Abstract
A spectrum-sliced seed light module for a wavelength division multiplexing passive optical network (WDM PON) is provided. The seed light module includes an optical amplifier to amplify seed light, an optical wavelength filter to transmit broadband light, which is output in opposite direction to an output direction of the seed light, at periodic frequency intervals, and a reflective mirror to reflect light which is spectrum-sliced through the optical wavelength filter to the optical wavelength filter.
