Abstract : A bidirectional converter/interface for connecting several two-way broadband RF cables to a single pair of optical fibers is provided. In the reception mode, a broadband RF carrier of an optical conductor signal is directed to a plurality of bandpass filter/block converter combinations. These filter/converter combinations segment the broadband RF carrier into predetermined RF bands carrying the information. Each segmented band is then shifted (either up or down) to the receiving band frequency utilized by each of the RF systems. In the transmission mode, each transmitted signal from one of the RF systems is passed to a return path block converter/bandpass filter combination that shifts the entire transmitted band to a predetermined band. The predetermined bands are chosen such that each is a unique, non-overlapping band associated with a particular one of the RF systems. These unique bands are then combined into a single RF broadband signal that is converted to an optical signal and carried by a second optical conductor.
