ABSTRACT:
Provided is a WDM-PON system based on a wavelength-tunable ECL. A method of controlling an upstream optical wavelength of an ONT in WDM-PON system, the method comprises: determining upstream optical wavelength information of the ONT corresponding to a downstream optical wavelength predetermined to the ONT newly installed by being connected to a network; in an OLT, loading the determined upstream optical wavelength information onto the downstream optical wavelength assigned to the ONT and transmitting the loaded upstream optical wavelength information to the ONT; in the ONT, generating an upstream optical wavelength based on the upstream optical wavelength information transmitted by being loaded on the downstream optical wavelength from the OLT; and in the ONT, loading upstream data onto the generated upstream optical wavelength and transmitting the loaded upstream data to the OLT.
