Disclosed is a method for removing cross-talk in a wavelength division multiplexed passive optical network (WDM-PON). The WDM-PON and the method remove cross-talk between adjacent wavelength channels due to incomplete alignment of wavelength channels in a MUX/de-MUX between a central office and a remote node in the WDM-PON employing light-injected light sources. The WDM-PON includes at least two broadband light sources having different bands, which provide injection light to be injected to light-injected channels light sources, a transmitter receiving injection from the broadband light sources, injecting the injection light to odd channel light-injected light sources and even channel light-injected light sources, arraying odd and even channels in such a manner that the odd and even channels belong to different spectrum bands, multiplexing the signal according channels, and transmitting the multiplexed signal. The WDM-PON may also include a receiver for receiving the multiplexed signal transmitted from the transmitter and splitting the multiplexed signal according to the odd and even channels.
