FIBER OPTIC COMMUNICATIONS USING OPTICAL SINGLE SIDE BAND TRANSMISSION AND DIRECT DETECTION

摘要

A fiber optic communications system includes a single sideband transmitter coupled to a direct detection receiver via an optical fiber. The single sideband transmitter generates an optical data signal, which includes an optical carrier and a primary optical sideband containing information to be transmitted. The non-primary optical sideband is either attenuated or non-existent. The direct detection receiver recovers the information form the optical data signal.
