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

摘要

PURPOSE: An optical diplexer module using mixed signal multiplexing is provided to reduce the number of components and processes by implementing an optical diplexer module which enables a TPS(Triple-Play Service) and an MPS(Multiple-Play Service) through two optical wavelengths. CONSTITUTION: A multiplexing unit(210) outputs one multiplexing signal after multiplexing digital signals and at least one analog signal and a broadband digital signal of a baseband. A first up-mixer(211) converts the analog signal into a predetermined high frequency band, and a second up-mixer(215) converts the digital signal into the high frequency band. A multiplexer(213) outputs a multiplexing signal after mixing the output signal of each mixer with a baseband signal, and an electronic to optical converter(220) converts the multiplexing signal to an optical signal.
