NOISE CONTROL DEVICE AND A WAVELENGTH DIVISION MULTIPLEXED PASSIVE OPTICAL NETWORK SYSTEM INCLUDING THE SAME, CAPABLE OF IMPROVING THE TRANSMISSION SPEED AND QUALITY OF AN OPTICAL COMMUNICATION NETWORK
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.;COPYRIGHT KIPO 2013;[Reference numerals] (11) Optical coupler; (12) Optical delaying unit; (13) Optical source; (14) Converter; (15) Inverter; (16) Amplifying unit; (17) Optical source driving unit; (2) Optical source for injection
