OPTIC TRANSMITTER USING WAVELENGTH DIVISION MULTIPLEXING

摘要

PURPOSE: An optical transmission apparatus using a wavelength allocation multiplexing method is provided to monitor optical signals by using monitor light reception devices. CONSTITUTION: A multiple channels optical transmission module(120) emits light to one monitor light reception device through an optical splitter(125) and plural wavelength allocation multiple filters. The light transmission module emits light to an optical fiber through a collimator(127). An optical output control module(140) controls operation current inputted to plural laser diodes by receiving feedback from other multiple wavelength optical signals.
