travelling in the vicinity of the optical receiver (9).
