ABSTRACT:
A bidirectional optical communication system which includes a transmission ine which directs radiation onto a reflective surface through which a smaller-diameter fiber is inserted. The smaller-diameter fiber directs radiation into the larger-diameter fiber for transmission away from the reflective surface simultaneous with radiation transmitted through the larger-diameter fiber toward the reflective surface. A reflective surface and small fiber may be at each end of the larger-diameter fiber for bidirectional operation.
