ABSTRACT:
The present invention pertains to an asymmetrical bidirectional optical communication system of the type comprising a central station, a plurality of user stations, and a plurality of bidirectional optical transmission paths, one of which connects the central station and one of the user stations. The central station is provided with a laser for initiating in the optical transmission path the propagation at a wavelength in the 1100-1700 nm window of a single-mode signal. Each user station is provided with a light source which initiates in the optical transmission path the propagation at a wavelength in the 700-950 nm window of a few-mode signal. Each optical transmission path comprises an optical fiber having transmission characteristics such that the single-mode signal propagates with a total dispersion less than 5 ps/km-nm and the few mode signal propagates with a bandwidth greater than 1 GHz-km.
