Some basic methods of bidirectional communication in a single fiber in practice are introduced in this paper. The way of wavelength division multiplexing bidirectional communication is analyzed and the performances desired are given. The technology of sub carrier bidirectional communication. in a single fiber is discussed on emphasis. The problem of self transmitting and self receiving is resolved by frequency division technology in electrical field. On this basis, the performance of directional filter is determined. At last, the performances of a realized system with sub carrier bidirectional communication. technology in a single fiber are given.
