摘要:
PURPOSE: A noise eliminating apparatus in a wavelength division multiplexed-passive optical network (WDM-PON) system is provided to add a high pass filter (PHF) and to remove a noise. CONSTITUTION: An optical detecting unit (131) receives an optical signal received from an optical network unit (ONU). The optical detecting unit converts the received optical signal into an electric signal. A PHF removes a noise by back reflection in the electric signal converted by the optical detecting unit. An arrayed waveguide grating (AWG) (200) performs the wavelength division distribution of the signal received through a first fiber. The AWG applies the distributed signal to the optical detecting unit.
