Zusammenfassung:Provided is an Optical Line Terminal (OLT). The OLT may include a first Wavelength division multiplexer/demultiplexer (WDM MUX/DeMUX) to perform a wavelength demultiplexing on seed light received from a seed light source, and a second Wavelength division demultiplexer (WDM DeMUX) to receive, from at least one ONU/ONT, an upstream optical signal generated using the seed light having the wavelength demultiplexing performed, and to perform a wavelength multiplexing on the received upstream optical signal.
