Kind Code:
A1
Abstract:
A method of communication includes receiving, by an optical line terminal (OLT), a registration request from an optical network unit (ONU) through a specific upstream wavelength, assigning, by the OLT, out of a plurality of normal service upstream wavelengths and a plurality of normal service downstream wavelengths in a wavelength resource pool, a normal service upstream wavelength and a normal service downstream wavelength to the ONU for a normal service between the ONU and the OLT, and informing, through a specific downstream wavelength, the ONU of information regarding the normal service upstream wavelength and the normal service downstream wavelength. The specific downstream and upstream wavelengths are reserved for a registration process that includes receiving, through the specific upstream wavelength, the registration request and sending, through the specific downstream wavelength, the information regarding the normal service upstream wavelength and the normal service downstream wavelength.
