wavelength-division multiple access passive optical network using the incoherent broadband light source

The present invention relates to a wavelength-division-multiplexed passive optical network using injected light. Wavelength-division-multiplexed passive optical network of the present invention consists of a central office, a remote node, the optical network. Central station, the country needs a terminating device (Optical line terminal) of a plurality of beams for a plurality of passive optical network. The present invention aims to configure the terminal equipment of a plurality of light for wavelength-division-multiplexed passive optical access network efficiently. Wavelength division multiplexing, a broadband light source, a passive optical network
