OPTICAL DIPLEXER MODULE USING MIXED-SIGNAL MULTIPLEXER AND METHOD USING THE SAME

摘要

An optical diplexer module using a mixed-signal multiplexer and a method using the same are provided to realize an optical diplexer module which enables an MPS(Multiple-Play Service) and a TPS(Triple-play service) by using only two optical wavelength for an uplink and downlink signals. A multiplexing unit(210) multiplexes a wideband digital signal and an analog signal, and then outputs those signals in one multiplexing signal. A multiplexer(213) mixes an output signal of each mixer with a baseband signal and outputs the mixed signal as a multiplexing signal. An optical converter outputs converts the multiplexing signal into an optical signal and outputs the optical signal. A photoelectric converter(240) converts the optical signal received from the outside into an electric signal. An amplifier(250) performs an amplification function that amplifies the output signal of the photoelectric converter.
