Abstract: PURPOSE: A seed light module for wavelength division multiplexing-based passive optical networks and a method for the same are provided to increase the optical bandwidth of seed light by controlling the polarization of the seed light. CONSTITUTION: A reflector(250) reflects seed light from a light source generating part. A light attenuator(240) attenuates the intensity of the reflected seed light and outputs the attenuated seed light to the light source generating part. The light attenuator attenuates the intensity of seed light input from the light generating part and outputs the attenuated seed light to the reflector. A polarization controlling part(220) controls the polarized direction of the seed light generated from the light source generating part and outputs the controlled seed light to the reflector.
