摘要： PURPOSE: A noise suppressing apparatus and a wavelength division multiplexed-passive optical network (WDM-PON) system including the same are provided to amplify the high frequency band of a light source and to prevent the noise of a seed light generated from the light source. CONSTITUTION: An inverter unit (15) reverses the phase of an electric signal transformed from a transforming unit. A bandwidth compensating unit (17) amplifies a high frequency band of an electric signal generating a driving current which drives a light source. A light source driving unit (18) receives the electric signal of which the phase is reversed from the inverter unit. The light source driving unit generates a driving current which a light source drives through a signal of which a high frequency band is amplified by the bandwidth compensating unit. The light source driving unit supplies the generated driving current to the light source.

摘要： PURPOSE: A noise control device and a WDM-PON(Wavelength Division Multiplexed Passive Optical Network) system are provided to control noise generated from an optical source by using a feed forward method. CONSTITUTION: An optical coupler(11) divides received light. A converter(14) converts an optical signal received from the optical coupler into an electric signal. An inverter(15) changes a phase of the electric signal which is converted by the converter. An optical source driving unit(17) receives the phase of the electric signal which is reversed by the inverter. The optical driving unit provides a driving current which drives the optical source.
